On my shopping list was a Smith and Wesson model 36 "Chief's Special" and I got a nice one, in 38-Special, with its original box. Probably 1960's vintage, so I had to do the 4473 thing.
The other gun was the ubiquitous Nagant. They're still under $150, people! And C&R eligible; they'll send it direct to your door by UPS Next Day Air. What's your excuse for not having one?
And look at that firing pin!
It loads like, well, what it is: a nineteenth century revolver. There is a loading gate on the right side. The ejector rod is swung into position and pushes out the spent casing. You can see the tip of the ejector rod peeking out of the cylinder, above.
The ammo is unique. The mouth of the case protrudes beyond the cylinder. When the gun is cocked, the cylinder is moved forward a couple of millimeters to form a gas seal with the barrel.
So to facilitate maximum plinkage, a replacement cylinder is available to convert it to 32-ACP. Here's a video of a guy trying one out. He did not seem too impressed.
With an effective gas seal, this is one revolver that might be suppressed effectively, and it has been done:
I was disappointed that there seemed to be no S&W M&P 9mm compact magazines at the show. Also on my shopping list were a pair of Peltor earmuffs to protect my aging hearing. Maybe later. As for the mags, I'm on the waiting list at Cheaper Than Dirt. Hey, it worked for the Ruger 22/45!
