Thanks for the information, I guess I just gotta get a fs

If you decock and take off the safety the hammer is resting on the firing pin. With enough force or a drop it will go off. The 92s doesn't have a trigger block like the 92fs does.

Because I want no safety, I want ONLY decocker

I don’t want to draw it and have a fucking safety engaged and get shot, but I’m just used to glock

i own one its already a decocker, why install a decocker on a decock gun doesnt compute

I wanna buy one of the surplus 92S, can I install one of these on it:

If not, is there another option?

Can I install a decocker only on the Beretta 92S?
