See if you can find someone with a high-speed camera to video the ejection cycle. I suspect that the cartridge mouth is hitting a part of the pistol as it ejects. If the case is spinning end-to-end as it ejects, the case mouth is very vulnerable to this sort of damage.On another note: I'm still having THE SAME PROBLEM with the MAX that I HAD WITH BOTH OF MY LCP IIs.
Wondering if any of you other MAX owners are experiencing the same thing?
When the brass is extracted it significantly dents the case mouth. Not sometimes - every time.
Because I reload 380, this is a pain the back side. You'd think Ruger would fix the problem (it is a known problem) with a new LCP II design. But Nope!
I contacted Ruger about the MAX denting the cases, and they say it is normal and there is nothing wrong with the weapon. Here is an except from the email response they sent to me regarding my description of the problem and my request for the firearm to be corrected:
"Here is the information you asked for. I hope you have a wonderful day and thank you for your patience!
Seeing some distortion of the brass at the case mouth is completely normal and is pretty common with semi-auto firearms. Brass at room temperature is a soft metal, and when it is extracted and ejected it is also hot which makes it even softer. During ejection it is not uncommon for the cartridge to contact some part of the slide while rotating/spinning out of the gun. That contact will often “dent” the case mouth of the cartridge (picture below). This cannot be tuned or corrected and is not considered a problem with the gun."
I ran into a MAX owner at the range a couple of months ago and asked him about it and he said his MAX does NOT dent his case mouths. Go Figure!!!
Of the over 100 different semi-auto pistols I've owned in my life-time, I've run across this only a couple of times other than both of my LCP II's and my LCP MAX.
If another pistol of the same type doesn't have this problem, it could just be something like the position of the ejector. This may be made critical by the power of the ammunition, so try your pistol with his type of ammunition.
If the problem is ammo related, and you don't like the ammo that works, you will have to determine what to change on your pistol. Springs are the first thing that comes to mind, but the timing of the ejection is also critical.
