TL- I have loaded everything from 1-5 rounds in the mag and none work. I am shooting Fiocchi 93gr round nose FMJ ammo. When it does not feed it is in a "stove pipe" position. At times the empty casing is actually stove piped so the next round does not have the opportunity to load. I see nothing that would stop the round from properly chambering so maybe the magazine is the issue. After disassembling the pistol I completely removed the firing pin housing from the upper frame, I put a round in the firing pin housing to see if the ejector had enough strength to hold the round in place, it works fine so the ejector spring is not the issue. As I mentioned earlier I completely disassembled the pistol, cleaned it thoroughly, lubed it and put it back together. I did not fire it before cleaning and to my knowledge my Dad had never fired it.
