I recently added a S&W M&P9C to my collection and one day while cleaning my firearms I noticed something interesting. The MP9C barrel fits and locks up inside of my Glock 23 Gen 3, with the Glock recoil spring. With my .40 cal mag, I was able to to cycle 9mm snap caps fine. The barrel is too short to protrude from the slide but it looks like it sits at a good angle so none of the 9mm rounds wouldn't interfere with the slide/barrel clearance. My question is would be possible with live fire? I don't have access to land so I can't really test this. Let me know what you guys think.
