Recommended Use: Compact / Professional Size 4" .38 Super +P full charge target or self-defense ammunition or .45 ACP shooting target ammunition with a power factor of 140,000 to 165,000 ( Velocity x Bullet Weight = Power Factor )
Average Service Life: 40,000 Rounds
NOTE: This is the standard recoil spring we install in our compact / professional .38 Super 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.
The new Wilson Combat Bullet Proof® Compact Spring Kit includes a hardened stainless steel full-length recoil guide rod, hardened stainless steel reverse spring plug and a chrome silicon 15 pound flat wire spring that will last many times longer than conventional compact recoil springs. The flat wire spring has a longer free length with more coils and resists tension loss much better than conventional round wire springs. The guide rod head is clearanced for compact barrel lugs and link.
The Bullet Proof® Compact Spring Kit has been extensively endurance tested and is a drop in-part with no fitting required. The .250” diameter rod can be re-installed at home or in the field easily without tools or using a takedown pin or bent paperclip.
Compatible with the following handguns:
NOTE: This kit is not compatible with any Colt or Springfield Armory firearm
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.

|I had occasional stove pipes and failure to feed on my Kimber, tried Wilson magazines which helped but didnt solve problems. I viewed the Wilson videos on You Tube and decided to replace it with flat wire recoil spring kit. I can say that after 500 rounds of different types of ammo and not one stove pipe or failure to feed.|
