How do Glock 17 mags and HK USPf 9mm mags compare in length and width? Height is not a factor. I have the USPf9 mags but not the G17 mags. What I really want to know is if I can buy the model specific G17 kydex mag carriers and expect my USPf9 mags to fit with possibly the help of adjusting the retention screw.
