re: Pistola advice - Christmas gift

Actually, the 357 Magnum you already have will suit your current needs just fine. OTOH, I'd never discourage someone from getting another gun, especially if it gives his parents a chance to "show their love."

I'd take care of your current needs w/ a full size semi-auto; if you someday decide to conceal carry, get a smaller, lighter, single stack semi-auto at that time. I'd suggest your parents buy you a DAO or striker fired, full size M&P, XD/XDM, SR9, Sig or Glock. If you're comfortable w/ the SAO platform, a 1911 in 45 ACP is always a fine choice. Shoot and handle as many different of the aforementioned guns you can and see which one(s) suit you best.
