Questions about guns

My name is Justin I live in MN, I have resently bought a smith and wesson 357 magnum and have lots of questions about it.

What are it origins, year, purpose, and ext.?
It does not seem to be timed right as long as pointed down it rotates cylendor fine but if turned up it does nothing why?
Is something missing from internal mechanism?
K frame?

Things I know about it are it has a four inch barrel, blued, square grips and checkering on them model 13-3 and possibly a k frame. I have pictures I will post also. The s/n starts with AJD 66xx

The last person who had it completely apart probably pulled the hand out of the trigger and didn't get the spring back on correctly. The hand or spring could be broken, but most likely it's just the spring off.

It definitely has been worked on; that hammer work is not factory. VA27 is correct. If you know how to remove the tirigger, it is just a matter of making sure the end of the mousetrap spring is on top of the small pin in the hand. Then check tension on the hand before reassembling.

Yes, it is on the K frame.
I don't have the book to look up the date made vs serial number but the Model 13-3 was introduced in 1982 so the gun was made then or later.

It looks like that revolver has been converted to a double action only. If you want to convert it back to DA/SA, you will probably need both a new hammer and a new trigger.

As far as origin, it depends on how far back on the S&W "family tree" you want to go. I'd start with the Model 10, the basic "duty" .38 spl. revolver that became an icon for police issue. The basic format began in 1899 and has evolved through names such as "Hand Ejector" and "Military and Police". The Model 10 designation began with the S&W numbering system in the 1950's.

During the lifespan of this great revolver many things have changed including in 1935 the deveopment by Smith and Wesson of the .357 Magnum. It was originally chambered in an N frame revolver, the larger frame used for .44 and .45. The .357 became so popular that Smith finally developed the mid frame (K frame) .357 version. The Model 10 was somewhat altered to handle the more powerful round. The adjustable sight "deluxe" version was the Model 19. The more basic "police/duty issue" is the version that you have.

Your gun was then modified for the highly utilitarian combat configuration of Double Action only (DA only) by cutting hammer, trigger and hammer spur. Slick draw with no impingement, fire only by pulling the trigger through the entire cycle, forgoing the "target" application of cocking the hammer first. Appropriate for a gun that also disposed of the "target" option of adjustable sights. The "use" of such a revolver is not the target range, but instead use by someone who thinks it likely to be in a gunfight. It is equipped as such.

And I see wear spring goes on hand but no springThe hand spring is inside the trigger.
The little pin on the inside of the hand rides on it.

Look inside the trigger for the spring.

If you're careful you can use the little hook on the mainspring to fish the hand spring up while you insert the hand. The trigger and hand are removed and installed as a unit. Might try Gunpartscorp for another mainspring.

How about a fireing pin can you buy that seperatly or is it only sold as a unit with the hammer
