This article provides information about the Glock 19 Gen4 and issues with the recoil spring.

Introduction

I am not a gunsmith, expert, or anything close. I am sure there are a lot more people with more expertise than I, but what is posted here are my experiences with the weapons I own. I also have some content posted about the GSG-5 and AR-15. I welcome all comments and please correct me if anything I have here is not accurate. The information below details some problem I had with the Glock 19 Gen4 stock spring.

Glock 19 Gen4 Problems

The first time I fired this weapon I used 3 magazines but had errors 1 or 2 times PER MAG! I had 3 failure to feed, and 2 stove pipes, and 1 fail to eject. I was shooting PMC ammo, nothing weak or reloaded. After doing some research online, it seems others had the same failure issues which were related to the recoil spring. Apparently, the same recoil spring is used in both the 9mm and .40 cal versions. The general consensus is that the stock spring is too heavy for the 9mm version and therefore the slide does not stay open long enough for the weapon to properly cycle. This was such a common problem that it was addressed by Glockmiester, who fabricated a replacement spring specifically for the Glock 19 Gen4. They come in various models and spring weights.

So, I ended up spending $30 to get a new spring and while I waited I examined the gun further. The video explains how the gold grease was causing some issues and once cleaned worked fine. The Glockmeister spring is a single spring version like the previous ones found in the Gen3 weapons. The comparison in spring weight is demonstrated in the video.

Conclusion

After properly cleaning out the gold break-in grease, the weapon has been cycling just fine. Regular gun oil held just find to the inside of the frame and it has been operating normal ever since. I do not actually have a need for the 13 pound Glockmeister spring, but keep it handy just in case.
