Slight threadjack: What mods (other than the scope)? How much does this weigh compared to, say a standard MkIII or MkII Anniv. Edition? Do you want to get rid of the old adjustable sights? (-;Heres a pic of my Ruger MKIII.....this pic doesnt have the compensator, but it shows some of the aftermarket mods that can be done. This was a "Hunter" in stainless before mods.
If you were at the NES shoot, you should have asked to shoot it! Everyone who tried it giggled when they shot it. With its weight, the wdie target grips and compensator, it feels just like a pellet gun going off. You can drive tacks as fast as you can pull the trigger.
If you ever get up in the NH area, id be happy to let you try it out.
I shot competiton rifle for years, but got into pistol when i moved to NH. I recently got a 9mm thats alot of fun to shoot, but its nothing like the fun and cheapness of being able to burn 500 rounds of ammo for 10$.
