I'm going to shoot and IDPA match Sunday and there is sure to be a tactical reload in one or more of the COF's
One book i have suggests that you keep you eye on the threat with a round in the chamber, drop your left hand down to your belt/pouch/mag holder and grasp a fresh mag (call it #2) between thumb and forefinger, then raise your left hand with the mag up to your weapon while shifting the mag to a position between your index and middle finger where you catch the first magazine as it is being ejected between thumb and forefinger; you now have two magazines in your left hand and you insert the one (#2) held between the 2nd and third fingers into the mag well and slap it home with your palm, then you drop your left hand back down to your belt, vest or pants pocket, whatever and stow the first mag, then you raise your empty hand back up to the weapon and re-establish your grip and sight picture. (Tactical Pistol Shooting, 2nd ed.)
That's two downs and two ups and you have to simultaneously handle 2 mags in one hand.
How about starting with your normal grip, slide left hand under the mag, drop the mag - you still have a round in the chamber - drop your left hand down to your pocket/belt pouch/whatever and stow the partially used mag, then slide over to your mag pouch and grab a fresh full mag indexing your index finger along the front of the mag and raise it up to your weapon, insert it in the mag well, tap it home and resume your grip.
That's one down and one up and you only have to handle one mag at a time.
Seems to me that the second method is faster and less prone to fumbles. Your weapon has only one round available for a very short time but the whole process is/should be faster.
What are your thoughts??
