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 included but 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.; Specifications for Wilson Combat Flat-Wire Recoil Spring Kit Full-Size .45 ACP 614: Mfg Item Num: 614 Supplier SKU: 02514 The Wilson Combat Flat-Wire Recoil Spring Kit Full-Size .45 ACP 614 is a quality addition to the Wilson Combat lineup.
