USPSA typically updates the classification scores around/by the 15th of each month.

Another +1 for Dawson Precision sights. Black rear, fiber front.

Ditto on this. I shoot only factory ammo of various weights (115, 124, 147gr) and use a Jager steel guide rod and 13# ISMI spring in my G34. No issues in thousands of rounds. Only other mods are "-" connector, grip tape and Dawson comp sights.

Have Dawson's on my G34 and G17's. They have become my sight of choice for my Glocks over my previous favorite 10-8's. I prefer the fixed as they are accurate enough for the loads I shoot.

Try using the various Velcro backed shotshell cards out there. Just requires you to add a strip of industrial Velcro cut to fit your receiver and attach the card to that. Use them on my 870 for HD and they work great. Plus you can remove them easily when not needed. I use the Esstac versions from skdtac.com. They have 5 and 7 round versions available in different colors. There are others out there though to try as well.
