I got a Blackhawk and a GP-100 in .357 mag. Both of these revolvers handle max loaded ammo with ease, everyone knows Ruger builds a durable piece. I don't know if a 13 year old would enjoy a magnum handguns recoil and noise or the legality of a minor with a handgun. Barrel length is always something an individual should determine, I personally like the 4-4 1/2 inch revolvers barrel length for ease of carry. For sure it cost range and power but I only shoot handguns at archery distances.
I have seen plenty of kids with pistol caliber rifles. One would be easier to shoot accurately and with added velocity over a wheel gun.
