"I'm not sure why you think the boberg's slightly longer barrel is a game changer. All the chrono tests I've seen with that pistol seem to suggest there is precious little gained."
The 'game change' is that the sub micro Boberg has vastly more pleasant and controllable recoil than any other pistol near its size. He has a 45acp version coming out that
I think is very nearly the same size, but is apparently capable of rocking 460 Rowland
if you
really want to.
To the OP (if he's even still watching
) I would submit the R51 is the closest current-production gun to what you seek (an Al frame rather than poly, but with so much paint covering you'll never notice the different
), but I would not recommend buying it now unless you have made yourself
very familiar with the gun's anatomy, operation, and (numerous) known issues from the factory. I tore my gun apart at the store and looked it over for a good half hour before timidly betting on it, and at this point I think the only potentially important issue is the very rough chamber (thankfully it's also undersized, so I can ream it to spec and clean it up), but it would be very easy to fall for a lemon right now with out a lot of scrutiny on the part of the buyer.
Shooting it today was pretty much everything I hoped it would be (I've never fired a pistol anywhere close to as fast as I was blasting the R51, but it was still very controllable, if not very accurate in my unpracticed, flinch hands). My biggest regret is that the gun only has a 7 round capacity, so the fun lasts only so long
