Here is the Ruger MkII4B (4" Bull Barrel) that I recently bought -



My plan?

New grips and a halo sight for starters!

I ordered 3 additional Ruger mags, Hogue wraparound grips (with thumb rest) and a Weigand 1-Piece Weaver-Style Scope Base, all from Midway and a Sightmark SM13003B Mini Shot Reflex Sight ($39.99 w/free shipping) from Ambient Outdoors -

I received the upgrade parts and got to work.

First was to install the Hogue wrap around rubber grips - I really like these on my pistols -



Before I removed the stock grip pieces-



And with the grips installed -



Next was to install the Weigand 1-Piece Weaver-Style Scope Base -



I tapped the rear sight out after I loosened the set screw -



And then installed the mount base (it goes into the dovetail). My mount piece needed to be filed some to fit.

This is before I installed the base set 1/16th screws with blue Loctite -



Then I installed the 7/64 allen head screws with blue locktite -



Mounted -



Then it was time to mount the Sightmark Sure Shot Reflex Sight - the package -



Some stock pics -







There are 7 brightness settings and 4 recticles -



Installation was very easy with the included allen wrench.
