Original Barrel Throat

So, I was at the range the other day with my Colt O1918 when it dawned on me that I have been shooting hollow points, semi-wadcutters, and even really short button nose bullets out of my pistol with all feeding exceptionally smoothly (no malfunctions or "ker-chunk" feeling during cycling). I have been using the stock magazines exclusively to boot. So, what caused the original barrel throat dimensions to get a bad rap? Am I just lucky?

Colt started putting a little dimple on the barrel ramp about eleven years ago. This was discussed here about a month ago in the Colt subforum.

The O1918 Replica doesn't use the dimpled feed ramp. It uses a similar, albeit slightly larger version of the narrow GI-style ramp. To be honest, ever since most JHP ammo began using a rounded bullet ogive malfunctions have been reduced, even in old mil-spec pistols with the narrow ramp. SWC and truncated cone ammo will probably still give problems, however.
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.
