I can't reliably lock the slide back on my G-36 using thumb pressure on the slide stop tab. The stop barely catches on the slide. An empty mag operates the stop fine though. I see what is happening. Thumb pressure on the slide stop tab pushes the rear edge of the tab against the frame. Then the upper rear corner of the tab catches on the lower outside edge of the slide, preventing the slide stop from moving completely up into place. It appears that the tab of the slide stop is not perfectly parallel with the gun, causing this problem. Is that normal? Maybe the stop got bent a bit at some point? How hard is that metal? Could I perhaps bend it back a bit? Edited for correct terminology Wanna kill these ads? We can help!
