The manner in which members of the military carry their weapons, be they Israeli or American, has little or no bearing on what is prudent for civilians.
Well, it has and it hasn't. Like civillians and unlike the police, the military carry their pistols a lot and handle them daily but have a need to use them extremely rarely and use them only in dire emergency. So, they will take a bit of extra safety when handling the pistol in exchange for a bit slower draw time when and if they actually need the pistol. The difference is about half a second - not short, but not so long that it'd render the gun pointless, and it reduces the chance of accidents. Basically, a tradeoff. I wouldn't dissuade people from it, as long as they know the ins and outs of it.
If you're robbed at gunpoint and have not already drawn, there's no wonder bullet which is going to prevent the bad guy from squeezing the trigger at that point anyway.
