Officers use a variety of levels of on duty and off duty holsters. I tested the time to draw and fire one round from each of these levels of holsters. Officers will also unsnap their holster, allegedly making the weapon more accessible. The time to draw from the four levels of holsters in an unsnapped condition was also measured. The officers were asked to place their hand near the holster for a start position. The measurement for this motion was the time it took the officer, in a reaction response, to move from a weapon in holster position, draw, get the weapon on target, acquire a sight picture and fire one round

In the research related to the combat tuck position, the officers were tested using the same holsters and under the same instructions, except the weapon discharge occurred in the close contact position.
