The question cannot be answered as asked. However, a generic answer is, most modern guns don't have external manually operated safeties. A few, such as Glocks, have a passive safety on the trigger. 1911 and 1911 pattern pistols have a safety near where your thumb rests. A few other guns have safeties also near where your thumb rests.

"My pistol is .40 caliber." "We were fortunate to find a manager of his caliber."
The correct term is cartridge, not bullet- and the answer will depend on WHICH .40 caliber pistol.
Yes, a 45 caliber bullet is bigger than a 40 caliber bullet. A .45 is0.45 inches wide in diameter and a .40 is 0.4 inches in diameter.
@ .05 inches
The model 19 is a 9mm only proposition. The model 19 is not available in .40 caliber, but the model 23 is the same size gun and it is a .40 caliber gun. Some people would say that the model 23 is the .40 caliber version of the model 19.
Caliber is in reference to the diameter of the bullet. A .40 (which is what I have) is .40 inches in diameter. A .50 caliber is .50 inches in diameter (half an inch). So a caliber is the inches in diameter. Not including the 9mm which I cannot stand
