Detailed Description


Recommended Use:  Full-Size 5" 9mm or .38 Super shooting full charge target or self-defense ammunition or .45 ACP shooting target ammunition with a power factor of 130,000 to 150,000 (Velocity x Bullet Weight = Power Factor)

Average Service Life: 20,000 Rounds

NOTE: This is the standard recoil spring we install in our full-size .38 Super pistols.

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.

These enhanced, chrome silicon steel recoil springs resist taking a set even after thousands of compression cycles for improved performance and reliability over standard music wire springs.  They are the top choice of competition shooters seeking the longest in spring life.

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.
