JM, Did APW have to reblue after the porting? I have the stainless slide on my PT145 and for the money it is well spent. I live in Largo and APW isn't far away. They are just usually very busy. What was your turn around time? Thanks for the info.
I think Cogan had to reblue, but you can't tell by looking.
APW has since moved to Alabama, so not so close, at least to me, but they will take care of it by mail.
Email or call them and they will give the full details - great service - a a lot of info on their site linked in a previous post.
How much of a difference did you notice with the porting in recoil reduction and also blast/flash affects? I have had Mag-na-port do a few for me and have been pleased with their work. I might have Cogan do a P3-AT for me as well.
