I have 1911's by Colt (two NRM Series 80 GM, a Series 80 Officers Model, Series 70 Govenment & Gold Cup and a pre-series 70), a Kimber Compact Custom (pre Series II), a heavily customized Springfield, two Wilsons (1996A2 and CQB) and a Les Baer TRS.
One of the Colt S-80 Gov't needed work to make it run, the other was great (reliability, trigger, accuracy) OOTB. The Gold Cup has never failed, all it shoots are low recoil LSWC target rounds. The Series 70 GM shoots 230 ball only. The Kimber Compact has never malfunctioned. Neither of the Wilson guns has malfunctioned ever. The LB TRS failed to feed twice in the first 200 rounds, but has been perfect since that first range session -- I stopped counting.
If I needed a 1911 of the shelf right now, I'd probably go with a Colt. Preferably a new Series 70. Being in CA, I'd get a new Series 80.
That said, I use a Glock for PD and a Rem 870 for HD.
