Here's the guy who I trust. He seemed to like it and the build quality is serious, it is a tank from what I can tell. He is great about answering emails very quickly, like within 24 hours or less from my experience, so send him a message if you have any questions. Oh, and the pictures will clearly demonstrate that you can expect STOUT recoil with full power loads. He says that it's a blast to shoot with .45 Colts though.
If you plan on carrying .45 Colts on the street, look into Double Tap ammo. First of all, their prices are always lower than the competition. Their standard handgun calibers are usually 50% lower (Or better) than the competition and at the same time push Gold Dot and Golden Saber bullets at higher velocities. Their loads in every caliber are generally the highest power loads available and they use the highest quality bullets, cases (Starline I believe, nickel coated), primers and powders. Handloaders usually can't match their performance without overpressurizing, which goes to show you how carefully they select powders. Double Tap makes a significantly more powerful version of the .45 Colt (They say it's "+P") for use in strong revolvers chambered in that caliber. This gun will count as a strong revolver of course, a very strong revolver. I would love to be able to use a 300gr controlled expansion JHP in a relatively compact handgun. It moves at 1325fps and 1170ft.lb. out of a 7" barrel (1688fps out of a 16.5" carbine!!), so I bet you will still get at least 1100fps out of the load with the Alaskan, which is serious for a freakin' 300gr bullet. That is going to be a heavy hitter to say the least.
Gunblast's awesome review (By Jeff!!):
Double Tap .45 Colt +P:
Double Tap .454 Casull:
Of course, their .454 loads are downright INSANE. One puts out a 400gr (JEEEBUS!) WFNGC at 1400fps and 1741ft.lb. out of a 7.5" barrel (1675fps out of a 20" carbine!!). The same 300gr Controlled Expansion JHP that was in the .45 Colt round is pushed to 1650fps and 1814ft.lb. out of a 7.5" barrel when loaded to .454 specs (And a blistering 2085fps out of a 20" carbine). I am liking this cartridge more and more man. I might have to get a carbine in this caliber, it's going to nail somebody pretty much as hard as a 12 gauge slug will. With a good expanding bullet it may hit harder due to the quick acceleration that takes place once it hits flesh and expands.
