If anybody's in the market for one Aim Surplus has a preorder for some $189 + $10 shipping. I've a always wanted one and these seem to be In good shape.
They've seem to have dried up and dont think they'll get any cheaper, so i ordered one to pop my C&R cherry.
That pistol is totally unique as the cylinder mechanism moves forward to form a closed gas seal around the cartridge mouth as it fires. That enables the revolver to be suppressed, too. Academy had the ammo recently but I quit checking on it so I can't swear to being in stock today.
