Maybe if the springs are swapped for better ones. It seems these have a very short lifespan.
The ROA is the best, to me, because it is made of superior steel, has better parts, has better sights, has the bushing over the cylinder pin, and has a bit more power capacity.
However I don't care for the loading lever system that comes apart once removed.
If there was a Remington NMA model made of modern pistol steel with a bushing, stronger springs, and better sights I could be swayed even with the slight reduction in powder capacity.
I look at this through the lense of hunting where reliability, strength, accuracy, and power are rather important.
My NMA does well with 30 grns of 3F Olde E or T7, whereas my ROA does well with 35 grns and reduces the group by nearly an inch at 15 yds. The difference is a standard .45 ACP level of power compared to a warm .45 Colt level.
So I truly love each for different reasons. The Walker and Dragoon first got my attention for the look of it, but the Remington came home because it was more reliable and handy (5.5" model). But that was in part due to the ROA adjusting my view as I thought the NMA looked ridiculous at first. The Ruger softened that stance it seems...
