Recently I bought a compact .22LR conversion kit for my UC2. That kit comes with only one magazine. While I had the sales guy on the phone, I bought three more. That makes four total.
(The odd thing is that the "bumper pads" for the compact Kimber line do not come from Yonkers, but from Montana. Strangely, all mine smelled like sausage...)
Having nothing better to do this morning after the gym except worry and fret, I decided to remove the standard bumper pad from the magazine in the kit. It looked simple, just a spring loaded plunger.
Try as I might, the pad would not move, so I called the "help desk" in Yonkers. I was told that sometimes they are a bear to remove. The pin has to be pushed down and forward. The guy wished me luck.
I tried every angle in the book, nothing, it was like the bumper pad was welded on. In desperation I squirted some Sentry Solutions Tuff Glide around the base of the pad, and let it soak in. Then I took the proper sized flat-blade screw driver to the base of the stock pad--and with my wife depressing the plunger with the proper size bit--I carefully tapped off the pad with a plastic hammer.
It took 30 minutes total.
Well, it got me thinking--how bad were the other three? I went to the gunroom with the bit and three bumper pads, and they all literally fell apart! It took three minutes total
! I depressed the plunger easily with my thumb, and the conversion bumper pads slid on like silk.
Now there's a bigger question. Why was the original magazine in the conversion kit so hard to change over? Is it over-sized? Is it crooked? Will it even feed?
Today I do not know, but I'm sure glad I ordered spares...
