Hi! I come here because I identified a problem with my Glock G23 but I don't know how to solve it! What I have seen: -I removed the slide and the magazine, I put the hammer in the "armed" position by hand and I activated the trigger. The hammer moved well and the valve knocker gone into the magazine hole perfectly. -I removed the slide and load the magazine with some gas. As before, I put the hammer in the "armed" position by hand and I activated the trigger. The hammer moved again well and all the gas was blown out which is a good thing. - But when I put back the slide and I try this, nothing happened ! I removed the magazine to understand what happened. In fact, when I activate the trigger, the "sound" of the hammer release is lower than without slide and the valve knocker does not go into the magazine hole as it should. I hope that my description is enough precise for you to help me. Thank you in advance for your help!
