+P in Model 10

[m4brian]

Shot the umc +P today. More zip, more blast, a tad more recoil, good accuracy. I did find a listing on another site, and it looks like it is about 1958/9 vintage. It cannot be earlier than that because it is marked model 10. I think the 5 inch barrel is cool. Shoots a bit to the right at 25 yds. Fixed sights of course.

From the S&W manual:

• “Plus-P” ammunition should not be used in medium
(K frame) revolvers manufactured prior to 1958. Such
pre-1958 medium (K-frame) revolvers can be identified by
the absence of a model number stamped inside the yoke
cut of the frame. (i.e., the area of the frame exposed when
the cylinder is in the open position, see Figure 2).

The M10-5 should be post 1962...

Then you left a digit off of the serial number you gave. If it were C415XX, it would be a pre model 10, made in 1948.

If it were mine I wouldn't have a problem shooting a modest amount of +P through it but would prefer standard pressure for most practice.

It does look like a digit was imprinted BELOW the rest of the number, so 415XXX might be it, which is the 58/59 time frame and definitely a dashed model number. 10-5.

M4Brian, I have a 5" Model 10-5 myself from around 1962. It's a great gun. You should be fine with +p ammo. With an endorsement from Jake'sDad, you should feel comfortable.

From the S&W manual:

Thanks. Just curious, which manual is that? Is that the Standard S&W Catalog that seems to be referenced alot.

A little more info...mine's a Model 10-3, serial # C57XXXX, according to S&W manufactured in 1961. It has a 4" heavy barrel. I feel pretty confident that I'll be okay with the +P now, but I'll try to get someone with a heartbeat on the S&W customer service line after they come back after New Year's.

I copy/pasted it from a manual I saved a while back, but it's the same as what's in the current manual available on S&W's website:

If you're looking for a factory endorsement of +P for your gun, it's in the manual novaDAK linked to.
