Recommended Use: Commander-Size 4.25" .45 ACP shooting 230 gr. hardball equivalent or standard pressure JHP self-defense ammunition with a power factor of 175,000 to 195,000 (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 1,000 rounds and the recoil spring every 2,000 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.

|Shok-Buff kit Commander 45 ACP||5/10/2013|
|Installed on my Colt Commander XSE had to trim spring a bit other than that I instantly noticed a bit of softer recoil upon firing. Spring much better than Colt factory. First time using Shok-Buff but now will install on all my 45s. Am pleased.|
