Love the XS v notch Big Dot on the G27 nice to have a headlight when you are 62.
Too bad XS sights have never won a major match… 
Whereas, my V-Dot Pro-Sight has won over 50 major titles including 2-IDPA Nationals along with National Police Combat Championships. Here’s a testimonial for the latter:
“At age 66 I just couldn’t see my Bomars anymore, so D.R. suggested I tryout his Pro-Sight® V-Dot. I used it to win the Second Chance National Police Combat Championships. I set new National Records for Low E.T. and I shot the FASTEST aggregate time ever recorded.” – Ken Tapp, OK
NOTE: It is VERY important to note that some ALL TIME SHOOTING GREATS were at the match that Ken Tapp won. Guys like JERRY Miculek and Jerry “The Burner” Barnhart, just to name a few. And the OLD MAN BEAT THEM ALL using this V-Dot sight picture:
