Hello everyone. I have recently been handed down a quick draw 38 used in cowboy shows. It was my grand fathers and I know nothing about this gun. My father does not either he was one who got it first then he handed it to me. This 38 has a hair trigger. Now I have a two part question. 1 how can I figure out what make and model it it and if its cal or mag....and can I fix the trigger so its not so dangerous to have loaded due to the hair trigger. I was going to buy a trigger lock for it. I thank you for your time.
