Stopped in a LGS and found a Model 37 Airweight, 90% + condition, SN J333xxx. Asking $295. Is it worth it and is it safe to shoot? Being an Air Force vet I know there were issues with the Aircrewman.
No one on the internet can tell you if an individual firearm is safe to shoot or not.
To make a individual safety determination would require a hands on examination of the firearm in question by a knowledgeable person or a gun smith.
Generally speaking, model 37s in good operating condition are fully capable of safely chambering and firing any and all modern 38 Special ammunition that conforms to SAAMI specifications.
