Chamber Empty VS. Chamber Loaded
On February 16 and 17th 2013 Michael Iron Mikee Webb and the Texas Tactical shooters set out to gather data
on the efficiency of carrying a gun with an empty chamber vs. carrying a handgun with a loaded chamber.
104 shooters shot 4 strings of fire.
The Course of Fire consisted of 4 Targets at 3 yards. The strings of fire were as follows:
String 1. Starting with magazine inserted and an empty chamber and handgun in holster,
at the signal chamber a round and engage Target 1 with a Mozambiquee drill.
String 2. Starting with magazine inserted and loaded chamber and handgun in holster, at
the signal engage Target 2 with a Mozambiquee drill.
String 3. Starting with magazine inserted and an empty chamber and handgun in holster,
at the signal chamber a round using strong hand only and engage Target 3 with a
>Mozambiquee drill, firing strong hand only. Shooters were instructed that they could use
any safe technique to chamber the round strong hand only. This included using the belt,
holster, pant seam, etc. or even the Bianchi barricade that was conveniently placed in front
of them within arms reach.
String 4. Starting with magazine inserted and loaded chamber and handgun in holster, at
the signal engage Target 4 with a Mozambiquee drill using strong hand only.
Special Thanks to all the Texas Tactical shooters who helped to gather this data. Thank you to Ryan and
Jennifer for your work in compiling the data.
