1911’s in general, 9mm versions specifically

I did have an issue with the CS (which I purchased through the Staccato CPO program). The slide would not lock in the open position after the last round. I tried both of the magazines that came with it (OEM and "brand new" per the company). I eventually figured out that both magazines are the problem. (I put a C 17 round magazine in the CS and had no issues manually racking and locking the slide with an unloaded magazine.) The company sent me a warranty claim link, and I'm sure it will all be fixed. But this development isn't cool. I've had zero problems with the 6 mags I have for the C.

Anyone else have OEM mag troubles with the CS (2024)?

When I ordered the DPO plate for my CS, I ordered two more 15-round magazines. One of them had the same problem as above. WTH? Good on Staccato for the last batch (they just sent me 2 replacement magazines and said I could keep the defective ones), but why is this a problem?

That's pretty weird, and not cool. I don't have a CS, and haven't had any problems like this with my C.

Are you seeing any reports online of other guys having a similar problem with 15rd mags in the CS? If so, it would seem like a mag issue. If not and it's just yours, it makes me think the slide release on your CS may be just a bit out of dimension, where the floor-plate of the mags push up against it. But that's just a guess. Also, on the user-error side of things, be double-sure that you're not riding the slide release in any way.

The only times I've had similar problems with other guns, has been when either the mag springs wear out, or the lifter shelf on the floor plate wears down and doesn't have enough surface left to engage the slide release fully. Had both happen a bunch on Para-Ordnance mags.

Something to know, is that any of this, including slightly riding the slide release, can cause a bigger problem in wearing out the engagement surfaces on the slide release and in the notch it catches on, on the slide. It can round the tips off in barely engaging, leading to a situation where it's harder for them to engage with each other, so it's something you want to catch quick, diagnose, and fix.

I haven't looked for similar problems reported online, but I might look today.

I don't think it's me, but I could be wrong. Each of these magazines is brand new and I've tested them while shooting, and without ammo. The slide never locks in the open position on this (and the two prior mags). I've even switched up the magazines while shooting to see if the same one created the same problem. Yesterday I shot 8 different magazines and the new one kept having the same problem.

Staccato replied within a couple of hours to my email complaint and they are sending another new magazine. Other than some questions about wear and tear possibilities the first time, they didn't ask any questions this time, and they didn't want the old magazines back - which makes me wonder.

Apart from my own post on Reddit in April, I found the following that sound similar:

• https://www.reddit.com/r/2011/comments/14hhelz/staccato_cs_magazines_fail_to_lock_back_after
  - pre 2024 version
• https://www.reddit.com/r/2011/comments/1fc4ofw/new_cs_mags
  (16 round mags)

These seem pretty limited, as I would suspect lots more forums would include posts if this issue were widespread. I guess I just have bad luck.

I'd consider that good news, if annoying, knowing it's a mag issue. That helps a lot with diagnostics. Also, you now have some free range mags, as long as they're clearly marked.

This will come with a bit more debatablility to it, but the more training you have on the tactical side of things, the less it matters. I still want mine going to full lock-back. But, guys at the highest end of the gunfighting spectrum will go their entire careers without running a gun dry in a live gunfight - dudes with more gunfights than most guys have range days. If the volume of shooting is that high, there's usually a time and place where you can/should swap out to a fresh mag, or you just make it happen. In some circles, running a gun dry in an actual gunfight is considered right at the edge of incompetence, or less likely, a situation that is so far beyond f'd as to be Hollywood unrealistic. If you're shooting a doublestack gun, there just aren't a lot of reality-based situations where a gun will get run that dry, especially in the civilian context. Can that happen because of legit need? Certainly. And again, I want my mags working properly and locking back if dry. This isn't to say nobody should care about whether their mags lock back. They should. Everything above is just being provided as a little food for thought and context for discernment and judgment, and to note that those mags still have utility.

Well said. The chance that I'm ever in a gunfight is pretty low, and the likelihood of the not locking back making a difference is even less within a gunfight. But it's a bit annoying. First world problem.
