I'm a new member and thought I'd spout out a little. I've tried all the new gizmos on the later versions of the M11 and except for newer sights don't shoot the old war horse any better than a standard M11A1. I like the old wide spur hammer and the arched mspr housing, and no guide bars on the recoil spring. It's fun to mess with all the improvements, but the standard configuration has never let me down. I guess I'm just an old fart set in my ways.
