Well as the title says i had put in an extended slide release on my brothers Glock 36. we went out to the range today and he was having problems with the slide locking to the rear like the mag went empty. kinda weird cuz it would usually do it on the 4th or 5th round left in the mag. i asked if he was hitting it with his thumb while firing and said no so i tried it and did the same with me and i made sure to keep my thumb off of it. Curious if anyone else had issues like this after putting in a glock extended slide release. Part was bought here in tulsa at ops. i had put one in my G19 and my buddies G19 as well never had any issues with either till now on my brothers weapon. Anyways any help is always appreciated!!
