The TANDEMKROSS "Sentinel" Stainless Steel Captured Spring Guide Rod for WaltherA(R) P22A(R) is an excellent upgrade for your WaltherA(R) pistol. The WaltherA(R) factory spring is extra long and extends past the spring guide rod. This design requires a special tool to reinstall and makes cleaning your P22 a challenge. The TANDEMKROSS stainless steel guide rod for the WaltherA(R) P22 features a "captured" spring, doing away with the need for any special equipment and making your firearm maintenance simple.Because the spring is "captured," the TANDEMKROSS "Sentinel" Spring Rod also returns the P22 slide to the same position every time, reducing up and down movement of the slide and improving accuracy.This drop-in part is one of the best P22 accessories that will improve the performance and simplify the maintenance of your WaltherA(R) P22.
