Default More Data

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.

I received the new (longer) springs from S&W. They do have yellow paint on them. After installing new springs, The issue is STILL there. Nothing has changed as far as stove piping and ejecting live rounds.

Scuff the top of your followers where the follower makes contact with the cartridge/casing to increase friction. That's the only thing we've found that "fixes" the last round stovepipe issue.

This may be a POSSIBLE fix for the 380 EZ stovepiping problem:

Let me start out by saying that I am not a gunsmith nor do have any affiliation with S&W. I'm a retired mechanical engineer who loves my S&W 380 EZ except for stovepiping the last live round. I bought the gun in June 2019 and run about 30% stovepiping (or ejecting) the last live round.

I have read just about everything on the internet regarding this problem and have tried spring spacers and different ammo. Nothing eliminated the problem but may have reduced it slightly.

As I looked closely at it I began to suspect the problem might be with the orange follower in the magazine. Basically I think the follower is too slippery on that last round and is causing the last round to stovepipe (or eject).

To see if I was right, I stuck small pieces of very fine sandpaper (220 grit) on the top of the follower on all four of my magazines. Tried it out at the range and had zero issues. Ran the 4 magazines through the gun for over 20 times total; everything worked just fine.

I will continue to test my “fix”, but would appreciate any feedback from anyone else who wishes to try it too. If enough others have success, maybe we have found a simple fix for this annoying problem. Perhaps S&W could roughen up the surface of the follower and fix the problem for good.

"Phil"
Phil,

I bought the .380 EZ for my wife. She has had the stovepipe issue and, on more than one occasion, has said "It only fired 4 times" (she loads only 5 rounds). One time the RSO thought she had a squib and actually disassembled the gun to make sure it was clear.

Anyway, I only found this forum last week and spent several hours reading through the threads on this issue. Friday we went to the range and I watched carefully as her EZ spit three perfectly good "last rounds" out onto the ground. There's my "Ahah!" moment. I've got work to do on the magazines.

I've seen Mr. christak's pictures of his scuffed followers; I may eventually go that route. But I was curious about the ongoing success of your solution of putting sandpaper on the follower. I have a couple of questions.

How did you attach the sandpaper? Double-sided tape? Glue?

Have you had any concerns over grit coming off the sandpaper into the chamber, extractor, or other parts? Grit, pieces of, or even the whole piece of sandpaper?

Have you had to replace the sandpaper? How long does it last, in terms of times the mags were used?

Do you think traction tape would work, or be too gritty?

You used 220 grit. I have some 400 lying around. Would that be course enough? I was thinking of sticking it on the followers with Command strips but I don't want to gum up the works before asking.

Thanks,

NukeRef
