We have a Glock 27 that we got because it was one of the couple pistols that fit in my wife's hand, and we like Glock. Well, that .40 has a real jump to it which neither or us like but we could shoot ok. So, we decided to get a 9mm barrel from LW and a mag extender for the 9mm mag to see if that would help control, and boy did it. It feels MUCH nicer to shoot. The problem? Every round was either FTE or FTC for her. Was fine for me. We got a trainer over and asked for grip tips and he spend a half hour or so with her getting her stance and grip and everything right and by the end she was shooting really well, hitting within a few inches of the x (3 yards), holding strong, but still FTE or FTC. Trainer shot and it was fine. By the end ONE round shot and chambered well for her, then the last ejected BUT the slide didn't lock open.. It was out of rounds. This tells me it's not traveling all the way back for whatever reason. The trainer and I aren't sure what else to tell her, she was trying real hard, and as far as he could see had a great stance and grip. He appeared really knowledgable and experienced to me.. Is practice the key, or is a slightly lighter spring the ticket? In a real world situation where she might need it I'm not sure I foresee a super proper and strong grip and stance and focus getting put in place before she fired something off, but I darn sure want the next round to load. Thoughts? Can I even get lighter springs for factory rod or would I need aftermarket? Thanks for any insight.. Edit.. Meant to mention, we didn't return for a 26 because I wanted the .40 option. Still do, but I'm not completely opposed either..
