Frames

[Bullrock]

I'm a newbie and recently purchased a SW66. I just know someone can tell me the difference between a j frame and a k frame?

Many thanks

The letters correspond to size...the lower the letter, the smaller the frame. The K frame would one size up from the J frame.

Also, in 38special/357 J frames have five chambers, K frames have six.

And... J frames use a coiled mainspring, while K frames use a flat one.
