If you are not comfortable enough to carry this weapon with one in the chamber, You need to do one of four things.
1: Practice at the range until you are. Agreed
2: Chose a different firearm and practice with it until you are. Also Agreed
3: Carry a knife Yes, in addition TO your firearm
4: Don't carry. Not sure I would go THAT far. I would rather see someone carry with an empty chamber, than not carry at all...
The point is, Get comfortable enough so you don't hurt yourself or someone else unintentionally and so you can properly defend yourself. How many police officers do you think would tell you they do not carry with one in the pipe. There is a good reason for the answer. Practice and training, no compromise.
