3. A useful comparison is the 1911 in .40. The .40 can be thought of as a type of .45 +P, since the bullet's only 50 grains different. There's a reason that Colt, Kimber et al dropped it not long after the introduction. It's too much mass and too much pressure for the 1911. Slide goes too fast and it can cause intractable problems. The design just won't handle it.
So the 1911 can handle 9mm +P and .38 super, but not (reliably) .40. I'd say the .45 +P is more like the .40 than it is the smaller calibers.
Again, I'd pass on .45 +P. You're asking Browning's gun to do something it wasn't designed to do.

That's some of the craziest stuff I've heard in a while. The 45 ACP will push a 180 grain bullet to around 950 to 1000 FPS. A 40 S&W will push a 180 grain bullet to about 950 to 1000 FPS. Boutique ammo will push bullets faster for both rounds.
I have 6 1911s. The Colt Delta Elite is the lightweight of the bunch. I just weighed all of them and the DE weighs in at 2 lbs 3 ounces. All the others weigh more - from 2 lbs 4 ounces up to 2 lbs 7 ounces. Where is the slide and frame beefier on the 10MM? I'm not seeing it.
The Delta Elite does have a double recoil spring but that's more for marketing than anything else. The recoil springs main job is to load the next round from the magazine. The mainspring and firing pin stop have a much more pronounced effect on retarding the speed of the slide.
Sure +P will increase wear slightly, but you'll have spent many $1,000's on ammo before you'd ever see any difference in wear.
