I second everything Quentin2 said regarding the Ruger vs Remington and different models. Basically. If you want a GI type pistol, go for the Remington, if you want some extras like the beaver tail and a longer trigger without such a plain GI look, then go for the Ruger.
I also did what Quentin2 did and bought one of each when they were on sale for $75 off with an additional $75 rebate. However I didn't buy a commander! I wish I had!!! I saw one in stock, handled it, liked it, but didn't have the money for a 3rd, lol.
I've shot both the Ruger and Remington. I like both. For me the only deciding factor would be which style you are looking for or prefer... or possibly price. Which was why I got the two R1's
Another thing. I experienced slide bite from both of my Remingtons, so I filed down the hammers one notch or so and smoothed them out. That took care of it. I also prefer long triggers vs the short ones they come with. So I've ordered a couple long replacement triggers and will be installing them sometime in the near future.
