Will the screws used for a fixed mount .22lr rifle hold up under the stress of a slide mounted sight...would hate to have the screws sheer of and send the sight flying, not to mention the mess it would make of the holes.

I have no idea
Would'nt use this stuff on any project of real importance -
The little 9x18 has some recoil of course but not harsh.
Just something to do with extra parts on these cold days

They seem to be good quality screws and big enough they just do fit the holes on a set of weaver scope bases I had on a hot loaded 30-06. I realize that's not the same stress as on a slide mounted sight but I doubt the screws on most custom sights are any bigger/stronger.
