Blast Shield Mag Disconnect Replacement
for Ruger Mark IV and Mark IV 22/45 Pistols.
- This little replacement part shields the sear and hammer from debris, improves magazine alignment, and allows your MKIV to fire whether or not the magazine is inserted. Replacing the politically correct Magazine Disconnect has always been a first step toward enhancing the performance of the Mark III and now Mark IV Ruger pistols. This new "Blast Shield" replaces the factory magazine disconnect on virtually ALL Ruger MKIV and MKIV 22/45 pistols.
- The unique design of the MKIV magazine disconnect replacement not only allows the gun to fire whether or not a magazine is inserted, it also facilitates proper magazine alignment and shields the sear and hammer from debris, boosting the overall performance of your pistol with a simple, drop-in part.
