I have a new Performance Center 380 EZ. I've taken it to the range once and was very surprised by the number of malfunctions I experienced with it, including the dreaded LRS Syndrome. Internet searches about the problem led me here.
I didn't think to write down the details at the time, but I fired about 250 rounds and experienced about a dozen malfunctions. Mostly the Last-Round-Stovepipe, but also a couple of failure to eject. I think the failure to eject may have been ammo-related because it only occurred with one particular type of ammo, and only when loaded 8+1. (I had taken a variety of flavors to try out.)
I'm grateful for all of the work you folks have done to research this issue, and for the information you've shared. It's surprising and frustrating that there seems to be a lack of meaningful support from the manufacturer for this problem, but I'm still interested in trying to get my EZ to function properly.
I agree with what seems to be the general consensus that the magazines are a problem. The springs were very light to begin with, and are already noticeably weaker than they were just one week ago. One is weaker than the other, and so light that the last round just about falls out on its own if you are thumbing them out. Mine do have the yellow paint.
Before trying to make any changes to the magazines, I plan to take mine back to the range and collect some data. I'm also going to contact S&W, although I'm not really hopeful that they'll be of much help based on what I've read here. At least it will be one more trouble report to add to their database.
Another non-LSR quirk is related to magazine insertion. Loading a magazine when the slide is locked open requires a very narrow "sweet spot" level of force. Not enough, and the mag won't seat. But too much force, and the slide moves forward on its own and chambers a round. It was so difficult to consistently apply this "just right" level of force that after a while I just gave up and made sure to slap the mag hard enough to make the slide move back into battery every time.
It also seems to require more force than it should to properly seat the magazine when the slide is already closed. Not really a problem, I was just surprised by it. I saw another post where someone else mentioned this same quirk.
