Glock MOS gen 4 models

[crinko]

I was thinking about getting a G34 MOS and putting a Trijicon RMR on it but I’m hearing mixed reviews on them. I hear good things and then I hear how there isn’t really that much material in the slide to hold the RMR on with out tightening it back down after a few hundred rounds, does anyone have a MOS model that could ease my mind or help me out before I go out and spend the money !!!!!!!!!!!!!

There are tons of MOS Glocks out there.

I personally bought a Brownell's RMR cut slide and it works great with my RMR. I never owned the MOS, but plenty of folks do and I haven't heard of any issues.

Blue lock-tite. I have a g34 gen 5 mos and don't have any issues with RMR loosening up. I've never heard of this being a problem on any of the mos glocks.
