Abilene,
You saw my posts from awhile back where I wanted the option to fire the full 44 series in one handgun. You see, my second CAS rifle was a Marlin 44MAG and I still have it and brass. The Mag is not for full-house loads, just the ability to utilize all that brass. I could use the same load (8gr Unique and Lee 200 or 214gr bullet)in both guns. The same 'caliber issue' as in the olden days.
I agree with your 44SPCL loading comment, it is such a good casing. But I have never had a firearm that fired 44SPCL, so I want to now experience it.
It has now become the time to make a final decision as to what route to take. Since I could not get the lower priced Cabelas Pietta 44(again) this Tradtions is the only equivalent alternative. The other option is a Uberti Cattleman 4 3/4" in 44/40 (they are available from dealer around here, 44SPCL are not) and then add the 44SPCL cylinder but lose the 44Mag brass usage capability.
That is the real reason for this questioning. If someone stated the Pietta transfer bar has issues(unreliable, rough, sticks, bad timing) then its out. I go the Uberti route and forget the 44MAG.
