For 22 LR Ruger MK III & II, AMT Lightning, and most Ruger MK 1 Pistols
Reinstalling the Hammer Mainspring Assembly into Ruger pistols is a major Problem
The Problem: Hammer Strut gets lodged under Cross-Pin, allowing improper reassembly, making gun inoperable, and possibly needing gunsmith to repair.
But, the Hammer Strut Support(TM)
will install under the Cross-Pin
and remain there, keeping the
hammer strut from ever going there again!
The Hammer Strut Support(TM), below, solves the problem!
