I'm not a wheel gun guy... having said that let's start:
Ruger 22s: MK III Hunter SS and MK III 22/45 both with full VQ 'innards',
Now the fun starts... 1911s: Wilson Combats in 45 and 9mm,
Kimber Super Carry Pro and an Ultra Raptor both in 45,
And Compact platforms: Sig P238 Equinox in .380.
Any questions?
