where can i buy a Ruger birds head in .45 ? i now have the cash but can't find the gun!!

Did you try www.gunbroker.com? How about www.gunsamerica.com? They would be where I would start. Otherwise, have you tried to order one through your local gun shop?

There is one on Gunbroker that I found. Its aution # 52385338. It currently has over 19 hours left and is at $430. Its blued with case hardened frame.

$430 doesn't sound like a bad price. IMO.

I also found one on Gunsamerica. I cant remember the exact ammount wanted, but it was around $550. There was also a stainless pair in consecutive numbers there for around $1200. They were two of 500 made in that particular setup.
