Unknown slide? thoughts?

[cooperod]

Hello, I ended up with this item in a firearms auction with other items I actually wanted, and I'm not sure what it is, but sure looks like a semi auto slide but has no internals other than 2 set screws on top.
Its stainless steel, not plated as it appears in the pics.
Any ideas would be appreciated.

Heavy underlug for a S&W 586/686 or Colt Python? IIRC a name might be "Jarvis", but it's been awhile since I've seen one.

I have one of those for my 586. Made by Jarvis
Mine is square on the bottom.

Dang I think you guys are right! This one has nothing stamped on it.
I also did not see a stainless one after searching Jarvis. Any market for them now?thank you!

I used the barrel weight when I was shooting PPC. I never bothered to take it off.

Toss it on the EE in handgun parts, some one may want it.
