Hi, excuse the first post being a plea for help, but there it is. Bought a .25, took to the range today. Shot exactly two rounds. Gun quit. Background: bought online, barrel has very well defined rifling, frame and slide a little surface rust but even the factory plastic grips are not cracked, so pretty nice shape. Gun came with what I am sure is an aftermarket magazine because not one color variance, scratch, nothing, on the magazine. Taking the mag in and out is a little more difficult than I expected, and just the way it fits and how the rounds act, it has to be junk. Anyway, I am open to hearing from those who know. Any reason this highly thought of pistol should have jamming issues? Magazine likely culprit? I am hunting for a factory mag, have located what I think is a source. Thank you sincerely in advance for your time and knowledge.
