Off The Grid

I just purchased a dove tail RMR slide adapter and wasn't expecting much of it. as it turns out, the dovetail socket in the full size glock seems to be tapered in the center (should I say "bowed"). You remove the rear sight with a punch and a hammer and then drive this adapter plate in. I had expected it would slide in and then get locked in place by the set screws. Not so. it is really really snug and the set screws seem superfluous. I managed to get it within 0.010" centered as measured with my dial indicator.

RMR seems to be the most prevalent and fits full sized handguns. The RMSc is slightly narrower for compact handguns like the G43x which has a 22mm wide slide. Keep in mind that if the sight is too wide, it may snag on clothing when you draw to fire.

For reference, here are the dimensions of the different mounts.

If you want to mount a reflex (holographic) sight on your pistol, you need to get the slide machined to hold it. Ahhh but glock sells newer pistols in the MOS (Modular Optic System) with a recess already machined. The problem is that they created their own standard and you need an adapter plate to convert the Glock recess to fit your sight... so they sell an adapter plate for Docter, RMR and RMSc. To me this is ridiculous because it's just more parts to move around or vibrate loose.

The next few posts will be about pistols.

The Chicago Mercentile Exchange pulled a trick to suppress the price of silver a few weeks ago. They increased margin requirements and forced a lot of small fish who'd bought silver on margin to pay up. Since most players couldn't cover the margin call, they were forced to cash out. This sudden glut of silver on the market suppressed prices. But it was only temporary. The price is back up to $90.47/oz now. All they did was delay reality by pulling the rug from under a few players.

How to spot fake silver coins.

I remembered an old story about my daughter from many years ago. She had drawn a picture that I thought was really good. I suggested we send it to gramma. She placed the picture in the flat bed scanner and I scanned it with her watching the light move from side to side. I emailed the picture to my mom and went on with life. about an hour later daughter came thru the computer room and picked up the lid on the scanner and said "oh look gramma sent it back already".
