JVG already got rid of his.
I think the guns are awesome, but totally not practical.
1) Ammo can't be had at almost any place that sells ammo, suhc as Dicks, Wal-Mart, etc. Only your LGS MAY have some.
2) Ammo isn't exactly cheap. And only have ONE manufacturer for that ammo doesn't help.
3) Some ranges won't allow the round to be shot in their indoor ranges, due to muzzle velocity exceeding their limit.
Otherwise, I think they're awesome. The felt recoil from them is excellent, in that it's no so much a recoil that makes the muzzle rise, but one that drives the gun directly back into your hand, planting itself more and more with every shot. That's the impression I got from shooting one when I was in Vermont not too long ago.
