Puma/Rossi??

[jnyork]

A few days ago I traded into a like-new Puma Model 92 .357 with the 24" barrel which was exactly what I was looking for. Ordered a Marbles' tang sight and a screw kit, they didn't list Puma so I ordered Rossi thinking they were one and the same, but apparantly not, the screw kit has an entirely different thread, might be metric. Anyone here have a clue what screws I should order? Thanks.

That's a new one on me. They're supposed to be the "same" gun--"Puma" being merely the marketing term Interarms used in the 80s-90s for their Rossi 92s, then Legacy (LSI) acquired the name and distributorship for Rossis when they essentially "replaced" Interarms as Rossi's largest stateside 92 importer. Legacy kept the name (for both their new Italian 92 and 86 lines) when they and Rossi parted company three years ago and they switched over to Chiappa. Assuming your "Puma" is one of those older Rossis (all Rossis will say Rossi somewhere or Amadeus Rossi), try M&M gunsmithing--which is/was Rossi's domestic warranty center. SteveCO recently also had luck with one of the other (Legacy's former?) Warranty center--for a particular part--I believe, he recently posted on.

EDIT - the above said, the older Rossis (characterized primarily by the Interarms era--the original Pumas), did have "odd duck" metric dovetails--approximately averaging .390 for the rear right IIRC, versus the standard Win 92 .375, so your speculation about screw size/thread differences may be entirely correct. Also IIRC, Legacy (and other post Interarms Rossis like EMF's) dovetails were--or became--.375", so perhaps screws went non-metric as well.....AND it's noteworthy that Marbles ceased making its buckhorn rear sights for the older "metric" dovetail Rossis almost ten years ago,..so...?

I bought my stainless 24" octagon in 2011 and it came with the mounting screws in the box for the aftermarket tang sight, as for the thread pitch I have not an answer. My rifle is branded Rossi.

Got it solved, both screws are 10/32, called Marbles, they are going to send me the proper screws, good outfit to deal with.

Glad you got it solved. I wound up going to the local Ace hardware, getting a stainless (to match the gun) flathead screw for the top/front, and a black hex-head machine screw for the bottom/rear, and reshaping the latter's head with a hand-file, then 'milling' a new screwdriver-slot with a Dremel tool, to make what I needed. Your solution sounds better!

Ahem....

If your gun is the Rossi made Puma 92 previously sold by LSI (they now sell the Chiappa as their Puma) then Marbles told you wrong. The upper screw for the peep sight is a 10-32 just like the original Win. But, the lower/stock screw is metric, an M5 X 0.8.
I have used the marbles screw set in the past and what I have found is the threads are correct but the un-threaded part of the shank from just under the head to about midway down is tapered and too big for the hole in the stock so it binds up about 3/4 way in.
What I do is turn the taper off and then it works just fine.

That's what I found as well; my used Rossi/LSI didn't come with any screws, so I ordered a Marble's screw-kit for my generic Marble's/Taurus sight ($29 vs. $129, but no screws came with it), and the Marble's kit didn't fit. If I'd have spent all that extra money on the 'real' Marble's, I'd have gotten the same screw set, and been even less happy (the Taurus sight itself has performed flawlessly and is rock-steady). Anyway, the issue was with the screw-hole threads on the Rossi, not whether or not the sight was brand-name - either way the 'normal' screws didn't fit.

Ace set me up right, and someday I'll maybe get the 'real' ones like came with my new Rossi/LSI guns, but I may never bother - here's what mine looked like after the first 'fitting', and aside from some more edge-rounding, there wasn't much more I bothered doing...

Both screws are 10-32, I checked them myself with a machine screw out of my bolt bins.

Nope, A 10-32 will screw into the threads on the lower tang. But it's very loose. that means the threads are barely engaging. Try this. Screw both in from the under side sticking out. Now, which one wobbles in the hole.

Nate is correct (big surprise). If you look on Marbles' site, Standard Peep Sight Screw Set (right under the picture of the apertures 2/3 down on the right) they list the correct screw set for the Rossi 1892 as p/n 995002. They also list p/n 995002 with front screw: #10-32 x .342 and rear screw: M5 x .8 x 1.815 Metric. It is all about the details. I got Brownells' screw set p/n 579-000-101WB (Marbles p/n 995002) for my 24" Rossi (Braztech import made by Rossi in late 2008) and it worked perfectly.

[jnyork]

Well, I have the 995005. the front screw is 10x32. The rear is .172x50. The rear does not fit. I will see how the one fits that Brownells sends me, if it doesn't fit I will get the 995002 and try that.

The marbles 995002 set is the one that has the correct threads but the tapered shank may need to be thinned/straightened to remove the taper some.

It sure would have been nice if the powers-that-be just settled on ONE kind of threading standard, wouldn't it... I actually like 'metric', and it is easier to work with and do math with and so on, but if we're going to use it we need to move to it all the way (I know there are huge logistic downsides). The alternative is to continue for the next century to have two entirely different sets of specs for everything...
