Glock 21 Gen 4 Problems

Glock 21 gen 4 is a popular handgun that has many fans. It also comes with a lot of problems and potential malfunctions. In this article, we’ll go over the Glock 21 gen 4 problems and how you can fix them yourself or send it in for repairs.

1) Dirty Magazine – How to clean your Glock magazines: First off, be sure to remove the magazine from the gun before cleaning! You don’t want to dump all that dirt into your Glock’s chamber. Next, use some mild soap on a rag or sponge and scrub down both sides of the magazine tube inside and out. Rinse well with water then let air dry completely before inserting back into the gun (so it doesn’t get rust spots).

Do not use oil to clean Glock magazines. Oil will cause the magazine spring and follower assembly to stick together when they’re dry, which makes them difficult or impossible to put back inside the magazine tube. When you can’t insert your Glock’s magazine without a struggle, then that means it’s time to replace it.

Next, wipe down the Glock frame with a rag or wet sponge to remove any dirt and grit that’s been sitting on top of it for days. Finally, use a cotton swab and some rubbing alcohol to clean out your Glock barrel (inside). Rinse well with water then let air dry completely before inserting the magazine.
