So I've put roughly 275 rounds through my Gen 4 Glock 17. Bought it used and owner said they had put through about 500. Never had an issue with it and love the gun. So 2 weeks ago I decided to run my defensive ammo through the gun. Retiring the xdm 40 cal from nightstand duty and promoting the Glock. I ran several nags mags of gold dot 147 gr through it. Totaled 65 rounds of hollow point no issues at all. Then ran 50 rounds of 115 gr Aguila ball ammo and no issues.
After that I said if it's on nightstand duty I want to add a light. Got the TLR 1 installed. Now I wanted to run more mags of my defensive ammo through since adding the light to make sure that would not cause any issues. So I went today and fired 50 rounds of 147 gr gold dot with the light attached... no issues again. After that I decided to shoot some more but with target ammo the range sold. It happened to be 115 gr PMC ball ammo. I had 2 stove pipes within 10-12 rounds. Then the rest fired fine. Why did this happen? Was it because of the light being attached and the 115 gr doesn't have enough balls to make the gun cycle properly or what? I figure since the defense ammo fired fine I shouldn't really worry but I'm also wondering, why did this happen?
