Just got a new catalog in the mail from CDNN. Nothing at the $100 price point, but some "real" guns that are shootable if you acn bump the budget a bit. Staying under $300:
Taurus M85 in .38 Special -- $289 stainless, $279 blued
Taurus .327 Magnum -- $249 stainless, $229 DuoTone (blue frame, stsinless cylinder)
Taurus 651 "CIA" -- .357 Magnum, stainless $299
Taurus PT22 or PT25 -- $189
Taurus PT138 Millenium Pro (.380) -- $289 DuoTone, $279 black
Kel-Tec P-II 9mm -- $229
Kel-Tec PF-9 9mm -- $229
Kel-Tec P-3AT (.380) -- $209
They have a few others for under $300, too, but (to continue flogging the poor, dead horse) I just don't think you'll find much that's shootable for $100 or under.
Almost forgot -- there's also the Armscor M200/M206 series, which should be selling for between $200 and $250. Discussed here:
