It should be noted that the thumb safety and the grip safety act in two different ways. The grip safety merely blocks the trigger, while the thumb safety forces the sear into engagement with the hammer and prevents movement. Also, the thumb safety nestles into a semi-circular cut in the hammer, so that even in the event of catastrophic failure of the sear, the safety should prevent the hammer from falling (although, in this situation, the hammer would fall when the safety was disengaged)shooter1 said:Yep,
I have a duty holser that disengages the thumb safety on my Pro Carry. Due to the fact that there is still the grip safety and the trigger guard is protected by the holster, I don't loose any sleep over it. What about the Glock, does anyone concern themselves that the Glock has no mechanical safety? If the Glock is no problem, it's for sure the 1911 with the thumb safety disengaged shouldn't be.
