I have a 2 1/2 inch Model 19 (Round Butt) with a non pinned barrel. I bought a used 4 inch Model 19 barrel to have installed. Besides a longer ejector rod what do I need to do to swap out the barrels? Besides proper head spaceing, how big a deal is it to replace the barrel and about how much should I pay a local gunsmith for the work.
Thanks for the help!
