Greetings, HJshoots
Here are my favorite air pistols:

Crossman Vigilante (BB/pellet) $56

Umarex Walther PPK/S (BB) $78

Sig Sauer 1911 "We The People" (BB) $100

Smith & Wesson M&P (BB/pellet) $43

The last one in my case is an Umarex Morph-3X (BB). Sadly, it appears to be unavailable at this time. I've used this to shoot mice at 8-10 yards with the long barrel. Pretty accurate for a BB gun, but no match against my Avanti Champion 499B.

Two things:
I over estimated the distance I've shot mice with the Morph. It's closer to 3-5 yards.
Also, the picture attachment looks like it didn't upload. So, here it is again:

Damn... forgot one!
This one isn't in my case because I carry it in my western holster:

John Wayne Colt Peacemaker (BB/pellet) $150
