I believe I saw an semi-automatic pistol at a recent gun show and am wondering if anyone has any information as to manufacturer, reliability, availability etc.? Have been under the impression that this cartridge in an auto pistol had proven unreliable. Seems that this one was made by Auto-Mag but I am not certain. Thank you in advance for any and all information.
