Folks, There are a lot of accessories available today, but the bottom line is that you cannot buy accuracy. Nothing takes the place of hard practice with a purpose. I recently reviewied all match results since March 2000. In the hands of a Master class Shooter, a stock G17 shoots as well as a tricked out race Glock with all the goodies. A composite of the best stages ever shot with a stock Glock provides a score of 36.99. A composite of the best stages ever shot with an Unlimited Glock provides a score of 36.12. Folks that's only 0.87 points difference! That's theoretical of course. In actual individual scoring, Tom Costanza presently holds both the Stockmeister record score of 45.61 AND the Unlimited record score of 40.19. Now that's only an actual difference of 5.42 points. Tom used the finest fitted barrel, scope mount red dot scope, etc., on his unlimited pistol, and adjustable Bo-Mar sights on his otherwise stock G17. In Unlimited, even the smallest improvement counts. However, if you are not in Unlimited, feel confident that your Glock is capable of near-Unlimited performance. The secret is practice with a purpose. Don't noise it around.
