Sight installation

Hey all,

I'm getting ready to install a set of Ameriglo sights on my Glock 19 and need clarification on a couple of points.

First, given that I can't find a 60 degree 3-corner file anywhere in the greater Seattle area and Brownells wants $50 for their proprietary model, is it an acceptable method to remove material from the bottom of the dovetail if fitting is required and not the angled part of the dovetail?

If yes, what is the best type of file to use? Fine, coarse, bastard,etc? I'm assuming fine to control the amount of material removed, but I need clarification.

Right now, the rear notched sight pushes in about 40% of the way by hand, which I think is close to being read to drive in. I have non-marring punches, but no brass/delrin hammer. Should I go ahead and try to tap it in, and, if yes, how much resistance do I need to feel before deeming it too tight to go any further?

Anyway, thanks in advance for any info.

DO NOT touch the slide dovetail.

Or the V's of the sight dovetails.

All you need to do is file the flat on the bottom of the sight very slightly to lower the sight V in the slide dovetail.

Any flat file will work fine, unless the sight is too hard to file.

In that case 'sand' it down on a peice of emery paper on a flat surface.

I would grease the dovetail and try tapping it in.
If it won't go, Stop and remove a little more off the bottom of the sight.

Too tight my gall the dovetail and basically weld it in place.

Don't put all your eggs in one basket.
Or all your primers in a glass jar!
