I was raised a Cowboy from birth in the late 40's. My Dad was a cowboy that worked many ranches in southern California and Arizona. I have his batwing chaps from the 40's that were made out of Elk hide and I shot in them for many years. About 25 years ago I came across a pair of shotgun chaps made of horse hide. They are light and good looking. Never had any problem moving with either pair while shooting. I was taught that Chinks were made and worn by farriers only.
Chaps were made to protect your legs while riding rough country. Chinks would only protect you upper leg, not where most of the brush will be hitting you while riding.

I have tuned many Yildiz shotguns and a few turned out acceptable, most were not. If you're content to go a little slower, the Yildiz will work for you. Like most Turkish made guns their design makes it impossible to set them up to break open easily.
The stoeger, when worked over by a qualified cowboy action gunsmith, can be a very good gun. There is just no telling how long it will last. I've seen some go well over 20 years, and some need help in 6 months

In my opinion you have chosen the best starting set of guns for a youngster. The Stoeger is one of the only S x S's that will shuck shells reliably.
