I added a 627 PC 5 inch gun recently. Man was I bummed with the factory DA pull of about twelve pounds. Also loaded moons (TK) would not drop in with 158 plated bullets. I installed a Wolf spring set that dropped the pull about two pounds. So I send the gun to Mike Carmony for tuning. The total time the gun is gone is eight days. Shipping time consumed six days. Yep Mike's turn around was less than 48 hours-!! Well now the gun has a 4.5 pound double action that is smooth as silk. Moon's can be thrown in the general direction of the cylinder and drop in. Service like this deserves a public thank you. Mike thanks a ton. I will send my 625 next. Bill Vaughan
