Can't say I would opt for porting again but the "P" gun I shoot (and have for about twenty years)has Pro Pigeon porting in the bottom barrel. (Came that way from first owner) It does reduce muzzel jump but it also creates some hostile remarks from shooter on the adjoining posts. "noisey". I like it even if they don't. It's your gun..did you buy it to shoot or worry about resale. Some of these gun traders lose more trading then they will ever admit and it's not from a minor loss over porting.
Porting is a total waste of money....results are virtually negligible in addressing muzzle jump and recoil. The holes are messy, loud, and seriously hurt resale. Some have experienced splits in barrels in/around the ports. All that said...this is America so you can do what you want. Best Regards, Ed
I recently bought a nice Kolar combo with Wilkinson tuned bbls and porting already done. It didn't turn me off to the deal. Yes Id rather have had unmolested bbls, but with this buyers market I felt the price was right. I don't feel the gun is overly loud or that it impedes squad mates shooting.The porting looks like cylinder head chambers rather than a bunch of holes.Agree that cleaning takes more care.Not a horse trader so not to concerned about resale.Just my two cents.
I hate shooting next to someone with ported barrels. I've caught powder and lead pieces in the arms and face shooting next to some ported bbl guns. It does seem that some do and some don't. I notice that mostly the cheaper factory porting throws more junk out and back. If you reallywant it get it. Resale would never sway my decision. Just respect other on the line.
