When I picked up my Five Seven I switched out the Glock mount on my Surefire X200B (which was pre-installed from the factory) for the picatinny mount so that I could use the light on my Five Seven. My X200B however will not lock into the second notch in the Five Seven’s picatinny rail forcing me to use the first notch. Having to use the first notch places the light too far forward for me to comfortably turn it on. I’ve seen other pictures of people on here with this same setup (Five Seven with Surefire X200B) and their lights mount right up against the trigger guard like it should. What am I missing?

Thanks, Dan

Do you have a USG or IOM FiveseveN?

 

[Dark Tranquility]

The USG I beleive. It'sthe one you see for sale everywhere these days. I just picked it up NIB a couple months ago when FN offered the 200 free rounds.

Thanks, Dan

I just tested my X200B on my USG.
Use the factory installed Glock mount not the picatinny mount.
For some reason the USG will not work with a X200B with the pic mount.
IIRC the rail on the USG was slightly altered from the IOM.
I know this because certain lights will work on one and not the same on other. Its the same way with all my IOMs and USGs.

Its also the same with the X200A and a USG.
Use the factory installed Glock mount (marked "U") and not the picatinny mount (marked "P")

BTW: The Surefire X200B is my favorite light for the FiveseveN. Its as bright as the X300 and unlike the X300 (which is longer than the X200) it sits flush with the end of the barrel.

I am in the same situation...so whats the best light (fit wise) for the Five Seven IOM?

 

[tqtran]

"Fit" wise for an IOM, it would have to be the Surefire X200B using the factory Glock/Universal mount ( marked "U" ). The X300 is a great light bits its rather long.

 

[tqtran]

Here is what I mean when I say the X300 doesn't fit flush with the end of the gun. See how when it is attached, the X300 sits out further than end of the barrel. The X200 sits flush at the end.
X300

X200

Don't mean to diverge the topic - but I had a question about the X200...

Does it slide on like an M3 light? Or, does it have the screw on 1 side likke the TRL1?

I wouldn't mind having 1 for my 1911 - but I didn't want to scratch up the finish by sliding it on and off. It is my understanding that with the TRL1 - you can put the light in the right spot - and then tilt it into place and then use the screw to tighten it to the rail... Does the X200 work the same?

Surefire tac lights slide on and off like a M3 but a little more snug.
After a while its enough to strip some coating off of one of my PS90 rails, if that helps any.

I do like my m3 but it look like you have a very nice Tac light! :?

Ok, never mind then. I'd have to get a TRL1 then...

Surefires slide on better than M3/M6 because the have a center feed ramp to help with the side rail feed channels. Thats why it fits more snug and secure but also why it wears on the rails more.
