I’d return it for warranty work, that’s what the warranty is for.

 

The XC is typically a great gun,I’ve had zero problems with mine, Im thinking you just got an idiot on the phone from the warranty department,usually Staccato has a great service policy and great customer service,overall the XC is a great pistol

 

Staccato support is really good. If you already got an RMA, then send it in for service. For what it's worth, I've sent in just about every new gun I have for service - just my luck. They usually come back fixed, but with extractor I had to send mine back a few times (another brand). I can appreciate your frustration... but now let this headache be for the people that built it.

 

Sorry to hear that you’re having issues with the XC.
I’ve had mine for only a couple of months and I freaking love it.

Send it in and get it fixed. Shoot the **** out of it.

 

Right thumb on the thumb safety is how most folks end up slowing down the slide with it. That’s how I did it when I first started shooting 9mm 1911s 🤣. XC has a very light slide and light springs so it’s very easy to do this. Take your thumb off the safety for few mags - if the issue goes away it’s you squeezing your hand.

 

Several times, when the slide actually did lock back, there would be the final spent shell casing, just sitting on top of the magazine.

look at my ejection pattern, there's a bunch at my feet in 12, 3, & 6 oclock vicinity, and then theres a rainbow of all different distances on the ground heading out in a normal ejection point.

This is an extractor issue, which seems you have already resolved.

If I have a strong form grip, it wont lock back. If i shoot with 1 hand , or i allow limp wristing, it locks back. My support thumb is NOT interfering with anything at all. Thumb on my right hand is on the thumb safety.

Highly suggest sending it back and having Staccato address the issue; but if you're going to tackle this on your own, I'd start by testing each mag - load a single dummy round or snap cap, then cycle the slide till empty and confirm the slide locks back with full engagement of the slidestop into it's recess in the slide. If you don't get lockback when hand cycling with the majority of the mags, then the issue is likely the slidestop nub that interacts with the magazine follower; if it's consistently with certain mags and not others, then you might have some defective mags.

If during hand cycling everything functions as it should, then either the slide is outrunning the magazine during firing (cycling before the follower has a chance to push the slidestop up) or your grip is the problem (somehow interacting with the slide stop and keeping it from rotating up).

Did you happen to change the recoil spring or shove a shock-buff in there? The slide might also not be cycling through its full length of travel.

I also suggest focusing most of your testing around the 17 round magazines. Any issue and malfunctions I've had with the Staccatos I've owned have revolved around the 20-rounders.

 

This sounds eerily similar to my first XC which I sold before getting it fully resolved. My second XC has been golden.
Like others have suggested just send it in and let them deal with it.

 

The only problem I've had with my XC is not being able to shoot it all day, every day. Mine has been lights out. Staccato has a great warranty. Send it in and they'll get you squared away so you can enjoy that beast!

 

Ammo - Winchester Q4318 124gr fmj pretty much a +P rated ammo

Try something else, I've had issues with WWB.

 

Also agree here. Not sure why you think this stuff is +P. I use Fiocchi and S&B out of mine. 12-1300 fps and a real copper jacket not plated.

 

Most know I'm not a fan of S?!?!?!?!?!O because of thing like this.
In the STI days they would have fixed it w/o any problems etc eetc

Couple of thoughts
Ammo that is nato pressure or more to run the comp effectively for a couple thousand rounds
Your pistol may be slightly tighter than most etc
Try an 8 lbs recoil spring and see if it helps

Slide off and look at interface of magazine follower and slide stop
Measure lobe on Slide Stop , make sure it's a 9mm SS

 

I’d be heartbroken, let them fix it, you’ve already paid for the warranty, send it in.

 

Just send it in.

 

They literally sent you the label for the warranty return to get it running right, and instead of sending the gun in, you come to the internet and complain. What more do you expect them to do?

Yes, it would be nice if everything worked the first time, right out of the box, but this is real life and sometimes it doesn't. That is why buying from companies with great customer service matters. But the best customer service in the world doesn't do you any good if you then proceed to not use it.

This is why I'll happily pay $500 over the 'other guys'.

The customer service and multiple interactions and warranty work I've had with Staccato over the last 5 years has been flawless.

 

I'm usually the poor schmuck who gets the rare lemon from guns with reps for reliability. I generally don't gripe unless it's an issue obvious as soon as you look at it, or if I send it back and it returns with issues. I know it's BS and a PITA to send back a brand new gun to get it to actually run, but WTH are you doing wasting thousands of rounds of ammo and calling the dealer every day? Send it back!

 

Take a deep breath and send the gun in for warranty work.

 

Definitely send it back for warranty work. The rep must have been new, most of the reps ive encounters are super nice and extremely helpful. Especially when it came to my XC more than others.

 

This feels like a sig bot post stirring S up to deflect from their uncommanded pews 🤣. If I am wrong, 1000 pardons....

 

Hello,

I have a 19’ P that refuses to run reliably with Winchester Ammo. That and S&B 115. Ran the S&B 124’s fine. She still hated the Winchester 124’s. Its in really good condition and was not fired a lot at all. She hated magtech too.
It runs everything else fine 100%. I called Staccato and they recommended not using Winchester and Magtech ammo. Ive run magtech and winchester through an XL, Heritage P, 2 other 19’ P’s, and a CS flawlessly, sometimes certain pistols are finicky. Id send it back if I were you! They usually work pretty quick!

 

You put 1700 rounds down range have that many issues?

I would have sent it in after 3-4 hundred.
