I just ordered a drop-in kit from Clark Custom, should arrive before the weekend. This is going in a Kimber Classic Royal (series I). Does anyone have any suggestions to offer before I install and use the kit? Yes, I know, it's almost a wildcat ctg and hard to find rounds (I have a tonne of ammo to feed my Dan Wesson .460Rowland revolver, and my son reloads). And I expect it to be a handful (I like recoil, for reasons I can't articulate - love my .44Mag and .41Mag, as well as the .480Ruger, .454Casull and .460S&W Mag). I don't expect it'll get as much range time as the .45acp, but I have 4 1911s & 4 revolvers in .45acp (and 1911s in 9mm and .22LR) so wanted something different.
