Better than the stock pad, but requires fitting - TANDEMKROSS PRO Extended Magazine Base Pad, Ruger MKII/III 22/45, 1-Round

These pads come with an optional system for assisting with ejection from the frame. Assembling the 5 small parts can be tedious and I don't understand why anyone would not want to use it, so it should be assembled from the factory. The front of these base pads protruded a sharp edge at the bottom of the frame of my Mk3 22/45 and were unusable without modification. I had to file down the sharp ridge along the curved front face and then buff the filework to get an acceptable finish. This should not be necessary to use these and should be addressed by the manufacturer. Once installed and modified it does the job and makes magazine insertion and lock easier and more positive. Rather than order more of these right away for my other mags I have ordered another brand to see if they are usable right out of the package.
