I always take a gun open and give a gun open, preferably grip first. If I am looking at a gun, I make sure it's pointed at the floor. If it is a DOA and I would like to try the trigger, I ask permission to dry fire. If not given, I immediately hand it back to the clerk (again, grip first). I was just at a shop this morning and the clerk opened the wheel on a Judge, closed it, and handed it to me barrel first and it gave me pause. I immediately opened the cylinder and checked it. What made me the most mad was that I told the guy I was looking for a small concealed carry, semi, 9mm and that was what he handed me. Then on to another place this morning, and they had about 10 semis (Glock and Sig) on display. They were so concerned with home-loaders, they never even talked to me and I walked out.
