If the letters HS are on the grips, this is probably a Herbert Schmidt- a low cost handgun made in (what was) West Germany. I believe these have not been imported to the US in some time, and parts will be scarce. Check with a gunsmith- some parts such as pins or springs can be made- gunpartscorp.com MAY have some parts available- but the cost of parts MAY exceed the value of the gun. Sorry-
Do an internet search for Colt SAA grips and be prepared for dozens if not hundreds of hits.
Check the markings on the slide, frame and grips.
