Whua! Is this ok? (pics)

Found this under the upper strip of my S&W frame.

It’s an old 1905 Hand Ejector, 38 Special.

At first I thought it was flame cut, but later saw that it’s not exactly where it should be compared to other guns and pics. Also, the cylinder-forcing cone gap is as small as it gets. Besides, it looks machined, as if made on purpose.
What the heck is that? Is my gun safe? Other than that the gun is in prefect condition and shoots like champ. Would this be common on other 1905 S&W Hand Ejectors?
Thanks for your help.

In the old days, S&W put that oval shaped cut in the frame to prevent flame cutting of the top strap.

S&W finally figured out that even with modern hot Magnums, the cutting is self-limiting.
It'll get so deep and no deeper.
Eliminating the cut was a cost savings.

"Fouling cup" is the name, I think. Old Colts had them too.

Would this be common

I think so. My commercial model 1917 has it also.

I bought my M&P 3rd Change, also with a 6" bl, two years ago. I couldn't believe it when I saw the fouling cup. It's great isn't it? It's the mark of a different time. Even mass manufactured items had little touches like that. It's a great shooter.

Mine really likes the classic 158 grain LRN load. Old Fuff advised me that thoe old M&P's were sighted in at 20 yards.

Enjoy.
