Mountain Revolver -front sight?

[UltraCarry45]

Do you have to drill the hole in the sight or is it pre drilled?
I have a Mountain Revolver 629-3 that the front sight rocks front to back.

It will have to be drilled. Punch out the old roll pin, put in the new sight, drill it, put the roll pin back in.

Gunblue490 on the Tube says it's a 54/1000 drill. No luck at the ol' Ace Hardware. I'll have to check a few other locations, or the Big River.

What you need is a #54 drill bit, forget about places like ACE hardware you should purchase this online and buy at least 6 of them

These very small wire gage drill bits are very easy to break so what do you need to do is keep your drill very very steady unless of course you use it with a drill press, which makes it a lot easier

When you are drilling do not go all the way through.

Drill about halfway into the sight blade from one side then reverse and try to drill the rest of the way from the other side this will be easier on the drill bit and give you less chance for breakage

Here is another kinda unusual "Mountain Gun". A 629-1 with a square butt. I stumbled on this as just an ad for a ".44 Magnum revolver for sale".
Turned out to be one of only 40 square butt guns made on a special order by RSR Group. I lettered the gun and it was confirmed and shipped on Sept. 9, 1989. The SCSW #4 listed it as product code 103619.

Interesting gun! Did you install the cylinder release? I didn't think S&W used that style until the mid to late 1990s.

I noticed that also. I bought the gun from the original owner. Older gentleman. Not really a gun guy. It was his night stand gun! I guess I could replace it with a period correct one, but I feel that this is how it left factory.
I sent numerous photos with my letter request. I thought Mr. Jinks might comment if it was incorrect.

Neat revolver,
There was a thread about that variation a few years back that might come up if you do a search.
Can't exactly recall but if forced to guess I'd say they had some leftover Mountain Revolver barrels and old dash 1 frames,
If true it would support the case color hammer trigger instead of dash 1 flash chrome , the newer cylinder release and why the frame topstrap is not tapered to match the narrow rib.
