Hey Osodog. Glad I helped in some small way. That's why we come to forums...for info sharing and ideas. I know I research crap to death when I'm making a big purchase, lol.
My VTAC is still running strong and I shoot it A lot in my local 2-gun matches. Unfortunately, as an update, the fiber optic rod in my front sight fell out. S&W is replacing it, no questions asked. But honestly...I'm thinking about running a set of warren tactical/sevigny sights instead.
Here's a few updated pics of how my VTAC sits nowadays.
