The Mummy's Hand

Was surfing, and caught clips of this on SciFi last night. There's a scene where the female lead shoots a gun. It appears to be a standard revolver, but it shoots about 13 or 14 times. And she appears to shoot a heart in the door with it. Also, when she shoots at the door with it, you don't see anything indicating that the bullets hit it, but afterwards, you see perfect little holes that look like they were made by nails. After she shoots 14 times without reloading, she then threatens the (what I assume to be) the male lead with it. Duh! She *SHOULD* be out of bullets, but obviously it's one of those special guns... a "revolver of infinite bullets".
