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.

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.

Thanks for checking out the 1911 Recoil Spring Replacement chart. If you have questions or comments please leave them in the comment section below.
Hello,
I am trying to find out what it would take to change the spring in a Colt Commander chambered in .38 super so that it would cycle the .38 auto/acp. I have an older Colt (1903 Pocket Hammer) that is chambered in .38 rimless auto/acp. I am trying to make it so I have no .38 super ammunition in my possession so as to avoid the mistake of getting a .38 super accidently loaded into my 1903 and blowing up a piece of history. Not to mention what it might do to me or whoever happened to be firing the pistol at that time!
I think it would be safer (for me and the 1903 pistol) if I had ONLY .38 auto/acp in my ammo stash, thereby making SURE there were no accidental chamberings of the wrong round.
Do you have any information about what spring weight/poundage/strength (? not sure what there right term would be) to put into the Commander so it would cycle the .38 auto/acp? Both cartridges are exactly identical except for the powder loadings so it should not take much to get the Commander to cycle the lower powered cartridge.
Thanks,
Matt
Matt, thanks for reading my article and for your question. I would like to refer you to a Wilson Combat web page that describes how to determine the correct weight recoil spring for your gun. https://shopwilsoncombat.com/Recoil-Spring-5-Full-Size-18-1_2-Lb/productinfo/10G18/

for Colt ACE? which recoil spring?
According to Wolff springs Website, you want the Wolff Part number 41914 or 42414. Try Brownells https://bit.ly/3bCY0dx
i have a Colt kit gun in ,.38AMU which has been converted to .38 Special in a way that stiill allows the use of the .38 AMU round which has the same ballistics as the .38 Spoecial. with both cartridges, the first round often will have a type 1 or type 2 malfunction. The rest of the rounds go off as expected. Can you recommend a recoil spring for this issue? I have cleaned everything including the magazines. Thank you for your assistance. rdc
Richard, thanks for the question. I would contact Wolff Gun Springs and ask them about your gun issue. Orders & Technical Support: 800-545-0077.
