I believe you can get a .45 caliber handgun that fires .410 rounds - that would be very effective at close range against varmints without having to worry about aim very much.

You can also get shotshell rounds in .45. Might want to consider getting a spare clip, and carrying a clip of solid rounds and a clip of shotshells.

I believe you can get a .45 caliber handgun that fires .410 rounds ...30-40yd range (the max range Ill likely be shooting pop up varmints at)...At that range, the .410 wouldn't do much more than sting their hides...

You might consider a Contender with a 45 Long Colt/.410 barrel. Don't forget there are .410 slugs as well as the 45 for the longer shot.

Even with a 10" barrel you might not like the size/weight, but the durability will be there.

Yep, It's an O/U derringer style pistol, chambered for the old 45 long colt rimmed cartridge. This chambering will accept .410 shotgun shells.

I've seen them advertized in the Shotgun News. One version comes wih a 6" or maybe 8" barrel, and would probably be usable out to 20 yards or so.
