Considering trail carry REVOLVERS only up to .44 mag.; 329PD, 329 Night Guard (.44 mags) and 296, 396 Mountain Lite, 396 Night Guard and old Charter Arms Bulldog (.44 special). There is a 12 ounce swing in weights before adding grips, CA in the middle. Enough to notice in a belt pocket.
All but CA (all steel) are aluminum alloy frames, 329 and both Night Guards have part scandium. (The NGs have steel cylinders, the rest titanium. The magnums have cylinder notches on the chambers, the 5 shot specials' notch straddles the chambers. I understand cylinder strength is usually the limiting factor for hot loads, that question is for another day.)
I understand SW position is never reload and their guns will handle SAAMI pressures. If I want max SAAMI magnum pressure, the list is short,329PD or 329NG. But if I want to go lighter, the 18oz 296 or 396 ML are attractive. My thought is a hot loaded .44 special shot little, practice with SAAMI loads.
So my question is whether the .44 special scandium frame offers any advantage over the other specials as far as the frame strength for hotter loads? Maybe the scandium is just good for frame longevity? The 1" longer barrel of the ML helps of course. Please no CA bashing please unless you have first hand experience. Thanks for any rational thoughts.
