when i first took my glock 30 to the range the reliability was alright, had a couple ftfeeds, as i continued to shoot it it felt like there was a bump somewhere in the feeding process. after the range and cleaning i hand cycled a few rounds. when hand cycling i discovered the the case mouth was snagging on the front of the magazine body, and it looked like the magazine fed directly into the chamber without even using the feed ramp. i called glock about the snagging issue and mentioned removing some material from the front of the magazine body, they pretty much agreed that it was worth a try. i removed enough material from the magazine body to prevent the snags when hand cycling rounds. another trip to the range and everything is running smoothly. Anyone else have the same problem?
