I have had several different 10's over the years, the only one I would be weary of is the Colt Delta. They are great guns, well made, except some of them have very poor cartridge support in the bbl. Maybe Colt has fixed this now, but I doubt it. Yes I know friends that have those guns that were fine. I have helped friends buy used Deltas that had great support. However, some of them are down right dangerous and can only handle powder puff loads. I have corresponded with quite a few that have this problem. If you buy one, take a dummy cartridge with you and put it in the barrel and look at it first, compare to another barrel that is good in that department if you don't know what your looking for. I can't understand how a company like Colt can let something like this slide. (no pun). It is BS, and with the one I had they said it was in specs. Mine made bulges in the case with any normal or slightly hot load. We are talking bulges not just smileys. Checking barrel support on any new 10 (not talking revolvers) is a good idea. A ramped barrel seems like a good idea for the 1911 type guns, although I am no expert. And remember if you buy a 1911 style gun, swapping a bbl out for an aftermarket is not quite as easy as with a glock, and you may cause yourself some headache if you try to do it yourself and botch it.
I like the concept of that Redhawk, it probably feels like shooting a .38 special, and would be a fun gun. Agreed if you were to hunt with it, why bother, go to a bigger cartridge. .
