Para Ordnance P14 or Armscor Rock Island Armory 1911 A2 14 RD .45 ACP Mec-Gar MGP144514AFC

Excellent! Works with my K2/.45 (true - slide does NOT lock open on last shot). Tough! Unlike stock mags, you can actually load 14 Rounds by Hand. Granted, you have to push HARD to snap fully loaded mag into place, but 13 rounds is easier. Stock mags (brand NEW mags - brand NEW gun) it took a Mag Loader to get 14 rounds in a mag (and sounded like the damn spring broke loading the 14th round). IMPOSSIBLE to get a 14 round Mag to load in the gun. Stock mags I have to only load 12 rounds to get them to load by hand (and easily load into the gun). NO FEED JAMS! :)
