want to put these adjustable sights on my 92a1 for CMP EIC matches

the front sight is supposed to be drilled and pinned on over the existing front sight, but i dont trust the drill presses i have access to to do the job properly. do you guys think red loctite and clamping it down until it sets would withstand the recoil? or at least not let it move so i can use the new sight as a jig to hold the drill bit steady and drill the holes exactly where they need to be? my drill has a tendency to walk until it gets into the hole then it does fine

I don't think those sights are made for your pistol.  The 92A1 has replaceable sights, right?

dovetail front and rear yes. ive seen the one beretta has on their website for the brigadier model but requires a taller front sight and i havent found where i can get those

You can order these at custom heights at very reasonable cost, or you can order a tall one and file it down to the height you want.

I have a Brigadier and this rear sight/rail for a FastFire II. I had to figure out height by try, file, try repeat until perfect.
