I have a Colt 1911 Combat Elite that I purchased brand new about a month ago and have run maybe about 50 rounds on it and I have been very satisfied with it. I was playing with trigger today. I pulled back the hammer to half cock, depressed the grip safety and pulled the trigger. The hammer fell on the firing pin. I have a Ruger SR 1911 commander and a RIA 1911 9mm and tried to replicate it but both hammers did not fall. Is this normal? It sure doesn't seem like it.
