Cautions and Installation Test Procedure

1) Is the flat wire spring compatible with a full length guide rod?
Yes-Only with the full length flat wire guide rod (#25GRFW). The inner diameter of the flat wire spring is smaller than a conventional round wire spring requiring a flat wire specific guide rod.

2) Is a Shok Buff required?
A Shok-Buff is optional on the 5” flatwire guide rod.  It is not recommended for use on the 4” kit since it can reduce slide travel.

3) Can I shoot +P ammunition with this kit?
Yes-since flat wire springs don’t lose their length over time like round wire springs they cushion your frame more effectively over time.  Flat wire springs also compress in a more linear fashion which makes them more tolerant of a wider variety of loads and grips.

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.

The best for me.
It was time for me to replace my recoil spring for my 1911 and since I have replaced several other parts in my pistol with with Wilson parts this was an easy choice and the Flat Wire Recoil Spring works great every time
Smooth working spring
Went to the range today and tried out my new Wilson Flat-Wire Recoil Spring with a couple of boxes of bullets. As with all Wilson products that I have bought in the past, Im am completely satisfied that I have purchased only top of the line parts for my 1911.
best 1911 recoil spring yet!
I have used this 17# flat wire recoil spring for 3 months, approximately 4000 rounds. The spring is the same length as a new spring, showing no signs of getting weak! Factory loads, reloads, handles it all, leaves empties in a pile about 9 feet away.
Great Spring
I ordered this spring for my sig 1911 as it was time to change the recoil spring after about 1000 rounds. It does decrease the felt recoil slightly, and now my 1911 doesnt throw brass directly at my neighbor at the range. I called before I ordered this product and was told that a shock buffer would be included but it wasnt. A little disappointing but still a great product.
