This is terrible advice, near akin to a curse. One Jimenez is a learning experience, more than one are hopefully gag stocking stuffers for fellow gun owners, and a collection is a clear sign of perversity.
You've got a cheap 9, learn from that. Get you a 12 ga pump shotgun, preferably a Mossberg or their Maverick, run some bird shot, buck, & slugs, maybe play w/ the shorties. As funds allow, piece together an AR. When you can, get a cheap Glock clone or any one of the decent compact service pistols on the market w/ common mags - S&W M&P, Canik, Taurus G2/G3 series, Beretta 92 or Turk clone, and then a PCC, or an AR mag block that takes those mags & an AR-9 upper.
