People always ask me about how often to clean their firearm. How often do I need to replace parts? Always clean and lube it after every session of shooting is what I always tell them. The number one reason for a firearm malfunctioning is a dirty gun! 9 times out of 10 every gun I see, this is the problem. Following is a list of the parts that would wear out the most and you would likely have a malfunction if there is a part out of spec.
These parts listed below will be the ones that you would most likely have to replace (depending on type of use, rounds, and environment.) These round counts are suggestions from Glock. If you keep it clean after every use and oiled you should have no problems with your Glock lasting a lifetime. One suggestion people always ask me is about how much oil/lube? I say with a Glock less is better. You don’t want to put too much, you can weigh down your action and it will drag and malfunction.
A clean gun is a happy gun!
