Glad you guys like my idea.. I too think the Alaskan's barrel is too short. You can get the same velocities in a Redhawk .45 Colt 4", so why bother with a snubby? Now, a Super Redhawk in 454 would take advantage of the 1.5" increase in length. The SRH looks kind of weird with it's round barrel, but if you make it look like the GP100, adding a bit of weight for recoil management, then you'd have a winner!
I also wish Ruger made more blued guns, instead of all that stainless.. A blued Redhawk .45 would look great.
At this time, I don't think anyone manufactures a .45 Colt double action with a 4" barrel.. Really surprising since it would be the "perfect packing pistol." Given how many people are into CAS, and already own revolvers and rifles in that caliber, you would think they'd like a double action.. Taurus had one, discontinued it.. S&W only has the 6.5" model 25. Used 4" 25-5s are hard to find..
Enough already with the 410/45s.. The world needs a blued .45 Colt 4" double action! Not another weird looking shotshell oddity.
They don't have an email on their contact page, but maybe someone at Ruger will see this thread.
