Wilson Combat Shok-Buff Kit, Full-Size, .45 ACP 2G

Wilson Combat Shok-Buff Kit. 45 ACP shooting 230 gr. hardball equivalent or standard pressure JHP self-defense ammunition or 10mm shooting target ammunition with a power factor of 175000 to 195000 ( Velocity x Bullet Weight = Power Factor ); This is a balanced kit containing two SHOK-BUFF buffers and one heavy duty recoil spring. The SHOK-BUFF should be changed out every 1000 rounds and the recoil spring every 2000 rounds. When the SHOK-BUFF buffers are gone it's time for a new kit. It's a great way to remember your recoil spring changes. NOTE: Our recoil springs have a closed coil on one end to help them seat firmly on the guide rod. The closed coil end can be identified by its two close windings and narrow inside diameter. For proper installation slide the closed coil end over the guide rod stem this will leave the open end of the spring against the recoil spring plug. Improper recoil spring installation can lead to erratic cycling and possible guide rod damage.; Specifications for Wilson Combat Shok-Buff Kit: Manufacturer: Wilson Combat Finish: Stainless Fabric/Material: Steel Package Contents: Wilson Combat Shok-Buff Kit Wilson Combat 2G 1911 Accessories
