About five (5) years ago, they customized a S&W Model 13-2 3 1/2 inch barrel for me. They ported the barrel, bobbed the hammer, converted action to DAO, slicked and rounded the trigger, etc.
Around that same period, they also ported a Model 66 2 1/2 inch and several J-frames and Pro-Ported my Scattergun Technologies Remington 870. It took about two and a half weeks from outgoing to return on each order.
I have been VERY pleased with the results!
