Just picked up my first 1911, the new Nightmare, and I'm having an issues with I think the mag. When the mag is loaded up with 8 rounds it won't lock into the gun, it feels like it's hitting something. If I lock the slide back the mag will then lock in but slide jams up with the first round when released. Now if I only load up 7 rounds in the mag it works flawlessly. Has anybody else had this issue? Could this just be an issue with the mag guide spring being too tight with 8 rounds? And will it loosen after some break in? Or is their something wrong with the mags or gun? This does occur with both of the factory mags I was given. I haven't had the gun to the range yet. I have done a tear down on the both mags and cleaned and oiled them up with no change.
