well i'm new to the forumand i just bought my first glock the other day, a used 27 and i really like it. i did have one issue that confused me, the 9 round magazine without pinky extension (which i plan to cc) has a really hard time going in with a closed slide when loaded with 9 rounds and the slide is very hard to rack when loaded with the full 9 rounds in the magazine. i do plan on carrying 9 plus one but i'm scared the slide will get hung up after the first round is fired due to the tightness on the magazine fit. should i be concerned or is this normal? i did put 150 rounds through the gun with no issues and but i only loaded this mag with the slide already opened at the range. thanks for the answers in advance guys.
