My Ruger SP-101 has a blemish!

There is a lump of metal at the bottom; trigger end of the cylinder opening, at the rear; grip end, left side only. That is when hand held for shooting.
It projects perhaps 3/32 of an inch from the flat surface of the frame. It appears to have had some machining done on it, in that it may have been cut or ground away forming a "hemisphere."

That is one half of a circle; the diameter of which travels up and down -vertical when held in the hand. Approximately 3/16 in. in diameter.

Is this excess metal from the frame blank that Ruger does not want to have costly human labor remove, or does this "wart" have some purpose?

What is it?

Can I become a surgeon with my Dremmel and remove this eyesore?

It is the cylinder stop.

It keeps the cylinder from falling off when it is open, and you beat on the ejector rod with a stick of oak firewood!

I would not recommend removing it with your trusty Dremel tool.

Thanks Rcm.

Just goes to show you. I thought the mechanism in the ejector / extactor would be adequate for that.

I might press on the rod heavily, if I had to, but beat on and hard enough to cause the cylinder to fly off; not part of my Ranger training!

Ranger training or not, I still wouldn't grind it off.

Seriously, it takes the load off the cylinder crane & ejector rod internals when the cylinder is open.
