Perfect hog pistol.....

Puma model 92 lever action in .357. No it's not a pistol but it's easy to handle, carry, and shoot. Hard to beat for less than $500 NIB. I've seen hogs dispatched with em while running through a field almost 100 yards away. I've seen the same rifle poked down into a brush pile and held to a hogs head before squeezing the trigger. That sucker was burrowed in like a beaver in it's dam!
Those little lever actions in the .357 mag are just plain handy. Get a sling for it and they are less cumbersome to carry than a big bore pistol in my opinion.

For a postal I will only carry my Super Redhawk 44. I've planted hogs out to about 40 yards with it but have missed them at closer range. I don't even consider myself an average shot with it or any pistol for that matter though.
If you look long and hard, you may be able to find a good used one at that price or cheaper.
Good luck on your choice.
