Hammer Strut Support(R) (patented)  for Ruger MK

Tested and Recommened by National Magazines (and hundreds of customers)

NRA American Rifleman Magazine Review:

March 2019, page 35

Owners of Ruger’s Mark series .22 Long Rifle semi-automatic pistols have long dreaded cleaning them due to the onerous nature of the reassembly process, which could sometimes result in a non-functional pistol....(Hammer Strut Support) precludes future incorrect reassembly. The patented U.S.-made Hammer Strut Support ....blocks the hammer strut from becoming lodged under sear spring stop pin
