If you own a gun that won't shoot without a good firm grip, think seriously about whether you want your life to depend on it. My primary lineup for defensive carry is a pair of glock 19s rotated every month from carry to range us. I have an aftermarket barrel that I switch back and forth every month to even the wear from range use. I clean each gun when I switch barrels whether they need it or not and replace springs every couple of years.
If you can limp wrist one of my glocks, I will give you a nice crisp $100 bill. At my range, this subject comes up every now and then with the crowd that hangs out there. I always ask someone to demo a limp wrist for me. I have not seen it yet. and the topic suddenly changes. I can shoot my glocks or either one of my Les Baers with only thumb and forefinger of the weakhand in contact with the gun, they all run mechanically perfect. You can't hit anything, at least I can't, but the guns work just like they are supposed to.
A long time ago, a friend in another precinct happened upon a stongarm three on one street robbery. An unobserved forth member of the ghetto social club doing the deed, hit him from behind with a piece of gas pipe. He got his scalp opened up, and right arm broken in two places. With broken arm, he retreived his piece but could not grasp or deploy it. He tried to transfer the gun to his weak hand but dropped it on the ground. He picked up the gun with his left and took down two of the boogers including the one the hit him from behind, despite the grip being slippery from blood. The gun in question was a Colt revolver not subject to mysterious internet malady of "limpwristing"
But ask yourself, if your gun was slippery with blood and you could only get a partial weakside grip and it would not work perfiectly, why would you carry it and use it go defend youself and family?
My wager? You lay a fifty on the bench, I will cover it with a hundred. If you can limp wrist one of my ugly glocks, you get both. If you can't, the fifty belongs to me. The best that I have seen is a "expert" and loudmouth finally put up a five against my ten. Which became mine 50 rounds later.
