So I've owned a few 40's over the years... but today I ran into an issue. I bought a nice 40 last week--when I pulled the BA today I found out there is no index pin in the frame. Normally not a big deal, but this one looks different.
Here is a model 40 with serial number starting 357M--has a standard DW pin.
and here is a model 40 with serial number E00--notice the large hole--under magnification it appears factory.
Anybody else have an E series they can pull apart and check the pin for me? I may have to make an index pin if this is not factory.

Shoot,
To my knowledge I had this on a 15-2 once and they are only roll pins. I think I had one sent from CZ so I did not guess on the pin size.

I had this happen on my 715 a couple of months ago. The roll pin was stuck in the shroud. I was able to fish it out with a pick and this re-installed it in the frame with Loc-tite blue. I don't expect to have it happen again.

The problem is the hole in the frame is larger than the hole in a shroud... almost like the frame needs a bushing to hold the pin in place.

That's odd. Perhaps the PO drilled it out for some reason. Sorry Mike, but I'm not going to pull mine out just to check it.

Not to be stupid Shoot, but would the shroud have enough tolerance left to drill an equal hole that would match a roll pin to the current frame hole size?

I'll check my Palmer 740 when I get home tonight and let you know what I find.

I don't want anybody to pull the pin--just the shroud to see what the pin looks like in the frame.

I would--but I have a few different shouds and would like to keep them original.

I would give up on the model 40, it can't salvaged. Just send it to me and I will dispose of it properly. Oh, I will need to dispose of any shroud and barrels too.

I'd say you either have a factory reject that shouldn't have gone out the door or some no-mind drilled it our for whatever reason. You basically have one choice – make (or have it made) a step pin that will press-fit the frame ID and slip-fit the shroud ID. Should be pretty simple. Here's a 40 with the same E00 prefix:

I like Harlys' step pin idea, it would be the safest and cleanest way to do it without doing anything to the frame or shroud.
Anything worth doing is worth doing well.

yep, step pin was my first thought--just wanted to see what some other E00's looked like.

Gee, Thanks SHOOT , now I'll have to go re-sight in the iron now that
I pulled the shroud off 
….that's OK , needs the dust blown out anyway.
I'm not gonna be much help here, mines a MB00 and has the pin.
Have you tried a roll pin yet ( I bet $ you have but just asking)
sure looks like that hole is stepped to me.
Is it me or dose Harley's pic look like a step pin ? look at where
the pin and frame meet, I see a ring.

It's a very small counterbore at the face of the hole. They probably put it in to ease the insertion of the roll pin. You can also see it in Mike's first photo. What you see is a shadow where the bevel is. It looks like they went too large and deep on Mike's gun. Regardless, it's a simple fix.

My Palmer 740 is not a step pin. The pin measures .0975 and looks to match Shoot's first picture. The pin in my 715 measures .0940. HTH.

Not sure on mine though when it comes out I will check it! Looks like you have the Step pin to make as the only option on this one! Look at the Barney on the harly's, i am liking that stuff. Let us know how it works out!

I pulled my E00# shroud this AM to check. I don't have the camera available but its a duplicate of harly's, to include the slight barney. Yours is noticeably larger as it nearly touches the cutout for the crane.
Technically, the glass is always full; half liquid, half air....

That's an interesting problem. I have one shroud that sticks sometimes to the pin while the other shrouds don't. Good luck.
