This modification will remove the magazine safety from my Ruger 22/45, and make the magazines drop free of the mag well when the release button is pressed. In the first picture is the mainspring housing at top and then (L-R) are the hammer and strut, the stock bushing, and the aftermarket bushing.
The aftermarket bushing has two raised areas on it where the magazine safety follower and its spring used to ride on the factory bushing. Those parts aren't needed and they've been discarded.
Here is the new bushing in place. It is deliberately a tight fit in the hammer assembly, and it needs to be tapped into place with a plastic-faced hammer.
The hammer assembly has been put back in place in the gun and the hammer pin has been fully extended - without, I might add, disturbing the safety or the sear - I'm proud of that.
Add a couple of Hogue cocobolo grips and it looks just like the other "45s".
