Here's mine, just a small sample, all handguns:
From the top, down the left side and back up to the right:
My 1911 Springfield Loaded .45. A favorite for obvious reasons.
Under that, a Rossi .44 Spl. Sweet gun, but it doesn't shoot that well beyond 25 yards.
Under that, Ruger P89. Nuff said.
Top right, one of my very first, if not the first handgun purchases. S&W 586 in the six inch barrel. .357. I love the handgrips on that gun, very solid and they fit my hands just right. A classic I would never sell.
Under that an S&W Military and Police .38. A gun that came out of the California prison system. I picked it up for what, $150? A freaking steal in today's world. No signs of holster wear on the barrel or the cylinders. I doubt it had fired but a few times. Locks up true and tight every time. A real keeper.
And then, everyone has to have a "garbage gun" or two. This little Rossi .38 is one of mine. I don't know, I just like it.
So, what's yours?
