OK, just bought a new in the box Combat Master Detonics in 45 acp stainless, took the new gun out to the range today, loaded the two ss six shot mags (both original detonics mags). inserted the mag, loaded one in the chamber, fired it, the gun jammed! It would only extracked the round out half-way, after looking the problem over, it seemed like when the empty case was being extracted, the the case would rub up on the next round in the magazine and get stuck on the rim, both mags did the same thing, Are thier replacement mags. Please Help.
