Good on you, Evangelist Cowboy.
That boy will remember you and he will do the same someday.
My grandson also prefers revolvers over semiautomatics in handguns, but he sure loves his 10/22.
A couple of years ago I was shooting a couple of my cowboy guns at an indoor range and there was a boy there that was fascinated by my stainless Ruger Vaquero (original model) .45 Colt with a 7.5” barrel. I let him shoot it. He really liked how big the gun was. I think I made a convert.
His family were all shooting semi-autos.
