I bought a Colt Series 70 Combat Commander in brushed nickel brand new about 1979....and with it a Government model series 70 in brushed nickel.
bought them both at the same time.
I was just learning about 1911's back then, and these pistols taught me a lot.
They both ran well, the all steel commander I had taken to the tool room where I woeked and had a good polish job done by a fellow shooter, and it fed ammo without a hitch. I was hard on both these colts, kept them clean and lubed, but was pretty hard on them, and they never let me down. I kept them stock, I don't get "hammer bite"...never had that problem with stock grip safeties, the only thing I changed were springs, and I also got rid of the bushings eventually and got some solid ones without those fingers on them. These are good 1911's that you can do what you want with, and if you do have a problem, it can be fixed.
Now about that brushed nickel finish....I'm telling you after I used them, carried them, handled them, bumbed them, scuffed them up, these brushed nickel pistols looked like crap. LOL!!!!!
I never saw anything so ugly after they got full of dings and nicks and scratches...and when you scratch brushed nickel, guess what, it's shiny in those spots. The brushed nickel looked great in the store, but I use my 1911's a lot, and I'm hard on them.
Other than me not really liking brushed nickel myself, the guns were great, and still are.
I can get them refinished if I want someday, I kind of gave them a good cleaning and put them away a long time ago, I'll decide what to do with them someday. right now I'm wearing off the finish on a SA Mil-Spec.
I love 1911 pistols, and Colts are military spec and are great pistols.
Your going to like your all steel Commander, and you can fix any qurks it has, if any, without dumping too much money into it.
Or, if you want to add bells and whistles, the all steel Commander is a perfect pistol to do this with.
Great purchase you made there.
