I'd have to say my Judge. Not quite the club that Rack's Thunder 5 is, but it is a work horse. I also have .22 chamber inserts for it, which gives it a very nice range versatility. Can be used for anything from vermin to varmints to 2 legged predictors up to mid-sized game with a heavy .45 Colt load. That's a lot of range for one pistol.
1. Heckler-Koch USP-Compact. 3 calibers, 3 barrels, one frame, one slide, one recoil spring/guiderod, and one magazine.
2. Dan Wesson 1911 Bobtail Commander. 3 calibers, 3 barrels, one frame, 2 slides, 3 recoil assemblies, 3 magazines.
3. And yes I have a Glock 34. It shoot in Open, Limited, and Carry Optics divisions in competition with one frame and different slide, barrel and recoil assemblies.
Power wise it covers a large range. Down load it to 40S&W velocities and you have an adequate manstopper with manageable recoil and sufficiently flat trajectory. Mid level 10mm flattens you out further and offers some serious on-target energy, especially with a HP like GD or XTP. Go to the nuke loads and well...there's a reason the Danes issue them in polar bear country...
Size-wize it's obviously beefier than your standard 9mm, but not unconcealable by any means and if you're open carrying you're gold.
Haven't shot it past 40 yards, but I can reliably hit an 8" gong if I take my time. Up closer, follow up shots up to 10 yards are easy, up to 25 yards takes a second to recalibrate but is still reasonably quick.
Carry a moderate-power mag of GD or XTP for the cities and mag of hard cast nukes for country time. And at 10 rounds with a backup mag or two, I'm not feeling undergunned anytime soon.
Blackhawk 357.
From 148gr .38 WCs @700fps up to 200gr .357 LBTs @1300fps versatility. Absolute fun and flat shooting at the range that's also ready to roll any 4 legged critter on the eastern seaboard with heavy loads. 2 legged vermin can be easily dispatched with the 125 SJHPs @1400. Little critters or big, steel, paper, or people. Nothing it can't handle.
