Ruger Parts Their Magazine Disconnect Replacement is for Ruger Mk IV and Mk IV 22/45 pistols.

The primary feature is the "Blast Shield" that allows for the safe removal of the magazine disconnect feature, allowing the gun to fire whether or not a magazine is inserted in the firearm. The design also facilitates proper magazine alignment and shields the sear and hammer from debris. Unlike other fixes for the magazine disconnect feature, the "Blast Shield" design ensures magazines stay in proper alignment, reducing failure-to-feed issues.

The Cornerstone Safety Ledge for Ruger Mk IV 22/45 pistols is an oversized, 1911style safety.

This gives the same thumb placement preferred by many 1911 shooters. The hive Grip for Ruger Mk IV 22/45 pistols is modeled after TANDEMKROSS’s SW22 Victory grip.
