A nice dude on the car forum i frequent inherited a browning HiPower 9mm from his dad. He doesn't want to sell it, but is curious about the value, presumably for insurance.
He mentioned that it attached to its holster like a detachable stock. From what the Wikipedia site says, that feature was discontinued after WW2. I am wondering about his legal situation/requirements with that pistol. Isn't the attachable stock a NONO, like a short barrel rifle? He is in California. I don't think there is much paperwork with the gun.
His father also left him a couple of other pistols (mauser & a walther) & a few rifles which he has to share with a sibling.
edit* Info he posted: Mauser HSC "01.32532" 9mm Short, Browning 9mm HiPower "8031" made in Herstal Belgium (Not sure exactly what model it is, but the gun does attach to its wooden case), Walther P38/P1 9mm "241494" "1494" "2/64" (has the orginal box that says it wasa West German Police Trade-In). And some rifles: Top-Remington Model 34, Winchester Model 94-30 WCF-"1249238", Not sure what the 2nd from the bottom is, & Browning Bar-22 Semi-Auto rifle.
