Saw mention at OldNFO's place that a friend had some pistols up for sale, one of which was an HK P30. I actually riffled through the Blue Book just to see what it said about the value of one in a listed 90% condition before yanking my own leash up short.
Yeah, it might be a screaming deal on a great 9mm pistol, but then there'd need to be a second one, and nobody makes a .22 trainer that I know of, plus the investment in new holsters, and sights, and a blue gun, and...
...and I really can't afford to switch carry guns* more than once a decade or so. Sigh.
*And that's the only use I'd have for a P30. Otherwise, that's money that'd buy a few top-break Smifs.
