Wilson Combat Heavy-Duty Recoil Springs are made combat tough to repeatedly take a pounding yet show remarkably consistent performance every time a round is fired.
Keeping a fresh recoil spring in your pistol will dramatically reduce the pounding your slide and frame receive.

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.

|This is the spring I run in my STI 2011 9mm. STI actually recommends a 9# spring but I've tried springs from 9-12# and they all function fine with factory loads of 115 grain all the way up to the 147 grain. I settled on the 10# spring and a Wilson Combat buffer. The pistol functions perfect and this combo gives me the recoil impulse I like for fast rapid fire and overall feel and cycling.|
