Compensator's Effect on Timing?

I've read and heard that the slide of a compensated handgun, (and gas opperated blow back systems), does Not begin its rearward retraction until the bullet leaves the barrel. Can anybody answer:

1. If this is true, how does the physics compare to a similar standard 1911?

2. What effect would this have on accuracy? I have some ideas, but would like to know of any first hand experiences with .45 ACP, Super, or .460 Rowland.

3. Does anyone know what the time between strings at one target are with a comp (describe which one) as opposed to a standard barrel? I'm deciding on a project which will allow me to carry 45 Super, or .460 Rowland and double for practice w/ACP. I have a 5"guvt slide, but considering buying a Commander length and adding an LSP 1.5" comp or short Ed Brown 1" comp. If YOU had the choice and could carry a guvt length, what would it be?

Wrong. 'Might' not move, but not cast in stone.

Pro shooters are 5-15% faster with comps.

Not required for carry IMHO.
Neither is 460 R.

A compensated, ramped barrel is much heavier than a standard barrel; that's why comped guns need lighter recoils springs - to allow the same cartridge to move a much heavier barrel. If the spring is too light, the feed reliability suffers - the "recoil" spring is as much a feed spring as anything. So, the heavier barrel is harder to get moving, and once it gets moving, it is harder to stop. Such guns would be more finicky about cartridge pressure, bullet weight, spring rate, etc., than a standard "1911" barrel.
 
What Rick B. says above applies to the addition of a comp with no offsetting reduction in slide/barrel mass. If you start with a Commander-length slide and barrel (3/4" shorter than guv't length), and add a 1" compensator, there should not be much difference in mass(weight) from a guv't length slide and barrel.

I have a compensated Colt Commander. It is the most accurate 1911 I have ever shot or seen shot (it has some other custom stuff besides the comp). The compensator is only 3/4" long and is the same dimensions as the slide so it fits in a standard 1911 guv't holster like a glove. The comp. has only six ports, but it noticably decreases muzzle flip and allows faster reacquisition of the target. I don't notice any decrease in the speed with which the slide cycles

Good luck with your project and finding bears to shoot with it :D. Hope this helps.

In general, the action is not slowed down enough to matter. Consider the guns used in the Steel Challenge.

Some of the guns have every whiz-bang gizmo known to mankind, including compensators, and they shoot pip-squeak ammo to minimize recoil.

They're going for raw speed, but having to hit targets (which are smaller than a man's chest) out at as much as 30? 35? yards.

You might be huntin' a solution when there ain't no problem...
