Replacement for Grenaded Ruger Sp101...Crack in frame?

Analogkid · Jan 17, 2016

This is the Replacement Ruger Sp101Ruger sent me a little while back.

You can see the link here for the fragmented sp101 backstory.

I would be lying if I said I wasn't hesitant to shoot the New one they sent me.

Today I went to the range with a bunch of Blazer aluminum cased HP's ammo and shot it between a few guns. It isn't real hot but it all ran fine. I Ran several Remington 125gr sjhp's through it as well.

I get home and start cleaning them and I came across this in the pic below.

It sure looks like a crack in that part of the frame. I can catch it with my finger nail.

I know these are investment cast stainless so I am wondering if it isn't really a casting line that didn't get machined down. What do you all think?

That's just a casting line.

MikeJackmin · Jan 17, 2016

I'm no expert but that would be a very unusual place for a crack. I agree it's probably a casting line.

JohnKSa · Jan 17, 2016

You'll be happy to know that my SP101 has exactly the same mark in exactly the same place.

It looks like it could explode again.

It looks unsafe. Please send it to me for proper disposal.

Sure thing! Please send $600 as gift through paypal.

Jeepergeo · Jan 17, 2016

If in doubt, send it in for a checkout by Ruger.

Zaydok Allen · Jan 18, 2016

Yup. Casting line.

Waveski · Jan 18, 2016

Checked mine ; looks similar. I believe you are good to go.

Can't blame you for being a bit "gun shy". (pun shamelessly intended)

flightsimmer · Jan 18, 2016

If it were my gun I would get out my files and Dremel tool and clean it up.
But I just love doing stuff like that.

rcmodel · Jan 18, 2016

If it were a crack, it would be visible on the polished flats on the side of the frame.

So, it isn't a crack.

I know of two ways to tell.

Magnaflux

Polish it down a few thousandths, etch the polished surface with acid to reveal the gedges of the metallic crystal structure and examine it under a microscope. However, you are unlikely to get a microscope into viewing position.

I would not expect a casting line there on an investment casting. But you say more than one has it?

Find a machine shop that does dye check testing. Not as good as maga flux but it might give you a better idea.

Mine is smoothed with a tighter radius than the OP. I believe you are good to go.

Vern Humphrey · Jan 19, 2016

It isn't a crack, just a machining mark. But if you're worried, spray it with penetrating oil, and let it sit a while, then put it in the oven at around 200 degrees. If there's a crack, you will find the oil oozing out.

Waveski · Jan 19, 2016

+p ammunition is not recommend for use in oven above 185f.

Vern Humphrey · Jan 19, 2016

Dang! So that's what made the holes in the side of the oven! :what:

Mosbyranger · Jan 19, 2016

I've been following both threads regarding your SP101. I'm glad to see Ruger do right by you, not surprised, but glad. Did you ever get any feedback from either Ruger or the ammo manufacturer (Federal?) on the cause of the grenading?

I did not know that. Would you call that a poor man's magnaflux?

That is brilliant.

Waveski, I looked for a smiley emoticon, did not see it. I don't Vern Humphrey was talking about ammunition, only the frame of the gun.

p.s. edited to add.

Wow. I just looked up dye check testing and read the first paragraph here:
https://en.wikipedia.org/wiki/Dye_penetrant_inspection
Cool.

"Waveski, I looked for a smiley emoticon, did not see it..."

I do not use emoticons. lol is not in my vocabulary either. And I frown on "Smilies".

I figured Vern would get the joke. Tough room!

Sometimes I am a little slow.

Other times, a lot slow.

Take an emory board and buff it down some, then finish up w/ Flitz paste if you are super concerned. I can understand being "gun shy" on a replacement for your KB'd gun, but ALL Rugers I own have some stray mark here and there from the casting tree or machining. That's why you don't have to pay Smith or Colt prices
