I originally tried to carry a P10C with a micro comp, but recently removed the comp. I found for the added dimensions there was very little improvement in recoil control. It not only makes the gun more awkward to conceal, but also makes it harder to find a holster that will fit. I think comps have a place for target shooting but I'm not so sure for a carry gun. Thoughts?
Also, I do still have a comp on my Glock 20 10MM. It's more for outdoors and bear country, so I have more options to carry it comfortably. It's a large 3 port comp and it does seem to lighten the recoil enough to justify having it on.
