what is the difference between ported barrel and comp'd barrel???

I've seen ported (Or is it comp'ed) bushings you can put on a 1911. Have no idea if they actually do anything, though.

Those are the compensators being discussed above. The biggest thing they add is weight to the slide. As the bore has to be large enough for the barrel to pass through as the slide moves, the gas sealing is not as effective, so less gas is redirected by the ports than say one that is fitted to the barrel and bored just over bullet diameter.

Those are almost useless on a 1911 using standard ammo. It may work better if you used an ultralight bullet (160 grain) and +P+ pressures.

I had a similar one on my Springfield 1911, and I didn't notice anything with standard ammo.

I tried a different one on my Springer. Noticed no change in recoil, and a loss of accuracy as it was not fitted to the barrel. Gave up that experiment pretty fast.
