Do you folks carry with the chamber loaded and pistol ready to fire (safety on, of course), or do you carry with the chamber empty and thus needing to be chambered/cocked? (Please excuse the probably non-orthodox language - I'm a beginner.) If loaded, does constant tension hurt the striker spring? I am wondering about this, considering whether the LC9 (double action) would be better than the SR9C (single action). I much prefer the trigger feel of the SR9C.
