Do you mean a Kahr P40? If so: List price: $739-$903 Gunbroker prices: $510-$610
Maybe someone else knows local CT prices. Probably will have to go look yourself for those.
UPDATE: (thanks niko):
OK, so you do really mean Kel-Tec P-40. Thanks.
"Unfired" may be a bit tough to find given that Kel-Tec apparently no longer makes the P-40. Used prices on Gunbroker are $295-$355 but only 2 of them appear to be listed at the moment, both used. Good luck
