Years ago I had Kelly and Mag-na-port do a 41 mag blackhawk for me, he also jeweled and polished the hammer and trigger.
It was an excellent job, and I could tell the difference in felt recoil.
Noise? HUH? The 41 mag is so loud anyways, who would know...
plus, I'm thinking the ports were so close to the end of the barrel, what difference would it make. The 41 mag is loud when you touch it off in the woods, wheather ported or not, I could not tell the difference myself.
I hear the name Ken Kelly being used in 44 Man's post....
Must have been a long time ago when I got my gun ported, I remember the name Larry Kelly...I think....Boy, I'm getting old!!!
