Model 459 Magazine Disconnect Removal

First you take out the rear sight assembly.

There's two plunger pins for the elevation access, you push them in and angle the sight so they don't pop right back into the holes, then lift the rear of the sight up to clear the cut-out and slide it out to the rear.

There are three spring loaded plungers to keep track of, be careful!

Then you remove the screw that nominally retains the rear sight ears.

Then the rear sight ears just slide out of the dovetail in the slide.

Yeah right.

Archimedes to the rescue!


The direction Marv pushed it out unmasked the firing pin block first.

Except for leaving out the plastic plunger and its spring, assembly is the reverse of the disassembly.
