Have one of these in mint condition. Looking for a source of mags. This pistol (based on serial number lookup on the internet) is a late model produced in 1919 and has the spur hammer and fine serrations on the slide. I've tried some mags from triple-k but even though they fit, one won't feed and the other won't load 10 rounds. Fortunately, I've got one OEM mag that works great (after taking it apart and putting the spring in correctly so the follower would move all the way up to feed the 10th round without jamming). Anyway, any help locating mags would be great! 10 shots quick is correct.
