I was watching Guns & Ammo T.V. a couple of weeks ago when the Ruger Mark III was used in the "Torture Test" segment. The two guys took a brand new Mark III out of the case and played baseball with it. One guy pitched it and the other guy nailed it with a bat. after doing this 7 or 8 times, they inspected the damage.
The barrel was slightly bent, so the tried to straighten it out, which they were able to, then they test fired it. Damn thing worked after all the abuse they put it through. Pretty impressive.
When I get my PAL, the Mark III is on my to buy list.
