some problems....
I shot the SR1911 for the first time this past week and at first I thought that I was having major problems. After firing off 2 rounds, the gun jammed with a round not quite seated in the chamber and the loaded mag would not drop with the release. After fiddling a bit, I pulled the slide back some and the mag dropped (with the release) and when I racked the slide, the jammed round dropped through the mag well. I tried again, using the same round (I know) and repeated the same problem. After clearing it again, I put a fresh round on top. The mag would not seat (just kept sliding down.) I worked the release a bit and it finally grabbed. From that point, I put about 135-140 rounds through it without a hitch - some rapid fire.
The gun is pretty accurate - as much as I am, so I was not disappointed. In hind sight, I probably should have cleaned/oiled it before shooting it for the first time (I shot it right out of the box.)
I will continue shooting it with each range visit (about every 2 weeks) and will report back in the future (good or bad.)
