Why would someone grab for a gun that's "very well concealed"?
The reasonable part of my mind agrees with this. Also what kind of mad man would knowingly put hands on someone with a gun, but there are crazies out there.
It would also have to be a multiple step attack to take the gun which would in theory give me ample time to react.
I also know cross draw is a mess in other ways.
I think I will just take peace knowing it's well concealed and the logistics of any potential attack would be way too difficult to pull off successfully and quickly.
