I noticed that same thing in my Permit to Carry class this summer. I was the one closest to my 21st birthday, still being 21, and was the only one with a wheel gun. Everyone else was lugging around plastic boxes with plastic guns inside. M&P's, XD's and Glocks for the most part as far as I saw. I pulled out my SP101 and loved some of the double takes. I got to see about half the group shoot, and will say that I was in the top 10% as far as small/consistent groups went. Everyone passed, but there sure seemed to be alot of "patterns" rather than groups.
Made my day!
