Issue with my new P320 X5 Legion, Help

Recommended Posts

 
 
Before shooting my P320 Legion the first time I cleaned the internals.
During my 200 rounds of shooting on a few occasions the empty shell would get jammed in the retractor, and on some last empty magazine rounds the slide did not open.
Any help would be appreciated, thank you in advance.

1st.. holy shit.. proofread what you type and take the time to type something coherent, I'm having to guess what you actually intended out of your clearly gun related but still approaching word salad in the back half post there. I'm glad to help, but there's only so much to be done without a clear description of the problem.  

So my best guess on translating your post into questions. 

1a) You are having issues with failure to eject where some spent cases are not ejecting and remaining hooked on the extractor causing a jam when it tries to feed the next round. 

or possibly 

1b)You are loading up. pulling the trigger, get a bang and the gun seems to cycle, but next time you get a click, clear the round and find a fired shell with no bang to go with it. SO you are getting failure to eject, failure to feed, and reinsertion of the spent round. 

2) you are having issues with the slide not staying open on an empty magazine. 

 

Both versions of #1 can be caused by a bad ejector. On 320 based guns, make sure the ejector has not been bent up or otherwise damaged. It's this doohickey circled in red in the picture. If yours doesn't look like that in some way, you probably have a problem that is going to need to involve Sig CS.

Both versions of #1 and #2 can be caused by the gun short stroking. Possible causes of that: 

a) making contact with the slide with your thumb or any other part of your hand while shooting and thus creating drag on the slide. 

b) Failure to properly lube the gun. You said you cleaned it, you didn't say if you lubed it, but especially with the tighter lockup of the x-fives, lube matters. 

c) Light loads and strong springs. If you are shooting cheap ass 115gr bulk plinking ammo, you should probably switch to the lighter of the two springs included with the gun. 

d) A variation on a above. Your making contact with the slide release while operating the gun. The slide release mechanism would then in turn be creating drag on the slide causing short stroking if/when you push it up, and if you are pushing down, it will prevent it holding the slide open after the last round. 

e) You have somehow created mechanical interference in the travel of the slide that is not permitting full travel. Like installing both recoil springs at once. I don't think this is possible and still having the gun work at all, but hey there are some impressive members of team push it harder out there. But in general check for anything mechanical that may be interfering with the full travel of the slide. 

f) The frames are injection molded plastic. Check that there isn't some huge chunk of flashing or piece of sprue left in place by QC people in the dust cover area dragging on the slide in use (or anywhere else, but in general with polymer guns, that's the most likely spot for something like that). 

g) If you are teacupping the gun and pushing up on the mag... fucking stop that. It's horrible form and can cause jams by pushing the magazine in and causing too much drag on the slide from the top round, causingslide lock prior to the last round being fired, etc. Depending on the gun in question.  It's also possible to damage the ejector on the 320 by shoving the mag up into the gun too hard under certain circumstances. (i.e. slamming the mag in hard on a 21 round mag with aftermarket baseplates that don't prevent over insertion, but hey anything is possible if you are on team push it harder). 

If you don't know what teacupping is,  here's a helpful graphic: teacup.jpg.4e8b8be30583af102467a9a1e51d0ce8.jpg

Hold the gun tighter.  Try what feels to you like a "death grip" until you start shaking and then back off just until the point of the shakes going away.

All of what raz-o said is also possible, but if you're new enough to call the extractor the retractor then you probably don't have a proper grip on the gun and that very often causes what you're describing.  I doubt anything is wrong with the gun itself.

Thank you for the info, and yes pretty new too owning my own gun.

What kind of ammo are you using?

A friend at my club had similar issues with his brand new pistol but he was running handloads through it, so that was the culprit.

Some manufacturers recommend running a few boxes of 147gr ammo through the gun first to break things in, but I'm not sure about Sig...

I will +1 what pewpew plates. Said. Limp wristing can lead to poor ejection. I will add to it that you can have a death grip and still have noodle arms. So apply a little muscle up to the shoulders.

Using Remington 115 gr, but will try your suggestion. 

Thanks

I’ve got 4K + of federal 124 through my 320. Not one issue.

label your mags but also make sure you aren’t riding the slide release.

Could be ammo, other day at range used some PMC bronze 115 grain in my Beretta 92 and PX4 and both would jam and not load every 3rd or 4th round, worse with the PX4 than 92, Switched to American eagle 115 grain not one issue with either.

Going to try some different ammo this weekend, thanks.

Thanks a million, I will try these tips, and try the lighter spring.

Happy New Year

Thank you all for the help, and suggestions.

Just came back from range with shooting 200 rounds with no issues.

I changed the spring out, and lubed again with using the same ammo plus another brand, and the same 5 magazines I have.

I think the back sight guide needs to be adjusted some tho.

Peace out, Happy New Year!

    • Personally, I don't use any multiple units cleaning kit - you shold do your own research to know what works for you. When it comes to cleaning, Rem oil is about all I use. Tried Hoppe's for a but, which is good for really caked on stuff, but I clean my guns every time I shoot them, and remoil does just fine cleaning and lubricating. Tho I recently got some renaissance wax for rust protection on some of my blued guns. So far so good, shines them up nicely too
    • Waited 5.5 months for my 1st fid and 2 p2p's. Got them last Wednesday. So hard to find guns locally. I googled my ass off for 24 hours straight and constantly emailing out of state dealers. Got my 1st sig p229 elite dark delivered at dealer Saturday at noon .was told not to come in till 3pm due to overcrowding in-store. Filed nics paper and my jaw dropped when I found out it was not instant. I told my baby I would not leave her stranded. There was 1584 in que Saturday and they were working on Wednesday work. By close of business Saturday they started Thursday. Sunday they were still on Thursday w 1600 in que. Woke up Monday their still on Thursday with 1617 in que. Now waiting to see what Tuesday says .hoping Tuesday by end of day says working on Saturday. That is me wishing. More like working on Saturdays Wednesday and since .one was 330pm Saturday I will get a call Thursday. After reading on another forum. I had no clue the njsp nics was different background check than the initial njsp background check that happened right after fingerprints. That would suck to be approved for p2p and fid and spend 1200 bucks to have come this far to get denied from njsp nics. From all my hours of reading. Trust me, 100s of hours. How would the njsp nics show anything that would get me denied that the initial njsp background check didn't show ??? What really Yanks my chain. Is I paid for an expungement prior to covid and got a letter from njsp i have a clean slate but local PD still saw all of it. They said perhaps they didn't get to it due to covid but I still past the sniff test. Nothing on my record was ever charged all dismissed.   Good luck to all
    • That sucks.  I was just looking at joining them.  What happened?
    • WTF Mossberg 500 vent rib barrel 24" or 26" w/ choke tubes Black color. No rust, no shooting issue. Minor scratches are ok.
    • Hello Like the title says looking to trade or sell my Squid Industries Mako Balisong. This is the inked version so the "blade" is black. Its actually a bottle opener/trainer so its exempt from any knife laws. Fun to play around with in between opening beers without getting cut. Its in great condition 9/10, only dropped a couple of times. Looking to trade for any E series surefire complete or parts (will add if need be) or will sell for approximately $75 Feel free to message with any offers or questions. Thanks!
