Which guns are "safe" for carry? ie. Is the LCPII and a 1911 actually safe?

So this Taurus that goes off by merely shaking it, it probably unsafe right? http://ift.tt/2rLpVxF what features are critical for a carry gun, and how can I look this up / make the decision?I ask this because I'm impressed with the mechanisms and designs in use to prevent guns being dropped and going off (specifically the striker blocks in the M&P and Sig P320 combined with mechanisms to prevent the trigger bar from being pulled back due to inertia of a drop / impact).But is drop safety actually an important feature of a carry gun?I also own an LCP II, and pulling it apart, I'm not actually clear if it's drop safe. The manual explicitly makes clear not to carry the LCP II with a chambered round.I believe my 1911 Springfield Range Officer Operator isn't "drop safe", but I don't know what that means in the case of 1911s. I don't know how a "drop safe" 1911 works. But clearly lots of people carry 1911s.The CZ Shadow 2 doesn't have a striker block..So what makes a gun safe or unsafe for carry for you and how do you go about finding out that it lives up to that standard?I know striker fired guns and the LCPII are "half cocked", but.. if that hammer or striker actually falls, is that actually safe from being fired? via /r/CCW http://ift.tt/2qNxOFF
