I have shot both revolvers the 500 454 and 460 I get to go once a year and play the the gun producers new toysThese guns generate alot of felt recoil,but are controllable.I just wouldn't want to shoot hem a whole lot

Remington still markets some calibers as peters

Sorry its actually a pre 15 Smith and Wesson did not assign model numbers till 1957

I have model 15 made in 1952 one of the most accurate revolvers I've ever shot.It has 4 inch barrel and adjustable sights
