Merry Christmas, to Me, A Contest For You

This morning I went to the last Tucson Gun Show of the year out at the Fairgrounds and I had some cash (emergency moolah for the trip) burning a hole in my pocket. I should have put it all back in the bank to plop into my IRA at year's end, but I peeled off some fifties just in case I encountered something I really wanted. If you can guess what I bought, you win a Blog Ad on my sidebar for a month. Leave your guesses in comments...you get only two guesses ever, so don't waste them all at once. Name the make, model, and caliber. If nobody's guessed it by Christmas, shame on you all!




Hints:

1. I paid $385 for a new firearm, tax included.
2. It's in a caliber I already own.
3. I have at least one firearm of this make, but not this model.
Update: 4. I went back to the show today to see if I could find one exactly like it. Chaos, you may have one more guess.

By the way, here's the URL for the gun anime source page.
