At the risk of being tarred and feathered...
I just do not see the need for a new made N frame in 44 Special...
To me it is "waste of skin"... as a Klingon would say.
Why not make them all 44 Mag.
Oh for sure, shoot light 44 Special type loads most of the time, but then you have the option of going to the 44 Mag when/if you need it.
My Mountain Gun has the same slim barrel as a 44 Special, and handles just as good.
If I knew I would only ever need "44 Special" power then I would get a S&W in 45 ACP. I would then have the advantage of Full Moon Clips or the ability to use Auto Rim brass...
Don't even ask me about my thoughts on the 41 Mag. [And I did have and carry a Mod 58 as a work gun... If it had been a "M&P in 44 Mag I would still have it.
This is an old argument. The first time I remember hearing it I was fifteen or so ('64, '65?) and it was started by an article in one of the gun rags about Elmer Keith dropping the 44spl like a live grenade as soon as he got his hands on a 44mag.
The arguments for the mag ran pretty much like this:
1) The mag can do any thing the spl can do, plus a whole lot more on the top end.
2) The mag is just as accurate as the spl.
3) The weight difference between the two isn't that much, and with anything but the lightest loads, heavier is better.
4) They are both reloaders cartridges, so you might as well reload the most versatile case. That was certainly true in 1964, perhaps a little less so now.
The arguments for the Special ran:
1) Specials tend to be lighter guns and that counts if it is to be used anywhere but the square range.
2) Specials can be loaded up to the point that they will do almost anything the Magnum can do.
3) The 44 Special is inherently (magically?) accurate.
4) Special cases fired in Magnum chambers are inaccurate.
5) They are both reloaders cartridges, and most people will load their Magnums down to Special level.
I've messed with all these questions to some extent or another and FOR ME, it seems to sort out like this:
The Mountain guns and the special alloy guns make the weight issue a wash. In either caliber you can go as light or as heavy as you wish.
As far as accuracy goes, in a machine rest, the gun to gun variation is going to be greater than any difference made by the small difference in case length. In terms of people doing the shooting instead of machines, I do a lot better with a 250gr swc @ 900 fps than a 240gr jhp at 1300 fps. I just shoot better if I'm not being beat up, and it is as easy to down load a magnum as it is up load a special.
Special cases seem to work well in magnum chambers, from what I can tell. Again gun to gun variation seems greater than any problems caused by the shorter case.
If there is anything "magical" about the 44 spl, then it applies to the 44 mag as well. They are almost identical cases, generally shooting the same bullets, sometimes at different velocities.
If you wish to use a wide range of bullet types and weights, the 44 mag case gives you more options, at least on the heavy end.
All in all, I think Elmer was right when he dropped the 44 Special and never looked back.
One problem, though. I don't have any 44 mag revolvers. I've shot a lot of them, but none were mine. I don't want any 44 mags. I love my Specials because I think they are cool and that's what counts!
