Jon, I dont have an Alaskan, but I have had other largish revolvers through the years; ie, 7 1/2" S-BH and RH, 6" 629, 3"ish 629 Lew Horton(?) and ALL were too big for a true 'belt gun' IMHO. That is to say, one on the left would give me a serious 'list to port' and/or be trying to pull my pants down and be getting bumped in my day to day activities and chores. Same was true with strong-side or crossdraw, with the crossdraw getting in the way and bumped way more than nice grips ever should.
My solution is a shoulder rig (somewhat of a basic 'western style') for the shorter barreled revolvers like the 4 5/8s or less, but it should be OK for 5-5 1/2ish, I think. There is an over the shoulder rig to take a regular hip holster that looked promising, especially for longer barreled or scoped guns.
For me, the gun is out of the way in daily activities and just carries better in the shoulder rig much more than the hip type, and it gets out of the weather too when I cover myself.
