And herein is yet another excellent example of the compromises one must be aware of, and accept, in order to make an informed decision regarding defensive firearms.I agree any handgun would be more dangerous in a screwed up holster like that but I can't see any way a 1911 would be as dangerous as a Glock in that holster.
"Point and press" arms eliminate the conditioning / training required to deactivate manual safety features, which is good. However, they do not discriminate between who, or what, is doing the pressing, which, as in this example, can be bad.
Arms that have manual safety features that must be deactivated in order to fire are far less susceptible to being discharged as a result of contact with foreign objects, such as a holster. This is good. However, these arms also require training / conditioning to ensure that the user deactivates these safety features prior to attempting to fire under stress. That can be bad, as some folks just won't dedicate the time to properly condition themselves, and may forget about the safety when they need to fire the most.
Pick your poison.
One of the endearing qualities of my beloved 1911's are the manual safety features. The 1911 WILL punish you for being stupid, ignorant, or a noob.
Fail to disengage the thumb safety? NO SHOT FOR YOU!!!
Weak grip that fails to disengage the grip safety? NO SHOT FOR YOU!!!!
Put your thumbs under the THUMB (:)) safety and accidentally engage it during a shot string? NO SHOT FOR YOU!!!
Comedy is watching SEASONED "point and press" shooters transitioning to the 1911 platform and inducing stoppages during competition because of "Glock thumb", "M&P grip", and "Whoops, I forgot about the safety." That wouldn't be funny, on the other hand, in a defensive scenario.
