I do love the 357. I would never give up my Ruger GP-100 with a 4 in. barrel. Or, uh, I mean I wouldn’t have until that boating accident. No other handgun feels as comfortable, natural and solid in my hand. They are just too big to carry concealed but are an awesome sidearm. The only issue is, are 6 rounds enough? That’s a decision each individual has to make.
I suspect there is a correlation between magazine size and number of rounds expended, yes. Funny, that.
There’s numerous reports over the years of multiple officers emptying magazines dozens or even hundreds of rounds fired, and nobody hit anything. At least the “bad guy” anyways.
