Tiny crack on N-frame blast shield area?

[MuayThaiJJ]

Anyone know what this is and if it should be a concern? thanks

This was plated in hard chrome recently. I never noticed it before. Everything functions fine though.

That doesn’t look like a problem to me. That’s not a typical trouble spot so I took some photos for you. 
 

Here is what my 2 N frames look like in that area. 

 

HERE is what my Model 19 looks like in that area. My model 19-4 was made in 78. My N frames were 2012 and 2021.

 

Look familiar?

 

You have no problem. It’s just now you noticed it. 
 

Truth be told I got a little excited over that same spot on my model 19 when I first got it, but my models 10 & 17 look the same.

The frame lug is to keep the cylinder from falling off when you open it up.  Weird that it's cracked, but it shouldn't be a safety issue.  Unless it falls apart and out of the frame I wouldn't worry.

 

It should be an inexpensive fix as it's a press fit fit of a part that should be under 10 bucks.

Just looked at my Model 28 Highway Patrolman, it has something similar.

Not cracked. Part of the production process.

Thanks.  Looking at it on my phone it's hard to tell.  Parting line from the mould?

I am really not sure. It almost looks like the cylinder stop metal is pushed up from the frame while the metal is still malleable.
