The most important thing about a shotgun is fit. The gun must fit
you. If the gun fits, it doesn't hurt to shoot it, and you are a pigeon breaking machine.
I prefer an over/under, I shoot an Italian gun, my gunsmith, now departed, worked over the stock, It has little resale value, but it is the last gun I would sell.
Having said that, it makes more sense to spend a couple hundred bucks having the stock fit on a $1,500 stack tube rather than spending the same $200 fitting the stock on a $300 pump gun.
Thanks a lot for the feedback. You are right about the fit. The person who was instructing me said that a beretta would fit me better. I had a difficult time getting the Browning to fit nicely against my cheekbone. I was budgeting around $1000 for a gun.
