I have several - 226, M11-A1(repackage 228/229), 1911 RCS Sport(commander size) and just purchased a 1911 Fastback(full size).
Depending on what you want it for - 226 is very good - used as a range gun, night stand and training.
For EDC, I alternate between the M11 and the RCS Sport.
The Fastback will have its first range trip this weekend.
All are more accurate than me. As for round count, probably 5,000 +- in the 226, around a 1,000 each in the M11 and RCS. Multiple brands of ammo, cheap target/plinking stuff and more expensive defensive stuff.
The only problems I had with any of them were with the SIG magazines for the RCS, fail to feed, which I think is due to weak springs, using Wilson magazines, no problems at all.
