I predict Ruger will own this market with a medium-frame polymer/alloy/steel wheel gun - I call it the LSR for Light Service Revolver. What excites me about the concept is the potential cost savings over steel revolvers and the much improved potential for carry.
I'm thinking about something the size of a hammerless K-frame, barrels of 2, 3, and 4", and a weight of somewhere between 22-oz and 28-oz, depending on caliber and barrel. I'll take a 5-shot .44 Special, a 6 or 7 shot .38/.357, and a 10-shot .22 LR, for starters. Street prices under $500. Who's with me?
