Kimber 1911 Recoil Spring Replacement Guide
The recoil spring on any semi-automatic gun is critical to the proper performance of the firearm. Each spring has a particular rating relating to how many pounds of force it takes to compress it by one inch. When a spring undergoes many compressions over time, it will become weaker.
Springs wear out and need to be replaced at a particular interval to avoid issues with the recoil operation of your gun. When a recoil spring starts to become weak, it may cause malfunctions as the timing of the slide cycle will be off. The weak spring will allow the slide to travel backwards too fast, possibly resulting in stovepipes, or Type 2 malfunctions. It is also possible that the gun will not go into battery, and will not fire as a result.
It is best to avoid these potential issues by replacing your recoil spring at the manufacturers recommended interval. See my tutorial on How to Replace a Recoil Spring on a Kimber Pro Carry 1911.
A 1911, when operating properly, should eject spent brass and throw it about 6-8 feet to the right and slightly to the rear (unless you have a left-handed gun). If it throws the brass further, this indicates the slide is moving too fast, thus throwing the brass with more momentum. This can be indicative of a weak spring.
I have collected information for Colt, Armscor and Kimber 1911 models in several calibers and barrel lengths.It is important to use the correct recoil spring on your firearm.
Here is a recoil spring replacement guide to help you know how often to replace the recoil and other springs in your 1911 pistol. I will be adding new manufacturers and information as I get it.
