I use the Wilson 38 mags for my 9x23. I can get 10 rounds in but that last one is a real bitch. The guns reliability suffers because of the pressure that 10th round puts on the slide.As the spring wears down a bit it gets easier but if you shoot IDPA and have to do a tac reload you have to hit it with a sledge hammer to seat the mag against the pressure.Have fun.
