I have two new 1911s: a Colt Series 80 (chambered for .38 Super) and a Remington R1 (for .45 ACP).
The Colt instruction manual says, "Extensive use of +P ammunition will accelerate wear in your pistol
The Remington website www.1911R1.com
says, "The 1911 R1 is designed for use with industry standard SAAMI spec ammunition. It is not designed for use with +P ammo nor is it recommended that this ammo be used in your firearm
I seem to recall reading that any recently manufactured 1911 should be good with +P. I'm not too concerned with the Colt warning, but I'm a bit surprised at Remington's prohibition. Thoughts? I wonder what other current 1911 manufacturers say about the use of +P?
