Put 200 rounds through my G29SF (recently acquired) this morning. I found one at Cabela's with factory installed night sites. 150 rounds of blazer 200 grain fnj's, and 50 rounds of 200 grain Hornady hollow points. I had to shoot indoors at the time of day that i went so i had to keep my velocities below 1100 fps. Functioning was flawless. My 10mm Glocks remain the most accurate of all of the Glocks i have owned and fired and that includes dozens over the last 15 years. I will hike with this little wonder this fall.
