Hammer Strut Support for Ruger MKII and MKIII

Hammer Strut Support

Finally, a solution to easily reinstall the hammer mainspring assembly into all Ruger MK pistols. Newly patented item makes reinstallation quick, easy, and always correct. After removing the pistol’s grips, the Hammer Strut Support easily installs in two minutes, in rear handle area, and remains in the handle. No special tools or experience needed.

Hammer strut can never again get caught under cross-pin: therefore the mainspring assembly cannot be reinstalled incorrectly-ever.
