It’s magnificent. Extremely accurate, and easy to shoot. The 5.5 lb trigger is pretty awful. 

The longer barrel doesn’t help velocity as much as you might expect, only adding about 100fps. But recoil is noticeably lighter than my 5-inch Colt Delta Elite, and I think it’s more accurate than the Colt too (perhaps attributable to the superior sights and longer sight radius).

It hasn’t proven 100% reliable unfortunately although much of the problem can be attributed to the factory magazines which seem to be junk. 

The cycling seems a bit rough when compared to other 1911s, even with the spring removed. After firing 150 rounds through it I found the cause—there is an occlusion on the underside of the slide, a casting flaw apparently. The disconnector rides up into it whenever the slide moves forward or back, rather like hitting a pothole, which slows the slide and creates malfunctions occasionally.  I think it needs to be TiG welded then machined back to spec and then it should run perfectly. That’s why I was asking what kind of steel is used—I was considering having a local welder/gunsmith try to fix it. But the more I think about it...
