These days KBI=Charles Daly. I don't think the KBI marked Hungarian produced HPs are coming in anymore. Charles Daly is importing the parts and assembling and finishing the guns in the US. BUT the CD isn't a direct copy of the HP. Looks like it but it's not.
The KBIs are great. Model should be PJK-9HP. If you see 9M anywhere on the model number, it's the same as the CD. Excellent copy of the FN right down to the crappy fixed sights of 40 years ago. I have one. Finish is nearly, but not quite as good as my dad's late '80s produced high gloss blued Browning. Accuracy and reliability is equal.........after you get used to the sights. Also, the sights use an older rear dovetail dimension. I'm told Sig P-series sights fit.
The price you specify: I've been out of the market for a while, but I bought mine in '94 for $250. I've seen them sporadically at gun shows for that but never less. I'd say if the gun is pristine, and waving cash under the guy's nose doesn't get him lower, then $275 is OK. BTW, these guns came with 2 13 round mags. If that's not what you're getting use it to beat him down. It's a pawn shop, so he probably paid an insultingly low price for it. Start off with $175 and work up from there.
