The Tandemkross Blast Shield is a magazine disconnect replacement part built for the Ruger Mark IV 22/45, sold by Tandemkross. It replaces the factory magazine disconnect linkage, which on a stock Mark IV 22/45 blocks the trigger from moving unless a magazine is inserted in the grip. Removing or replacing that factory linkage lets the pistol be dry-fired or fired with the magazine out, and many shooters find it also smooths out trigger feel by eliminating the added drag the disconnect mechanism introduces. Because it is machined specifically for the Mark IV 22/45’s frame, it installs as a direct swap without any fitting. This is a popular trigger-feel and function upgrade for Mark IV 22/45 owners.
