Glock Compensator Information

So you’ve finally got your KKM Precision Glock barrel and comp comb, now what? Well for starters run good, high quality ammo through it. Lower quality ammo is also less powerful. This can cause issues with function as there is not enough energy to cycle the action and thus malfunctions happen. This problem is exacerbated the longer and heavier the setup is. For example: A stock Glock 26 with compensator will most likely function with any ammo. A stock Glock 34 with compensator might malfunction often with less powerful ammo. There are two options to fix this problem and one solution is a much better choice: shoot better ammo! We understand that this isn’t always possible when budgets and dreams don’t coincide. The second option to fix the cycling issue is to lower your recoil spring weight. Glock sends a 17 lb spring in it’s current guns. Spring weights are available from 10 to 20 lbs. Lowering your spring weight will increase reliability with lower power ammunition but it will also increase felt recoil because there is less resistance on the slide while it moves rearward.

This is a determination that you have to make and we can’t tell you which is best in your situation.
