I started with a Glock 19 shooting production in October of 2016. I showed up with just enough to get me through the stages and no idea how to plan the stage. My hit factors were low and i was really slow. Didnt matter. I had a blast and it got me started. If you plan on sticking with Glocks, get a holster that will accept a G34/35 so all the others like the 17, 19, and 22 will fit in it. Get magazine pouches that have different inserts like the DAA Racer or taco pouches that are elastic and accept almost anything. It will save you in the long run if you change pistols. Get a connector, comp spring kits, and an over travel stop for your glock. I ran Wolf springs with a 4 lb striker spring and have no issues. If your feeling like you want a enhanced trigger, OC custom triggers makes a production legal awesome trigger with all the parts I listed, shipped for 120$. 10 minutes on YouTube and your on your way. Heads up. This may be the start of your downward spiral into the madness that is USPSA
