Colt, Rock Island, Springfield and 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. I have created a chart below listing the correct replacement recoil springs for popular 1911 models.
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 (the slide is all the way forward), and will not fire as a result.
A friend recently recommended this CLP (Cleaner, Lubricant & Protectant) Gun Oil and I love it! It is non-toxic, non-staining and non-scented, which means I can clean my guns in the house without the terrible odors of solvents! I am now using it to clean and lube all my firearms.

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.
