My S&W is a Hand Ejector. I don't know if it is after 1980 or not. Inside on the frame next to the yoke it has an X and then below that it has 22491 Then on the yoke it has 22491 with a large D below it. There is a serial number on the bottom of the butt or grip that is 99765 and it is a 38 S&W Special CTG. The barrel is 3" with a fixed front sight and no rear sight. I don't know if one used to be there but is missing? ANd, the blued frame appears to have only 2 screws. It is not a large frame gun and I need help with what I have? Thank you!
10-19-17 There IS a 3rd screw under the wood grip. The gun is a 5 shot and there is not any letters before or after the 99765 serial number. Trying to figure out how to add pictures.
