Help identify an S&W Model 10

[One1]

Here’s the front sight and what was messing me up. From the side the radius is a half moon, but it has the stepped ramp cut into the back half.

The front sight appears correct to me.

Wow! less than a full day since this was posted and already on page 2. Apparently, lots of revolver and S&W fans here. Just one of the things I like about this place. 

So far all the info given has been correct. S&W Model 10-7.  Made in approximately  1979. with a 4" tapered barrel. And yes, the front sight is correct. An extremely popular gun which S&W has made well over a million of.  Also one of the most popular LEO sidearms of all time all the way up into the 1990s.

The correct stocks would be the wooden S&W Service style and should be readily available at reasonable prices. However, most shooters seem to prefer something with a bit more meat to them. There are a ton of aftermarket stocks available in all types of materials. You will need a set to fit a S&W K-frame Square Butt revolver. 

+P ammo will be fine, but +P+ may be pushing it a little. It won't blow up or anything. But it will increase normal wear. Does anybody even make .38 Special in +P+? I don't recall ever seeing any? 

As for refinishing, I recommend a product called Blue Wonder.  I does require some mild heat. A blow drier is enough. But, if done properly, leaves a beautiful finish. 

BTW: be very careful about polishing before refinishing. Do not, weaken or damage, roll marks, seams or screw heads, round corners or dish out screw holes. I suggest working slow and easy by hand. No power tools.  A poor refinish job will drop its value considerably. However, a properly done refinish will increase the value on that gun. 

Anyway, that's a classic revolver you have there. Enjoy it!
