Smith61: Thanks for the insight. I always plan for the least common denominator; so I'm going to err on the side of getting some 10 round mags, and (gulp), loading 9mm FMJ just to keep the NJ boys in blue off my back. I really love my G17 and I don't want to buy a single stack 9mm just to satisfy some states restrictive magazine limits. Then again, there is the 5-shot Chiefs's Special in the back of my gun safe that should make anybody happy....LOL.
