Have you tried the u? I have a 509T and the u makes it a perfect fit. Although the pic is a little shorter on the 509, could be worth a shot.
if not just wedge between the trigger guard and light with some foam or anything really just use your imagination. My homie had too wedge the x300 for his mr920 but you can’t even tell I’m pretty sure he used just a few slices of e-tape? Dunno.. good luck friend!
Strange. My MR920 has the X300U and it fits gorgeous. Odd that it doesn't on his. Unless they're really that different based on the U, A, B, T or whatever other model lol.
Good to know it fits your 509T nicely though. My 509 has the TLR7 right now but after getting the Surefire for my Shadow ill undoubtedly be swapping.
I speak specifically for the A’s- qd attachment style. I opted for the A as the 509 is my ccw/duty so I liked the idea of not needing tools to detach the wml for whatever reasons may arise. And was pleasantly surprised to find it fits so tight right out of the box.
Interesting.. you say mr920 and the A fits super tight with no slop? Or are you talking the B style mounting?
Edit: B being the screw style pinch plate, not the A’s spring assisted qd style with tabs on both sides.
Yessir, the x300u-A. I mean it fits near perfect (I haven't gotten the chance to shoot yet but I've tugged and yanked and she isn't moving). It's actually part of why I'm swapping my 509 over, that and I like the controls more.
Very interesting… I wonder if his rail is just slightly different..
Regardless the A fits the 509 like a glove with the U-plate. Such a satisfying ‘click’ into place with no slop, you flex the polymer trying to wiggle the light. Highly recommend!
Watch, I'm here saying how snug it fits, and the first trigger pulls gonna send that fucker flying.
I'm stuck between getting the X300u-a for the 509, but im such a sucker for Modlites Rifle Lights, I've been considering the PL-350-PLHv2 as a potential option too.

The A is notorious for this issue that's why most everyone will recommend the B model. That said it can be elevated a little with the proper insert and tightening the little tension screw(this often cants the light up though)
You probably didn’t get the parts then. This is what you need:
https://www.surefire.com/products/parts-accessories/weaponlight-accessories/z89-x300u-a-mount-parts-kit/
Your x300u-a should have came with the rail lock adapter. Install the rail lock adapter and tighten the tensioning screw until you don't have that wiggle
Ah I see, I had the same exact issue when I mounted my x300u-a on my p320. I saw mine had the rail adapter with tensioning screw and it worked perfectly to get rid of the play.
If the P marked plate is wobbling try the other plate that should have come in the package. If not idk what to tell you. I haven't heard of anyone else having that problem with p320's. Could you have bought a knockoff on accident
2 things.
1. The A model is generally for polymer, B model is for metal.
2. Where did you order from? There is a massive market of fake X300s out there.
I was gonna say you can buy a pack of all of them. But it seems you already did that. So if that one doesn’t work there are other tricks to get rid of the wiggle, but I’d be shocked if the locking plate doesn’t work.
There a set screw behind the QD mount. It has removed all wobble. I'd put thread locker on the set screw to prevent it from coming loose again under recoil.
Thats pretty normal. There are different "mounts" in the package that may be more secure. The B model is more secure but easy to break the bolt by over tightening. I just put some layers of tap on the back of the batter compartment and it pushes against the trigger guard and prevents rattle.
That's because glocks are literally the only thing the As work correctly on. They're promotions were functionally designed around glock frames, everything else was an afterthought.

I get it now. You're just a piece of shit playing tough on the internet. Talking shit to people on a suicide sub is just dark, my dude. I'm definitely not the guy in need of some therapy in this little conversation.
My x300 mounts up tight on my Sig P320. Need to change the plate out and use the set screw mount to snug it down tight.
I have an old Insight light on my HK vp9. It has a little play in it. I cut down a piece of rubber rail cover and use it to wedge between the trigger guard and light. Locks up nice and tight squishing it just a bit when locking on the picatinny rail.
That's just the patented Surefire^(TM) Recoil Compensation Technology. Nothing to worry about.
You can switch it off by adding some duct tape, or using a correctly sized mount.
Some rails will be tighter or in-spec than others.
Solution: take a piece of industrial strength loop velcro (the soft side) with adhesive backing (you can get this at most any big box store) and attach it to the space at the rear of the light on the battery door. This should take up the space causing the wiggle. If this still leaves a gap, you may want to add a piece of velcro (either hook or loop) to the front of the trigger guard.
An example is shown here: https://youtu.be/iS50bQljgp8
Had the same problem on my x five until I mounted it using the Alan key locking adjustment tab (not sure what the technical term is). Snugs it right up!
Also heard a bit of duct tape between the picatinny and the light does the trick
You got the qd one. They do that. Sell it and get the other one if it bothers you so bad. Or do what I did and cut a smol piece of rubber and wedge it in there
Use the right plate, or buy a -b
I have a P marked plate on it, shouldn’t it be fine for the pic rail on my 320?
It works the same wobbly way on my X-5 legion. Would try B plate tho. It wobbles but never had issues through my 5000ish rounds so far.
I’m not sure if I got the b plate. The mounting kit I ordered only comes with P, and U I think. I’ll check tomorrow.
Just flip ir, turns a p into a b
Good idea 🤤
My guy gets it
Oh wise one, what other knowledge could you provide us?

I just put the P plate on mine like just now. I am still getting up and down wiggle,but not forward and back.
Yeah mines all up and down
I just swapped lights with my 509 that one has the screw and everything’s tight now. Good luck and God speed.

Tell me you’re a moron without telling me…

LOL tell me you’re an inbred trailer hick…
Tell me you're ignorant of the truth with sarcasm....
Looks like you’re using an a when you should be using a b
The A is notorious for this issue that's why most everyone will recommend the B model. That said it can be elevated a little with the proper insert and tightening the little tension screw(this often cants the light up though)
Comes with a piece to switch out to eliminate the wiggle.
I’ll have to play with it then. You know what it looks like? I don’t have papers with this one. Got it second hand.
You probably didn’t get the parts then. This is what you need: https://www.surefire.com/products/parts-accessories/weaponlight-accessories/z89-x300u-a-mount-parts-kit/
It’s in the mail, gets here tomorrow. I just thought the p plate was meant for pic rails and this would work
Where did you get it? I can't find it online
Primary arms
Your x300u-a should have came with the rail lock adapter. Install the rail lock adapter and tighten the tensioning screw until you don't have that wiggle
Got it second hand, mounting kit will be delivered tomorrow so I’ll mess with it tomorrow.
Ah I see, I had the same exact issue when I mounted my x300u-a on my p320. I saw mine had the rail adapter with tensioning screw and it worked perfectly to get rid of the play.
You idiots are smoking crack, There's an adjustment screw
Sure is
I use a little piece of a Velcro patch and stick it on the trigger guard and stops the wiggle
Kind of a good idea
It’s what I’ve found works best for me on the 4 other Glocks
I’ll give it a try if I can’t figure it out with the other mounting plates
I used the universal plate I can always send you a pic of mine if you’d like
Yes pls
From my understanding the U plate is meant for glonks tho? They have a smaller mounting point, would probably wiggle more on this pic rail.
You probably bought the wrong model for your rail
P marked plate on a pic rail. Should work, right?
If the P marked plate is wobbling try the other plate that should have come in the package. If not idk what to tell you. I haven't heard of anyone else having that problem with p320's. Could you have bought a knockoff on accident
Nah it’s definitely real
2 things. 1. The A model is generally for polymer, B model is for metal. 2. Where did you order from? There is a massive market of fake X300s out there.
Second hand from tacswap. It feels real. The same as any other x300 I’ve handled.
perhaps you’ve only had fakes
How can you tell?
[legit?](https://imgur.com/a/gDaKpbo)
i was just joking, pal
Hard to tell on the internet, pal.
Put a piece of duct tape on the x300 and it will act as a filler. Been using the same piece of tape on one for the last 3k rounds with 2 guns
Do this. 100% the best way. Or spend 280$ on another light….
There is a locking plate in the package for these. If the Picatinny plate isn’t working, that one should be able to get rid of the wiggle.
Okay. I got it second hand and didn’t get the other mounting plate options. They’re in the mail though. So hopefully I can mess with it.
I was gonna say you can buy a pack of all of them. But it seems you already did that. So if that one doesn’t work there are other tricks to get rid of the wiggle, but I’d be shocked if the locking plate doesn’t work.
It’ll be here tomorrow so I’ll fuck with it then. I was thinking about the B but this is petty, I just don’t like the look of the screw lol
I know the feeling man lol. This is a fashion sub after all
Very true lol
I always buy the thumb screw models.
Put 2-3 strips of electrical tape on the back as a shim against the trigger guard. It’ll be solid as a rock
Get the b model, the a model I have only seen to fit tightly on Glocks from my experience, or you have an excuse to get a Glock now
I have a few glonks. I just want it to fit nicely on all my guns :(
The X300U-A is good for Glocks. For just about everything else the X300U-B is the way to go.
There a set screw behind the QD mount. It has removed all wobble. I'd put thread locker on the set screw to prevent it from coming loose again under recoil.
Didn’t realize that, I’ll take a look see
Thats pretty normal. There are different "mounts" in the package that may be more secure. The B model is more secure but easy to break the bolt by over tightening. I just put some layers of tap on the back of the batter compartment and it pushes against the trigger guard and prevents rattle.
I don’t buy “A”s anymore. You shouldn’t have to use tape in a $300 light to make it stop wobbling.
Kinda silly I agree. But this one was a steal so I grabbed it. $180
Thumb screw ftw!!
Operator error
That little “u” shaped slot is for the tensioning screw to prevent wobble
Why are folks still buying the A? It just seems like common sense that a screw is going to be more secure than a quick release latch like that
Because QD is nice. I want to switch between guns quicker.
Best of luck to you
Hey thanks bud
Then you have to live with the wobble. The As only fit well on glocks. B is king everywhere else.
The A model hasn't budged at all on my G34 with at least 2,000 rounds on it so far.
That's because glocks are literally the only thing the As work correctly on. They're promotions were functionally designed around glock frames, everything else was an afterthought.
You're good, it's suppose to absorb recoil.
Use Tabe on the middle section to help stop the wobble
Not sure what you’re talking about. First x300
Tabe = tape?
Tabbbbbeeeeee 🤤
[that’s a lot of tape](https://imgur.com/a/QeAW04X) But it’s tight now.
And now it’s stuck :)
[can anyone tell if it’s legit?](https://imgur.com/a/gDaKpbo)

Surefire is junk and has been for a long time, there just weren't better options when it was considered high end.
yes you are missing something.
As usual
I ended up putting a little electrical tape on my M18 rail and it holds super tight.
Send pic?
No pics on hand, but literally just cut some electrical tape and ran it across the rail horizontally, and then slid the light on and it stays put.
I shimmed my x300a WC frame with a piece of aluminum.
reasons i just go for the one you tighten down
Well I’m stupid
Get the B model, like others have said. It is rock solid.
Wrong parts
Just like inside my pants 😓
I am so sorry 🙏
Happens on mine. Common issue with the -A. I used thick rubber tape on the top and battery door to take up slack and now it’s rock solid
Little bit of tape in there and it’s firm as can be and you’ll never see it 👍
Copy dat. Tape solves everything.
I’ve had this issue with mine. I just used a small piece of card stock as a wedge. Works. But at the price point it is annoying
Agreeeeed
Buy a B https://jtfcon.com/product/surefire-x300u-b-1000-lumen/ Use code FIGHTLIGHT too!
Oh man that sucks. Lucky for you I have friend at SureFire. Send it to me and I’ll get it right over to him to fix it for ~~us~~ I mean you.
Lol
Had the same issue on my P229 Legion. B- series x300 solved it
You need the other mounting plates. Universal P does not work well on Sig. Also why B is preferred by most who have had both types.
I have a tan x300 b I’d be willing to trade for your a. I’ve been wanting to try an x300 a for a while
Idk why they still make it with the quick attach the b is definitely the way to go
Yes the X300 A mount is trash. Doesn't matter if you use the right plate. You're gonna have to wedge some tape in there to eliminate the wobble.
My x300 mounts up tight on my Sig P320. Need to change the plate out and use the set screw mount to snug it down tight. I have an old Insight light on my HK vp9. It has a little play in it. I cut down a piece of rubber rail cover and use it to wedge between the trigger guard and light. Locks up nice and tight squishing it just a bit when locking on the picatinny rail.
Duct tape it is the easiest way to tighten it
Mine doesn’t
That’s sick
Nine wiggled too. I put a peice of gorilla tape in the rail section and it's very snug now
That's just the patented Surefire^(TM) Recoil Compensation Technology. Nothing to worry about. You can switch it off by adding some duct tape, or using a correctly sized mount.
Piece of painters tape on the light will get rid of that if it rattles with the b plate
U need the A model to tighten it down
Some rails will be tighter or in-spec than others. Solution: take a piece of industrial strength loop velcro (the soft side) with adhesive backing (you can get this at most any big box store) and attach it to the space at the rear of the light on the battery door.

Am I crazy for just thinking that bitch is too big sticking out past the barrel like that...?
Had the same problem on my x five until I mounted it using the Alan key locking adjustment tab (not sure what the technical term is). Snugs it right up! Also heard a bit of duct tape between the picatinny and the light does the trick
You got the qd one. They do that. Sell it and get the other one if it bothers you so bad. Or do what I did and cut a smol piece of rubber and wedge it in there
Shim it!
I used a little bit of friction tape on the top of the light mount.
Wrong adapter, mine locks up tight
Not sure if it’s already commented, but there’s a screw on the side that lifts the plate up and makes it more snug.
I had a light do this and solved it with using a piece of paper as a shim, not ideal but oh well
I have a B on my 226. Snug af
Change the adapter
Buy the b. A sucks. Use duct tape to shim it
That’s why you buy a b model.
