I have a Springfield Range Officer 1911...for about 9 months now. Overall a very attractive pistol with all the things you might initially want on a 1911. Liked not having the front serrations (more of an original look and not so copy cat). Have been runing off the shelf ammo and reloads. Feeds everything except some very light load SWC plated bullets I made up and only a couple of fail to eject out of some 100 rounds...everything else was flawless. No problem with the provided magazines, but also running a couple of Wilson Combat ETM mags (and not running the SWC through the stock mags yet...don't know if there is a difference...just didn't want to push any luck there).
Have noticed from research that the ROs were shipping with sights low and left. Mine showed up the same and a bore laser verified the issue (thought I really sucked at .45 shooting initially). After adjusting the rear sight (there is a set screw under the elevation....side adjustment was not enough to correct...and they are glued down with some clear stuff like loctite). Also there was an issue with the rear sight cross pin sliding out...mine had that also even though the holes are staked. Super glue for a quick fix.
Although the rear target sight was looked at as a bonus (main use for target shooting), it is bulky and sharp.
Overall, the fit, finish and function has been excellent and the gun is overall a very good buy.
