I had a 21A inox that I got from a guy for super cheap because the slide had locked up. The pin holding the ejector had backed out into the rail the slide rode on, and wouldn't let the slide come back all the way. I had to play a game of operation with a tiny little flathead and slowly work it back in just enough so it could be disassembled. Once the slide was off I removed the pin and put a little blue locktite on it for retention. Never had a problem with it afterward for about 500 rounds until i traded it off. It was quite literally a blast to shoot with CCI stingers. Fun gun. Would love to have another like OPs set up.
