I'm really curious to hear how the Pinnacle 9mm conversions work out. I have 9mm guns, but only one .38, and it'd be kinda neat to have it use the same ammo as everything else.
I take it that since he's reaming a .38 cylinder, moonclips are totally necessary? With my 9mm SP101 you could just drop them in and they'd headspace on the neck. You could shoot them, but you had to pull the brass out with fingernails or knock them out from the front with a pencil. I take it that's not an option with a reamed cylinder?
Also tempting that his S&W L-frames can take the whole gammut of cartridges:
S&W 6-shot L-frame cylinders
Rechamber to 9x23 and shoot-
9mm, .38 super, & 9x23!
$250.00
That'd be pretty slick if you handload. The used to have a S&W 686 in .38 Super for some shooting games, since it could reload faster and whatnot, so similar idea. I could really go for a tricked-out 686 that takes those rounds, with a nice trigger-job, and maybe the barrel sides flattened like on the SSR version. Nice custom grips and a Tyler T-Grip, it'd be drool-worthy.
My main concern, as mentioned above, is the difference in bore diameters. Does it really matter much, or is it a pretty minor quibble considering the relative size?
Looking forward to hearing how this works for folks.
