Go with the Ruger. There is a good aftermarket in parts if you want to "enhance it" it a bit. I shoot mine
in speed steel competition. I get rid of the magazine safety and install a Volquartzen trigger kit.
Specifically--for a packin in the pasture and teaching the kids gun---get the Ruger 22/45 Lite. Catalog #
P45MK3ALRPFL. Warning--it comes with a threaded barrel from the factory. Sooner or later you will want
to accessorize your Ruger with a suppressor.
When THAT bug bites you, look hard at the Liberty Kodiak TL. I REALLY like mine.
