I'm sorry, I can't comment on the two brands you're asking about. I have done some reading on the Remington and am considering purchasing one. Another one in your price range that I have shot many times via gun range rental, is a basic model Para-ordinance 1911, this is probably what I'll wind up with. The Rock Islands look good for the price, they may not be still manufacturing, but there are still plenty to purchase
Of course, if you just want a single action .45acp that is dead reliable and very accurate the sig 220 is hard to beat.
Here are your production 1911 rankings, from someone, moi, who probably has sold, handled and shot over 5,000 1911s factory, custom and whatever:
1. Colt SCG or any Colt from their custom shop
2. Wilson Combat
3. Les Baer
4. Colt Rail Gun
5. Colt Gold Cup
6. Colt XSE or standard 1911 if you want the retro style
7. Springfield TRP.
After that comes the SIG series guns, which arent true 1911s. Then follow the S&ws and the rest of the Springer line. Kimbers dont make the grade. Plastic guns dont deserve to be mentioned.
If you really want an auto, but dont need a .45, get the new SIG 210. Wayne Novaks shop and Bill Laughrides shop build excellent 1911s, on par with Bill Wilsons and the best colts, but they are "custom"
M&P .45. Read this review from the renowned 1911 pistolsmith, Hilton Yam.
If you want American made, it's either Kimber or Colt. I bought a Custom II in your range and am happy with it. If you want the best bang for your buck I recommend looking into Springfield Armory's line up. Especially once you get into the 'Loaded' Variant you get more for your money, the price being that it isn't made in the U.S.A.
I wonder what the profit margin is for those 4 digit $ firearms...Here are your production 1911 rankings, from someone, moi, who probably has sold, handled and shot over 5,000 1911s factory, custom and whatever:
1. Colt SCG or any Colt from their custom shop $1,850
2. Wilson Combat $2,250+
3. Les Baer $1,690+
4. Colt Rail Gun $1,029
5. Colt Gold Cup $1,029
6. Colt XSE or standard 1911 if you want the retro style $800+
7. Springfield TRP. $1,674
I would be willing to bet that 8 out of 10 civilians would shoot no better groups with the $1800+ custom shop Colt as they would with the Springfield GI model.
