Sometimes when I shoot my STI Trojan, 45c. the slide stop migrates to the left. This a small amount of movement but it is noticeble. This causes the magazines (Wilson and McCormick) not to drop when the magazines release is depressed. Additionally, it sometimes causes the slide to freeze mid-cycle.
If the slide stop is push back in, the slide will move and/or the magazine will release.
Any ideas on what is causing this problem?
Thanks in advance.
