Sigh....

This is my Bowling pin killer. An old Series 80 Colt Combat Commander. We have been through much together.

I'm really happy to push the timer button on you, but it always comes back to me shooting the pins. I love this thing for doing that yet now it seems the original grip safety and the trigger are not getting along. Sigh.... I have small hands for a guy and my first response was to order a Wilson Combat safety with the raised bump on the rear to insure I have disengaged it. One is on the way yet I ask you for guidance. 

I bought this new in 1986. I carried it for a long time. 

Help!
