As most of you guys probably know, when Ruger reintroduced the Bearcat it came with a .22 Magnum cylinder as well as the regular .22 cylinder. They did not put too many out before they quit making the .22 Mag. cylinder, and now they are outrageously expensive collectors items. I heard it was due to excess pressure. Now, the Bearcat is not a big gun, but it is a heck of a lot bigger than the NAA Mini Revolver, and that gun can be had in .22 Magnum. This is just me rambling, it is 4 in the morning and it has been a long night at work, but why in the world would the .22 Magnum have too much pressure to work in the Bearcat, but not the dinky little NAA Mini Revolver???? Am I missing something here, or was Ruger just being a little anal retentive on this?
