I like the Springfield Operator and it can be optioned with the slide milled for an RMR red dot. If you prefer a 1911 IMO this is the way to go. However, if you're open to options, the Springfield XDM OSP 10mm with the threaded barrel is a good choice, it's every bit as accurate, as my 1911s, at least mine is and I have the option to shoot suppressed. It carries well in a Kenai Gunfighter chest rig.
