I'm curious about the differences between the browning buckmark (which I have) and the ruger mkIV (which I don't have). I like my buckmark camper a lot. But it cost half what the ruger does. I paid about $212 each out the door for a pair last year on black Friday. I got an email flier today advertising the MKIV at $458 on sale, before shipping and transfer fees... So what's the deal? Is the ruger a higher quality? Better materials? I know some prefer one over the other, but that's not what I'm asking; why such a price difference for similar pistols? Just curious.
