Overall I prefer my carry guns not be compensated and I have shot my M44C at night as well as some compensated glocks (10mm's as well as others) and find that I shoot just as well with standard vs compensated guns even when rapid firing. I'm not going to win any competitions by any means but for close up work I don't feel they are completely necessary. That being said, I am carrying my M44.. which is why I am checking I'll carry either.
This is a Good Read to the end...<) about half way down the page it gets into Porting... It seems to say Yes to porting...
Some Magnums Jack-Badly, and porting could make for a Quick effective Double-Tap...<)
My .45 1911 has a extra 1" long barrel, and is Ported, and it keeps the Barrel down, and less recoil, making it vary easy (fast) to retarget the Laser for each consecutive shot... I have never shot a +P in my .45...
I wouldn't have porting on a gun primarily for carry as I don't want the possible drawbacks and don't need it to handle the recoil (grips I will change). The only time I might have a ported gun for carry would be if I was using a ported 44 mag (which I don't currently own) as a carry gun but I highly doubt it would be anywhere near the top of the carry rotation list unless I move much farther north or west. ;D
While pieces of powder, etc. can splatter out of ported handguns I like them and wouldn't hesitate in most cases to carry one for personal protection. Low light muzzle flash might change my mind but in a SD situation I wouldn't care if it didn't impact my vision.
The biggest problem I have is the extra cleaning they require.
I wouldn't and only because of the smaller calibs. I carry for CCW. But as I say this I do keep my Tracker 4" beside my bed. I figure even if I miss and they get me the muzzle flash will make at least clean their britches.
