I am looking for information from anyone that might have experience with extended ported barrels installed in the kahr k9 or springfield xd pistols in 9mm, 40 or 357sig. Do these extended barrels reduce recoil about the same amount as the factory ported barrels? I had the chance to shoot rental guns (G19C and G23C) at an indoor range and liked the way they reduced the recoil and improved the shot times. I have read on the forum that factory ports darken the front sight after a while so I was considering trying the extended barrels.
I know from reading posts about ported barrels that there are different thoughts about ported guns, but the ported glocks had way less muzzle flash and recoil than the .357 SP101 that I have been shooting.
Thanks for your thoughts,
