I'll chime in here as an E-Series owner. First, it has been boringly reliable with everything I have loaded for it, HP, hard cast, FMJ, various profiles. It will feed empties. Accuracy is on par with other factory offerings, being limited by the stock trigger among other things. I paid under $760 out the door back in March. That's the good.
Some of the (personal) bad: the frontstrap isn't fully profiled. Checkering is nice but was not fully cut to the radius of the grip leaving a squarish edge. Not problematic or uncomfortable but noticeable. The thumb safety is a tad on the narrow side and was slightly bent causing contact to the plunger tube. The factory trigger was noticably heavy with a fair amount of creep. Factory springs were both heavy and sub-standard in quality. After a professional evaluation the following was found: SS pin was undersized and not consistent in diameter leaving little to no lower lug engagement. Barrel bushing fit was loose (I could turn it by hand easily).
Even with a new bushing, slide stop, thumb safety and ignition set it will come in at close to the $1,000 mark which will make it a reasonably low priced, reliable and accurate shooter. I'm not disappointed in my choice but do agree that a nice Colt, Dan Wesson or Springfield could have been had for even money and likely "more" gun. I will add my Colt XSE is also receiving a new bushing (factory was just snug), thumb safety (replacing factory ambi), slide stop (for personal preference) and beavertail (factory was poorly fitted). The smith involved is a 1911 specialist with more than 25 years experience including working for several big names in the 1911 world.
A quick pic to make up for my lengthy post.
