Went home and cleaned up all three, but noticed this injury to my PPS:

Gun actually still functions properly, dry firing etc. without a hitch. But obviously I'm not comfortable carrying a self-defense gun with a known break in functional part. Guess I'll have to call Smith & Wesson customer service tomorrow. Would be great if they'd just send me a new part (taking apart the slide on this Walther is same as a Glock), but I'm guessing they'll make me ship back the gun to them for repair and probably a two- to three-week turnaround.

Glad I found that deal on the G27 last week ($339.95 +tax), looks like he'll be in the starting lineup sooner than I expected after a great practice today and injury to the previous starter at that position.
