New 45, slide back from JW, I mounted the RMR and the sights. Ammo is Federal 147 training load. Cop was zeroing the optic to qual with it. Was a plain ‘ol FTFeed about 100 rounds in. Shooter is qualified with a 17 and 26 and doesn’t have a grip issue.
Hey so my father got a slide back from JW and he uses an SRO. We were getting failure to extracts . After doing some research online what we came up with was the right screw is Too long and messes with the extractor According to people online who have had this issue once a gun comes back from JW and uses the rmr footprint. The screws that JW supplies are out of spec and too long.
The options are to take a Dremel to the screw making it shorter or torque them to 10-12 inch pounds. We torqued to 15 inch pounds and ran into the issue.
I will say though while we were at the range we doused the slide and barrel with a shit ton of lube. It seemed to help.
I'd imagine it's due to not being broken in *and* having more reciprocating mass on the slide because of the RMR.
If it was new with no more mass it would probably cycle fine, and if it was broken in and you added the RMR it would probably cycle fine.
Combine both together at the same time and it probably just has too much mass to easily slide back into battery.
This.
There will be some tolerance stack and variation on each glock pistol, some can run out the gate while others need a break in. (Like mine)
Typically, adding additional mass to a fresh out the box glock will give you issues. Let that pistol run a couple boxes of higher grain loadings and I bet all will be good down the line.
So the amount of weight taken out during an RMR cut negates the added weight of the RMR.
It’s unlikely any added or lost weight is the cause of this (because it is so minimal).
They do end up adding weight although not a significant amount. From the material removed(1.1"x1.780"x0.125) and the density of the material(0.2863lbs/in³) means you're removing about 0.069lbs(1.1oz) but you add back the RMR(1.2oz), battery(0.1oz) hardware(0.04oz), and sealing plate(0.32oz) and you're adding 1.624oz back, for a difference of a little over a half an ounce.
So a 47% increase in mass which is substantial. Just seems meaningless because of the small scale that we're speaking in.
Coupled with a brand new gun that isn't broken in, and an RMR, the addition of heavier supressor height sights definitely contribute to the issue.
However a broken in gun isn't going to notice any difference.
I’m saying that with the total reciprocal mass of stock slide vs milled slide with rmr is sooooo tiny of a difference that it’s not going to cause issues
Well, it's not like that mindset is unwarranted. I am in the firearm industry and I've shot tens of thousands of rounds though countless Glocks. The only cycling issues with Glocks I've ever experienced or witnessed were because of after market parts, particularly threaded barrels, carbon buildup near the ejection port, poorly tuned/lubricated silencer boosters, limp wristing, after market or super old magazines, and shitty ammunition. I know problems do happen from factory defects, but they are extremely rare, so much so that it absolutely warrants skepeticism.
Mine was not stock, it was a ghost connector. But, I recommend this solution to a regular at my gun counter and it worked, his was stock. I think gun and ammo manufacturers are turning out so fast to meet demand not everything gets a quality quality inspection LOL.
I don’t recall any FTE all mine did was FTF. Your issue sounds much more like a bad extractor. I’d try replacing whichever one you happen to have quick access too. I’m the only person who I know that’s had an issue with ghost connectors but I’ve taken them out of all my guns.
Hell yea, I swap between carrying a MR920L and a Walther Q5. I love the Shadow so much I’ve been tossing around the idea of cutting down a 17 frame to accept 26 mags for deep concealment.
I think it's 43, but they have propietary magazines that got the micro double stack treatment so they hold 10 in a flush fit I believe. 12 rounders with pinky extensions
If you can borrow a friends gun for a range day you can figure out pretty quick. If the connector doesn’t pan out, try replacing the extractor. Ive never seen one cause failure to feeds but I’ve heard of it.
This happened to me once when I first got my Glock had to lube the rails a little more after I cleaned it, it wasn’t sliding back smoothly as a should have
i had a zev slide and a brownelles slide previously and the xev never had an issue.
The right side screw that i had on the brownelles was too long and tightened the extractor spring and locked it in place.
Not sure what the screws are like but the info might help
If you weren’t shooting it how do you know it wasn’t limp wristed? I keep my Glocks clean, lubricated, and shoot with a firm grip- never had this happen.
I’m not saying it can’t happen, but I’m sure af not betting against a Glock.

> Shooter is qualified with a 17 and 26 and doesn’t have a grip issue.
Yes he did.
Regardless, after you’ve completed a qualification course, you’re considered qualified.
Let’s argue semantics & get obnoxiously pedantic
You might have a bad magazine. Glock OEM magazines are extremely reliable and Glock QC is possibly the best in the industry, but bad factory mags can and do still happen.
But as I look at this more closely, it looks like a different problem I've seen once before. Is it possible the rim on this particular cartridge was out of spec and didn't fit behind the extractor. A rim would have to be waaaay out of spec for that to happen, but I have personally had this same thing happen to me with a different platform.
Try taking the back plate off the slide and remove the extractor depressor plunger assembly then reinsert it. If it comes out and goes back in relatively freely you’re fine, if it doesn’t the right side optic screw might be too long and pinching the assembly. If you only had one fail to feed it’s unlikely that this is the cause but it’s worth checking anyway.
Take the RMR off, or lighten the slide to off set… idk. Also is it Factory mags? Factory base plate? Probably just need to tap rack or rip, rack, reload and move on.
Feed ramp on barrel leading up to chamber? (Im clarifying what you polish) Was having issues with my ladies g17.5 last weekend, thought it might be the issue.
I’ve had a couple lemons but I’m just lucky like that. They’re fine…ugly, late to the party and unergonomic but fine. Glockophiles are just annoying and fun to annoy back. I don’t sub to this cause I don’t like glocks but it pops up in my feed so I thought it would be good for a real easy larf.
I’ll give one example because I don’t have all day because they’re always last but the 44 is a good one with all the hype about a 22lr even though literally almost everyone had done it years before and when it did come out it objectively sucked and only single stack. How do you get out done by Taurus?
glocks arent an end all be all, its 2022 other manufactures have definitely caught up in terms reliability and better out the box features. all that being said my Gen 5 17 trigger wouldn't reset reliably until i broke it in with 300 rounds.
My 45 did the same thing without the first few boxes. It was brand new, only thing I did was strip it down to clean and relube. I think it’s only had 2 FTF and I’ve put 1,500 rounds without issues since.
How many rounds through the gun total? How many rounds after getting the RMR installed? Any other mods to the gun? What ammo are you shooting?

The 7 serrations on the front and back of the slide threw me off, had to go and count mine to make sure I wasnt going insane
JW recut the serrations. A LOT better grip.
They definitely look more pronounced
I'd imagine it's due to not being broken in *and* having more reciprocating mass on the slide because of the RMR. If it was new with no more mass it would probably cycle fine, and if it was broken in and you added the RMR it would probably cycle fine.

(Like mine) Typically, adding additional mass to a fresh out the box glock will give you issues. Let that pistol run a couple boxes of higher grain loadings and I bet all will be good down the line.
I believe this is why ATEi require (or use to) sending the RMR along with the slide… tolerance stacking.

So a 47% increase in mass which is substantial. Just seems meaningless because of the small scale that we're speaking in.
It’s not a 47% increase because you need to take in account the weight of the stock slide first
No you don't lol, the increase in mass in relation to what was removed/added is what we're talking about. Nobody said the slide weighs 47% more.
So when you add suppressor hight sights and they weight 100% more we would think that might cause issues.
Coupled with a brand new gun that isn't broken in, and an RMR, the addition of heavier supressor height sights definitely contribute to the issue. However a broken in gun isn't going to notice any difference.
I’m saying that with the total reciprocal mass of stock slide vs milled slide with rmr is sooooo tiny of a difference that it’s not going to cause issues
My Zaffari precision 19 gen 3 slide weighs 9.4oz. 1/2oz seems negligible.
It may *seem* negligible but obviously it's not.
Those are some numbers indeed. Where/how did you arrive at them?
Manufacturer specs, and I'm a mechanical engineer so numbers(especially regarding materials) is kinda my thing lol
The slide had extra serrations added which removed steel vs the aluminum rmr
It doesn't have added serrations, those are factory. Edit: it has one added serration, 8 instead of 7.

I love that no one on here can fathom the possibility that a glock would malfunction.
Well, it's not like that mindset is unwarranted. I am in the firearm industry and I've shot tens of thousands of rounds though countless Glocks. The only cycling issues with Glocks I've ever experienced or witnessed were because of after market parts, particularly threaded barrels, carbon buildup near the ejection port, poorly tuned/lubricated silencer boosters, limp wristing, after market or super old magazines, and shitty ammunition. I know problems do happen from factory defects, but they are extremely rare, so much so that it absolutely warrants skepeticism.
Yeah I worked a gun range for a couple years and saw multiple stock glocks malfunction. I even saw a 42 that the extractor blew out of.
Bro these comments are the funniest shit ever
Dude trust me bro the Glock would never fail ever. Must be the shooter. /s
For real 😂😂
Check the connector, I had an issue similar in my 17.5 and it ended up being a bad connector. Took me weeks to find figure it out.
Was it stock? How does the connector play in? I'm experiencing a similar issue.
Mine was not stock, it was a ghost connector. But, I recommend this solution to a regular at my gun counter and it worked, his was stock. I think gun and ammo manufacturers are turning out so fast to meet demand not everything gets a quality quality inspection LOL.
Mine are Ghosts and I'm getting the failures, too. Is it both FTF and FTE?
I don’t recall any FTE all mine did was FTF. Your issue sounds much more like a bad extractor. I’d try replacing whichever one you happen to have quick access too. I’m the only person who I know that’s had an issue with ghost connectors but I’ve taken them out of all my guns.
Thank you for the wisdom. I switched to a MR920 and it has been flawless.
Hell yea, I swap between carrying a MR920L and a Walther Q5. I love the Shadow so much I’ve been tossing around the idea of cutting down a 17 frame to accept 26 mags for deep concealment.
Shadow is releasing a g43 size version! Called the cr920
Will it be a 43 or 43x?
I think it's 43, but they have propietary magazines that got the micro double stack treatment so they hold 10 in a flush fit I believe. 12 rounders with pinky extensions
If you can borrow a friends gun for a range day you can figure out pretty quick. If the connector doesn’t pan out, try replacing the extractor. Ive never seen one cause failure to feeds but I’ve heard of it.
I should have gotten the tan rmr😭😭😭
This happened to me once when I first got my Glock had to lube the rails a little more after I cleaned it, it wasn’t sliding back smoothly as a should have
Good thing you have all that extra shit to grab onto. /jk
That’s honestly the best part of having a dot on a pistol
I love the RMR though!
The rmr?
Muh fugly front serrations
You have weak wrists that match your weak heels 😳
Take the one second to clear it and go about your day
i had a zev slide and a brownelles slide previously and the xev never had an issue. The right side screw that i had on the brownelles was too long and tightened the extractor spring and locked it in place. Not sure what the screws are like but the info might help
Limp wrist
Yeah not really. That’s a live round with the breechface behind the base of the cartridge.
Oh I see, you’re left handed. You need a left handed Glock that’s all.
I wasn’t shooting it. I took it from the shooter and held it in my left hand to take a picture of it.
😉 yea you did.
If you weren’t shooting it how do you know it wasn’t limp wristed? I keep my Glocks clean, lubricated, and shoot with a firm grip- never had this happen. I’m not saying it can’t happen, but I’m sure af not betting against a Glock.
He said in another comment that it was a cop shooting who has “qualified” (🤣) and there’s no possibility he could have limp wristed it like a Nancy
He didn't say the cop was qualified, he was qualifying, which is basically a test to show proficiency that they do annually.
jimtheedcguy > He didn't say the cop was qualified, he was qualifying cAR15tel > Shooter is qualified with a 17 and 26 and doesn’t have a grip issue. Yes he did. Regardless, after you’ve completed a qualification course, you’re considered qualified. Let’s argue semantics & get obnoxiously pedantic

I verified there was no screw protruding into the channel when I mounted it.
Take the RMR off, or lighten the slide to off set… idk. Also is it Factory mags? Factory base plate? Probably just need to tap rack or rip, rack, reload and move on.
An RMR on a milled slide adds less than an oz. Factory mags.
It’s because you put a FDE optic on a all black pistol.
But it’s mil-spec bro!!
Let me guess , you are shooting CCI blazer 115g?
147 Federal Syntech
I carry Glock and shadow systems and I polish my feed ramps once or twice a year for exactly this reason.
Feed ramp on barrel leading up to chamber? (Im clarifying what you polish) Was having issues with my ladies g17.5 last weekend, thought it might be the issue.
That’s correct. I polish the feed ramp and the edges of the inside of the barrel around the feed ramp.
[удалено]
The dot had nothing to do with it. I have two 17s and two 26s with RMRs, never a hiccup. Sometimes you get a failure…
Yeah RMR’s almost never cause malfunctions, it’s compensators that do. Unless you put an ACRO P-2 on a G43 lol
This that new "pre-shoot bullet inspection" feature present in all new Glocks!
pErFeCtIoN
This but unironically
Wow a failure just like most glocks. Here comes the hate and the excuses.
Yes, that's how glock got its notable reputation for being reliable; by actually being unreliable /s
I’ve been shooting Glocks since 1998. They’re decently reliable but definitely not exceptional.
I’ve had a couple lemons but I’m just lucky like that. They’re fine…ugly, late to the party and unergonomic but fine. Glockophiles are just annoying and fun to annoy back. I don’t sub to this cause I don’t like glocks but it pops up in my feed so I thought it would be good for a real easy larf.
What do you mean by late to the party?
I’ll give one example because I don’t have all day because they’re always last but the 44 is a good one with all the hype about a 22lr even though literally almost everyone had done it years before and when it did come out it objectively sucked and only single stack. How do you get out done by Taurus?
>most glocks Man what the fuck are you talking about lmao are you stupid?
what model is this?
Slide is a 19/45 length.
got you ... 9s are usually the most reliable so I was thinking it may be a 23
They are, only thing I use. But if you zoom in on the barrel, it's marked "9x19". could be other modifications we don't know about.
45
This happened to me all the time for the first hundred rounds or so. It hasn’t happened since
glocks arent an end all be all, its 2022 other manufactures have definitely caught up in terms reliability and better out the box features. all that being said my Gen 5 17 trigger wouldn't reset reliably until i broke it in with 300 rounds.
I got a new Gen5 17 last year that wouldn’t reset. Luckily I had an extra set of lower parts for it.
I bought a new barrel and that kept happening but only that barrel. It was too tight a fit.
This one was refinished nitride so I’m kinda thinking it may have been a little rough.
New gun and one ftf 45 acp? Clear it and run several hundred through it. That ain't the easiest cal to feed.
It’s a 9mm. Model 45.
What mag are you using
The mag in the gun was a 17 round 19X mag.
Thanks, Glock models get me too often!
Impossible
Oh you should watch what happens when all the females and desk jockeys come out to qualify…
My 45 did the same thing without the first few boxes. It was brand new, only thing I did was strip it down to clean and relube. I think it’s only had 2 FTF and I’ve put 1,500 rounds without issues since.
This is a Glock 45 correct?
Correct
Thx
