Probably over paid, but I ended up getting a little Beretta 950 in .22 Short off auction. This is one of the "sort of" hard to find models with the extended barrel that's said to be particularly useful for putting a suppressor on.
With 2 spare mags and 1000rds of ammo, it came out to 275 plus shipping/FFL fees. Eh. I figured that was about 100 bucks or so worth or ammo and that the mags were worth about 20 bucks per, making it a roughly 135 for the gun itself.
If I end up staying in VA, I'll put a can on it eventually.
