I recently bought one in .41 mag in excellent condition with Hunter cowboy holster for $300.00. I snatched it up right away as it's my favorite caliber and the price will only go up on these of "not normal" caliber like yours.
I'll shoot it, use it but not abuse it as I'm more an accumalator than collecter and hardly ever sell.
I've found the odd ones are usually worth more later but buyers are fewer also. I've picked up several nice .41 mags at good prices for that very reason.
