I cannot get all 10 rounds into my G37 magazines and when I do, I either can't load them with the slide closed or they cause malfunctions. I just finished an 8 hour handgun class where I shot over 400 rounds out of my G38. As long as I only loaded 9 rounds in my G37 magazines, all was fine. When I forced the 10th round in and tried it, the gun jammed up bad. Is there anything I can do, other than add mag extensions, to fix my magazines? Anybody else experience this? For the record, the standard G38 eight round magazines all functioned flawlessly with 8 rounds in them.
