I'll get some video up on this as well. I'll have to get the lighting setup just right with the camera to pick up the black. So, what we've talked about in a few threads here is when you rack the gun to make it live, set the striker/trigger, there is a slight wobble you can have front and back. The firearm is still capable of operating, but the trigger pull is horrible. So, I pulled the trigger group out of the fire arm and assembled the barrel onto it. the only thing that moves when this happens is the slide, spring and locking lever. The space is the dead zone when the barrel locks into the slide and there is about a 1/16th of an inch to go before the locking lever hits the barrel lugs. None of the striker assembly actually moves during this. The part that intrigues me about this is that the firearm does not do it when its not cocked. Now, if I take the back plate off and leave the firing pin in, cock the weapon, the fire arm does not have this little waggle, but then the striker is not cocked either. So, I load the striker by prying it back and wedging something in there, and still no issue. Weird. So, apparently it has to do with the striker and firing pin interaction. I'm guessing the spring on the firing pin has enough umph while the main spring is stretched out all the way that it is enough to kinda put the firearm in limbo for where it locks up. I'd think that possible a Longer main spring would allow it to keep the same overall spring recoil, but apply enough pressure while locking to overcome the firing pin spring. I've always noticed that this pistol starts easy and gets harder to pull back later. Now, as for the M series Pistol, I'm not 100% sure that would be the case being a different barrel lenght, so report in if thats the case. This really seems kinda trivial and silly in the long run and and I'd assume it would eventually eliminate itself. Thoughts?
