Recommended Use: Compact / Professional Size 4" 9mm or .38 Super shooting target ammunition with a power factor of 125,000 to 135,000 ( Velocity x Bullet Weight = Power Factor )
Average Service Life: 40,000 Rounds
NOTE: This is the standard recoil spring we install in our Compact / Pofessional 9mm pistols.
This Wilson Combat innovation solves the issue of recoil spring fatigue in compact 1911 handguns and will greatly enhance overall compact pistol reliability.
Compact size 1911’s are noted for being extra hard on recoil springs and as your stock recoil spring takes a set and tension is reduced, the magazine spring will struggle to keep up or a last round feed malfunction can occur.

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.
