butchb243: Competitive shooters have been removing the hammer blocks from S&Ws for over 60 years. You would have to drop the gun hard enough to shear the hammer in half for the gun to fire. The hammer is the strongest piece of steel on the S&W. Your finger can slip off the hammer while cocking the gun all you want. As long as the trigger is not back the gun won't fire.
Lot's of people on this board carry Kel-Tecs, older CZs, MAKs, series 70 1911s. All are FAR MORE DANGEROUS if dropped than a S&W without a hammer block.
