I have a100% bone stock 45 acp Springfield 1911 Milspec (NM prefix), and it plops (5) 200 grain flat base SWC (SAECO #69) bullets sized at .452", 4.0 grains of Bullseye, .470 crimp, into a ragged hole at 50 feet/17 yards (2 hands rested, indoor range).
RANGE REPORT:. Range report: 1911a1 SA Milspec - 1911Forum

If you CALL Springfield Armory, and ask them about the milspec (and if it received any special "fitting"), they will tell you, "NO, it is a production line firearm, and does not receive any special fitting, parts, or extra attention." That's what they told me when I called. So, the Range officer is really nothing more than the MILSPEC, with an adustable rear sight, beavertail grip, long trigger (but about 5+ lbs pull, not "match" ). It's a nice piece, but it is NOT a "specially fitted" 1911.
