I always put a Wolff 18.5 lb recoil spring in every "new" 1911.

Another question...What weight (load rating) is recommended when replacing the recoil spring? What's CMP using?

It also just felt weak when racking by hand as compared to my other 1911s. But what do you expect from a new 40 year old spring (8-78 rebuild at Anniston). Interestingly the spring had open/cut ends on both ends, not a wound end like you'd find on a new spring. Makes me wonder if they just cut one to nominal length for rebuild? No biggie, new recoil spring is only like $7.
Exactly the same for mine. A 1 81 build.

Testfire planned for tomorrow, then I’ll worry about springs. 16# recoil spring is normal spec.

As I understand it the springs may not be of equal length to be of equal strength/resistance. Something to do with number of coils and strength of wire as they are made.
