I just bought the 4" Model 10-10 .38 special revolver which was specially made (-10) for miltary and police. Im not sure But i believe the barrel thickness is much more Any one know? But i know the recoil is very small and the trigger is so smooth and light in SA and even in DA it feels light than most...

I have a 10-8, it's a great revolver. Love mine and carry it often.
