I had Magnaport do a conversion on my 629. I intentionally deleted the porting that was included in the package for a couple of reasons.

First, I had read in ALOT of articles that said that the benefit of porting was "insignificant".

Also, after having a gun ported you decrease your buyers for that gun as most people don't want/or wont pay for a ported gun.......thereby decreasing the market for your gun and it's value.

I will never get the money I have invested in my 629 back even without having it ported but it did'nt matter to me. I wanted an heirloom gun and thats what I got.

Magnaport does beautiful work beyond porting.........
