I have mentioned this drill before as a good test for a new gun, or for your carry proficiency. I always encourage people to shoot some kind of test before choosing to carry a gun to see where they are at and to see if the gun is up to the task. This could be a quick and easy test for that, though I would actually prefer something like the ATF or FBI quals. The idea being if you and your chosen gun combo can't pass the test, you need to pick a gun better suited for shooting as opposed to carrying, or do a lot of practice. Mostly I posted this because I like seeing lists of known shooters and how they performed on similar tests. Also there is some cool video involved. Wilson Combat | 5x5 Handgun Skill Test
