Hello everyone! Hopefully this is the right place to post. Last year I bought a full-metal STI Off-Duty. It worked flawlessly and I was very proud of it, until it started shooting...by itself. The spring apparently fails to lock itself in place, and fires after 3 seconds of arming. I tried disassembling it, but there's no good I can do without help. If required, I will disassemble the gun again and show you some photos. Thank you for your time. Your help would be much appreciated.
