last but not least (I promise, for now..) I'd like to submit my (Granbury, Tx) Bond Arms Snake Slayer – a 2 shot Derringer type of set-up – with this pistol if ya wanna shoot different calibers ya just buy additional barrels – I happen to have one barrel that's calibered in .410 shotgun/.45 long Colt and my other barrel is .357mag/,38spec (and shooting .357mag isn't a wrist killer)
change barrels simply using an Allen wrench and remove 1 Allen screw – replace barrel, return screw
rotate the barrel to load or remove spent cartridges, lower and it “clicks” to lock closed – you've gotta pull the hammer back in order for the pistol to fire (shoots the top barrel 1st, re-cock and it'll shoot the bottom barrel)
it weighs 22 or 26 ounces depending on which barrel I have mounted and Bond offers barrels from 2.5” to 6”, in calibers .357mag/.38 spec, .45long Colt, .45acp, .45LC/410shotgun and 9mm
they offer grips made of different materials and 2 different grip sizes/length
this is a nifty little pistol and the workmanship by Bond Arms is top shelf– very light weight for carrying around the property – not a bad purse gun for the Gals too
