Hi David:

Thanks for your reply.

I don't have a model #, unfortunately. In fact, that's actually my first question in my post above, namely is her pistol a model 649? I don't know for sure, hence my question.

I don't have a camera handy, but her pistol is identical to the one pictured in the link that I included in my post.

I don't know much about pistol serial numbers. Are they like social security numbers in that you are supposed to keep them secret? Sorry, I am remarkably ignorant about these matters (but working earnestly to remedy my ignorance). The first three letters of the serial number on her pistol are CCW.
