I put 200 rounds through the Tisas 1911 this morning. I used 230 grain Winchester FMJ in the white box and didn't have any malfunctions. I had four 8 round magazines, the one Tisas supplied, and three Promag 1911 ACP mags. I thought the Promags didn't fit at first because they were really tight. I cycled them about 20 times apiece and they developed wear marks on the to corners of the mag and loosened up quickly. I really like the gun -- as I said, its my first 1911 and the trigger is better than any of my striker fired 9's.
The trigger breaks consistently just over 5 lbs and has a very crisp break. It was so good, the first few magazines I fired with my Springfield XDS 9 was all over the place.
Here are the first three targets I shot from 7 yards. There are 16 shot at each bullseye. I'm a competent shooter, but I wouldn't consider myself an expert by any means.
Here's the first two magazines with the XDS9, also 8 round mags.
Here's the sixth magazine for comparison. It was a 7 round magazine and I'm sure the flyer is my fault. It too me that long to get used to the Springfield trigger after the Tisas. I'll shoot the other way around next time.
