you seem to have made up your mind, i just want to let you know youre doing the right thing! hahaha. i have a P220R SS and i wouldnt trade if for anyting - a set of night sights, an x200, a couple safariland rigs and a bunch of novak mags are you are MADE!
i dont know what your plans are for carrying it - if its not a CCW or Duty gun i would suggest goin for the Stainless Steel version too. Its weighs more but its a truly amazing gun when it comes to accuracy. The extra weight makes it a JOY to shoot! im sure the non SS are awesome too, and if i had to carry it i would buy one. but mines a home defense gun, so when it comes out its comin out to do business.
my .02 - post up pics when you get it
oh, p.s. i suggest getting the hogue soft grips for it. i dont know if all 220s come with em, they should, they are amaing!
