The moderators aren't doing it. It appears instead that the original thread starters have chosen to delete their posts. If they wish to do so they have that right, but when found we're simply deleting the threads rather than continue discussion on a topic for which the original post no longer exists.
Avoid the temptation to replace everything on your brand-new 1911 just to make it "better". Know what you're changing out and why. You may spend a lot of money fixing things that weren't broken to begin with. Shoot at least 500 rounds through it first, then decide what you don't like and want to improve. Regarding vintage 1911s, pre-1946 pistols are highly collectible in original, unaltered condition and should NEVER be refinished or modified as it completely ruins their monetary value.
