I like the looks of the 45 colt/.45 ACP Redhawk.
As one who had an early Redhawk .44 Magnum in my younger days
(21-24) I also have a bad back from carrying heavy .357s , .44 Specials,
.44 mags, not to mention 20 years of carrying a heavy Sam Browne belt
The trigger pull (at least in DA) is a bit hard for me to bribg back the hammer.
A LCR or SP-101, and even a GP-100 is better for me.
My thinking is that if Ruger, can bring us the wonderful .44 Special in a
GP-100 format, why not a .45 ACP revolver?
My wife likes Glocks and S&W J-frames.
I've only had a few Smiths around the house and I remain less than impresssed
with any Smith with a lock.
A total seizure of my duty 66's cylinder moved me to Rugers, and I'm happy to say that
more than 25 years later, I still squander my meager funds on Rugers.
A GP-100 in .45 ACP would probably be a bit heavy for my back, but nice to
shoot at the range and for home defense as well.
As I no longer, .44 special no a no-go for me. Any factory ammo is either hard to come
by (especially practice ammo) or expensive. I can say the same for .357 SIG that I no longer shoot these days.
.45 ACP ammo is both abundant and about the price of .38/.38+P for practice.
The biggest Plus for a GP45 would be that it would be yet another Ruger revolver for
Terry to have to buy.
