I get a chuckle every time I see these threads... The responses are always the same - "If you want to blow the head off of an elephant at 1,000yrds, then you need a large frame old Vaq, if you only want to shoot sweet pea cowboy loads that won't even lift the muzzle, then the New Vaq is ok"...
Because there's obviously no middle ground between those two things...
The New Vaquero, while not as strong as the original Vaquero, is still capable of Tier 2 "Ruger Only" loads, which are still plenty stout. Not to mention they're capable of handling any SAAMI level factory. I'd venture that 90% of fellas that had original Vaqs never even shot a single round that was over standard SAAMI factory spec, but now that the Vaq's have been shrank, it's suddenly it's a high priority to have that capability.
Big bears have been dropped in their tracks by a LOT lower power rounds than a Tier 2 45colt.
Most of the arguments for 45colt "Big Vaq" as a bear defense sidearm or as a large game hunting revolver is moot anyway: The reality for most folks is that if they need a hunting revolver, they're not carrying a fixed sight model. If they need a defensive revolver, they're not carrying a single action. If they need a lot of power, they're not carrying a 45colt.
I like .44mags, so I like original Vaq's for that cartridge - new vaq's aren't big enough to handle the pressure of 44mags. In 357mag or 45colt, I like the fact that the New Vaq cylinders align in the loading recess without spending an extra $125 for a Power Custom Half Cock hammer.
My current project(s) on my bench for myself is a pair of 44mag Big Vaq's, my next project on the docket is a 45colt New Vaq. Take your pick.
