Rear Ameriglo Suprressor height sights keep shifting right

[ForestGump]

Every 1000-1200 max they shift right third set I’ve had pressed on and replaced at

Primary arms Glock 34 gen 4 MOS 

Any help is more than appreciated last set was red loctite

Red loctite where? Make sure you degrease dovetail and sight before loctite. Does rear sight press in dovetail tightly, it should. Red loctite the sight in the dovetail and set screw.

If your sight fits tightly enough it needs driven in with a punch / sight pusher... you use brake cleaner to degrease the dovetail, sight, setscrew hole, and set screw... and you coat the dovetail and the setscrew with red loctite then install and torque it?

 

You should never have a sight shift. I never have. True of my installs on Walther, Glock, M&P, or Tanfoglio.

 

(You are removing the setscrew, aerosol-blasting the threads on screw and sight, and reassembling with loctite, right?)

Ameriglo suppressor height rear sights dont have a set screw.

 

I have had three shift in their dovetails.  All three required a drift punch in order to be installed and some pretty stout hammer blows.  I think the metal is just soft...

Ameriglo sights are very soft. You might try peening the bottom or use a punch to create a little extra material on the sight.
