If SS is what you want ~ I'd go with the Colt.
I have over the last 30 years only owned Colt 1911s. Sort of summed up what a 1911 is to me. Sold my last one a couple of years ago.
Something about a 1911 always calls you back. I recently bought a Remington 1911 R1. Wow!!! Is all I can say. This gun has been flawless as far as shooting out of the box. Accuracy is tops for a basic 1911 with a few essential upgrades.
Better than any of my previous Colts in stock configuration. In fairness, it does comes with a SS bushing, match barrel, beveled magazine well, lowered ejection port, and three dot sight system as standard features. Something that was after market on my older Colts.
I bought mine off of Gun Broker for $539. From what I have seen, mid $550s to the low $600s seems to be a going price. It definitely will not break the bank.
I talked some of the factory reps and was told that the frames and slides are made in Ilion, NY, with some of the smaller parts sub-contracted. The guns are built at the NY facility.
The only negative I have found was with the front sight. After about 300 rounds the front sight was getting loose. Close inspection revealed the set screw was stripped out. The front sight on the R1 is dove-tailed in with a set screw to secure it (Novak Sight). I called Remington and had a new sight and screw within a week. I replaced the damaged sight and as I applied pressure on the new set screw, I felt it stripping out??? I removed it and applied red Locktite to dove-tail and the threads on the new screw. After centering the sight, I was able to tighten it down and expect no further problems.
This is one top shelf 1911 at a very affordable price.
