Cautions and Installation Test Procedure

HOW TO TEST TO MAKE SURE YOU HAVE THE CORRECT RECOIL SPRING WEIGHT FOR YOUR AMMUNITION:  Go to the range with your pistol and a magazine that will positively lock your slide to the rear when you slowly retract the slide with the pistol empty. Load one round of the desired ammunition in the proven magazine, load the pistol and fire the single shot holding the pistol in your strong hand, but grip the pistol fairly loose. If the pistol consistently (5 to 10 shots is adequate) locks the slide to the rear, the recoil spring is not too heavy for your ammunition. A recoil spring that is 1-2# below the weight where you begin to have failures to lock open is ideal for your ammunition.

18.5 Recoil Spring
Slapped it in and from first magazine it is running perfectly. Very stiff, but smooth.
Amazing improvement
You really don’t think that 2 1/2lb of resistance would make a difference. Dead wrong. I ordered to replace a worn out weak 16lb spring and I couldn’t be happier. I have positive engagement EVERY SINGLE ROUND, period. It feeds anything with zero failure to return to battery. 1000% will be buying again for my wifes
Runs like a champ.
My 1911 was havin problems feeding the round completely into the chamber picked up one of these now it runs with out a problem feeds every time. Wilson customer for all 1911 needs.
Excellent Springs
My 1911 works better than ever. Next time I need springs I will be back
Excellent Spring!
I replaced my stock recoil spring with this wilson 18# spring in my Springfield 1911 and the reliability is even better now when shooting large amounts of dirty ammo at the range. No problems whatsoever. If it works this good at the range with large amounts of cheap ammo, I know I can depend on it in the field with premium ammo if the day comes that I need it.
Excellent Recoil Spring
I got this recoil spring with WC one piece full length guide rod and it is great! It has been so reliable that even shooting lighter ammo like the Cor-Bon DPX 160 Grain my carry ammo, the case still gets ejected and extracted flawlessly. It has been 100% reliable and the gun is more controllable, less felt recoil than the original 16 lbs or less recoil spring. I highly recommend this to everyone who depend their lives on 1911 pistols.. another great product from Wilson Combat
Key to combat reliability, Wilson springs.
The greatest 1911 still relies on a well tuned recoil spring to keep everything else in fluid motion. You might as well spring for the best, pun intended. Most advice suggests a change every 3000 rounds but Wilson springs maintain their form so well, especially with a guide rod, that you can easily double that. Compared to other spring manufactures, I would only take a 1911 with a Wilson recoil spring into a fight.
