I finally broke down and bought the new M&P 9L PC ported. I really like the gun, it's very accurate and the new triggers feel great! No need to Apex anything. Problem is...it works great with my KKM non-ported barrel, but has at least 4 or 5 jams per mag with the OEM ported barrel. AAA 115, 147 and my local reloader's 124's. It extracts and ejects the empty case but the next round gets hung half way into the chamber, at a slight upwards angle, with the next round in the mag slightly forward and touching the rear of the "almost" chambered bullet. I have to pull the mag to clear.
Has anyone else experienced this with the new PC ported? Thanks for any feedback!
