My revolver of choice is Pietta '58 Remington New Army .44 BP with R&D conversions to .45LC.
1. Of course, is PRICE. I am just a poor boy.
2. Looks, I just love the look of the gun and like those 8" barrels, they feel more comfortable in my hand. I am in the sport for the fun more so than the competition. I only compete with me, try to better my score each match.
3. And the authenticity of the model never gets questioned. Purely period correct.
