I am thinking about purchasing a Beretta 391 for my daughter. I found one for $750. The guy says has less than 500 rounds through it and comes with 7 chokes, truglo sight and geltek pad. The question I have is this gun isn't an optima. Does the optima barrel make that big of a difference? Also am I better to cut the stock down or look for a rl stock to replace the existing one with?
