I have had an R1 for 9 months and I love it.
Just a bit of info. Contrary to what the "internet" says, the Remington 1911 are 100% American made in NY. This has been stated by Remington on several occasions, but the rumor persists. It is tight and very accurate. It has a match grade stainless barrel. There have been some complaints about the trigger having a bit of creep, some not all. Mine had it. Remington fixed it free and fast. It was gritty and quite dirty from the factory. Cleaned and lubed it properly and it is smooth as glass. Slide and rails still look like brand new. Not much visible wear yet and mine has over 5K rounds. It is a tack driver shooter. I shot an 8 round clip into a standard silhouette at 75 yards. All were lethal, head, neck, and mostly center mass. Everybody who has shot it really likes it. All the workers at the range I go to come in an shoot a clip or two anytime I have it there. I also shoot my loads a little hot because I like the full experience when shooting. I usually load 200gr to about 1050-1100 ft/sec. Gun shoots them just fine and by the 1000's. It's still as tight as the day it came from the plant.
It really bothers me when people just continually claim knowledge about something that they heard from the cousin of a guy in Korea who told him his uncle in Australia told him how this gun sucks or is made of z-metal, etc.... In fact for the money, it's a damn good shooter, and well made. Are they all perfect? Of course not, but easily the majority are good guns.
Here's the very first clip fired from my R1 5". The low shot was first since most of my guns shoot 6 o'clock picture. Rest kinda went where they belong. This was 10 yards standing free hand:
And this was a shot after i put a set of Rosewood grips on it
Like quack says. Your pick. Pick what fits your taste, your shooting style, and most of all, your budget.
