Hey everyone. I have a Gen4 19 with about 280 rounds through it, with one FTE from a WWB round. That was with the 03 spring, and since then I've fired around 75 rds with the 04 spring with no problems. I haven't carried the gun yet, and just bought some Gold Dot 124gr +p for it. The first 20 rds I put through the gun were standard 124gr Gold Dots and they ran fine. How many rounds of the +p ammo would you run through the gun before you deemed it trustworthy in the gun? I know that's an opinionated question. So far, I trust my Glock, and I trust the reputation of the Gold Dots. Does anyone have experience running this ammo through the gen4s? I only bought 60 rounds, since money is a little tight right now. I'd like to carry the gun topped off with 16 rounds, and have a spare mag of 15, leaving me with 29 rounds to test in the gun at the range. Thoughts? Wanna kill these ads? We can help!
