Haven't shot the Commander lately but I had one a few years ago and it worked very good. I have the Defender now and it runs flawlessly. It also had sharp edges on the bottom of the slide and a couple of other places but it was stainless and alloy so I just took a stone and ran it along the edges. It has worked well for me.
I wish I knew what I doing wrong I almost 6'3" and 300lbs My PPK/S won't bite me and never had a Colt cut me I got to be doing somthing wrong :-D
All my Combat Commanders are more accurate than me. I have never had a problem with a Colt . Others yes but not Colt that why I have all Colts in a 1911 type pistol.
