While this is not related to the courses of fire per se, I suggest that if the weapon being tested includes additional backstraps -- such as the Smith & Wesson M&P, Beretta Px4 Storm, HK P2000, and Walther P99 -- that the shooter be given a chance to try them, as how a pistol its the hand is often a factor in how well it performs, in their hand. In addition to the pistols mentioned above, also be sure to include the appropriate Glock, meaning the G22.
