First off I have to say wow some really awesome in for here and I thank all of you. I am a big .45 acp guy ( I own 4 of them ) and the idea that one gun could thoot three different rounds thrilled me. I love my 44......but its a big cumbersome colt anaconda with a 6 in barrel and not very good for backpacking.....and with some of the bears around here I want to make sure I have enough protection if I need it. That's why I liked the Alaskan....big power in a small package....and the idea that I could plink with 45 acp....and pack 45 lc or 454 for really opening up that industrial can of whoop ass if I need to. I am apprehensive about buying a gun chambered in a caliber I've never shot before and was looking for some assurance and I think I found it. Does anyone if the Alaskan will accept 45 acp with the moon clips or is that a myth?
