I have had my R1 Enhanced for about a year. Great gun if you like the enhanced features - fibre optic front sight, adjustable rear novak, extended mag release, extended thumb safety, and checkered mainspring and grip safety bump. 2 8 round mags.
As far as craftsmanship, you have 3 choices for American made 1911s for under $1000 - Ruger SR1911, STI Trojan, and Rem R1. I own an SR1911 too and IMO the Ruger is a better deal being stainless. Please note I have yet to shoot my SR1911 so I can only compare build quality and finish. If I can recall, the Ruger is tighter slide fit than the Rem new. After about 1000 rounds the R1 still feels the same but smoother. R1 trigger feel is better and lighter even as series 80 vs the SR's series 70. The SR's is slide is tighter and not as smooth but that may be lack of wear.
I really like the R1 Carry 5" but for the money that is Kimber territory from a mass production company, not worth it IMO.
