On Limp Wrists

This is a good video, and it even presents some information that’s new to me

I was well aware of what a “Limp Wrist” malfunction is and how they work. Still I hadn’t thought about it in terms of how it relates to ammo. He notes that .40 S&W guns are difficult for him to limp wrist. This is likely due to the “Snappy” recoil of .40 S&W. The recoil curve “Snaps” the slide back before your wrist can break up and back and either cause the slide to short-stroke, or to catch the ejected case before it clears the ejection port and stovepipe.

This got me thinking about my Kahr PM45. Allegedly Kahr pistols need 200 rounds to break in. My first 200 rounds in my Kahr were no different than my next 200 and so-on. Still the recoil spring did loosen up considerably. That extra-stiff spring COULD easily cause a short-stroke. It got me thinking of myself in those first 200 shots. I was shooting for the first time a 20oz .45 ACP pistol. I had concerns that the gun might be more than a handful, so I had a LOT of tension on the gun, this allowed more energy to be transferred to the action and allowed for smoother cycling.

Also it makes me think that not only the added power, but the added recoil impulse makes +P ammo ideal for carry, given that both the shooter and the gun can tolerate the extra power.

Good to know, and be safe out there!
