I recently bought a very well worn FEG p9m on impulse. Paid very little for it and knew nothing about them other than it resembles a hi-power. Upon doing some research i discovered some are closer to the hi-powers than others and some might use a S&W mag instead of a browning mag. Does anyone have any experience with these or a hipower mag i could test fit in it to see before i buy a spare? Any info is greatly appreciated. Thanks.
