The indoor range i go to rents the RUGER MARK-II for $10 an hour, so i know they see a lot of use. They are probably reliable, and not real fussy, or they probably would have went with something else. You should go to your range and look at what they have,and recommend. See if you can rent the one you like before you buy it, and take it for a test drive LOL.... The guys that run the range i go to will let me shoot pretty much anything in the shop, if i ask them real nice, and offer to sweep up brass, or help around the shop.
The Founders DID anticipate that arms technology would advance, that's why the 2nd amendment doesn't say "the right to keep and bear a musket".......
