I took my faithful and trusted CZ 75 with the Kadet Kit to my range this morning. We had our 5 th straight weekend of snow falling but I slip and slid and skidded my way to the range anyway.
For much of the past month and a half I've been working on my one-handed bullseye form. I haven't given up on bullseye but I've signed up for a CCW class on the same day as the next 2700 match so I will not be competing for another month.
I've also returned to going to the gym lately and just started a new phase to my program. Friday's workout was upper body and I was working it. It's not unusual for me to have day-after muscle soreness but I really blasted my upper body and have a second day's worth of chest, shoulder, arm and back soreness. I really felt it when trying the support hand wrist lock.
I now know why the "reverse Weaver" is the term for this. You can not get your wrist lock in position with the gun-hand elbow locked. You can have both bent, for "guard" or both partially extended for "partial" but full extension is support arm locked out and gun-arm bent.
I'm sure I still have a lot more to learn about this position before I can even think I'm close to doing it right but, yes, it DOES help reduce muzzle flip and gets your gun indexed for another well placed shot faster than what I had been doing. You don't need to try and squeeze the gun between the hands, either. The wrist lock acts to reduce muzzle flip by working at the other end of the 'lever'. The soft webbing of your hand absorbs more energy, too, than trying to line up the hand/wrist/arm bones when you properly index the gun in the firing hand.
Prior to this I would consider what I did a "shallow" grip. The backstrap was normally on or close to the bones of my thumb. Only recently in bullseye shooting with my S&W 41 had I worked into a deeper grip. Middlebrooks' use of indexing with the second finger is a key component to achieving a proper grip.
A side benefit of using this "deeper" grip is that my long fingers don't try to wrap through and around the trigger. The finger is better positioned to use the tip to activate the trigger which will help with trigger torque.
One aspect occured to me. It seemed to me that the steeper grip angle of a Glock would work better for someone learning Fist Fire. It's not required as Middlebrooks is shooting a Witness in DVD 1. There was another club member with a G17 and I held that with Fist Fire indexing and it felt better to me than the CZ 75 or the other two guns I fired, an XD Service 40 and a 1911 clone in .45 ACP.
I plan to get my G 17L and 23 out for the next test fire.
