Stuey Posted November 10, 2021 Share Posted November 10, 2021 Looks like a fired out of battery. Double charge would have more damage to upper part of the frame and not middle. Link to comment Share on other sites More sharing options...

Ssanders224 Posted November 10, 2021 Share Posted November 10, 2021 Neither. Google around for “Sig 320 unsupported chamber”. There’s info on this forum and others. There’s many failures just like yours. Link to comment Share on other sites More sharing options...
jaep1911 Posted November 10, 2021 Share Posted November 10, 2021 Dang, hope you were alright. These incidents scare the crap outta me. When I dry fire and reload with a mag fully loaded with 147 gr dummy rounds, the slide sometimes moves out of battery slightly (1/16 ~ 1/8”). When I press the trigger, the slide moves forward and I can feel it. I’m using an original X five slide ass’y with a 13 lb recoil spring. What recoil spring are you using?

The one above looks like a double charge though. That primer pocket is gone! Edited November 10, 2021 by dansedgli Link to comment Share on other sites More sharing options...

But the same failure is way to common. Link to comment Share on other sites More sharing options...
38super Posted November 10, 2021 Share Posted November 10, 2021 Rupture around extractor groove, brass formed to feed ramp, missing primer, case head flush with barrel tab. Double charge. Link to comment Share on other sites More sharing options...

Double charge. Eh. Possible. Not necessarily. I’d guess it’s just another failure similar to these (all 320s). Link to comment Share on other sites More sharing options...
dansedgli Posted November 10, 2021 Share Posted November 10, 2021 (edited) Mine only ever blew out the sides. The bottom of the case was ok. Worst barrels ever. In 10 years time people will be talking about sig face or sig bulge instead of the glock bulge. Extractors will also be sold in bags of 10.

Hooked Posted November 12, 2021 Share Posted November 12, 2021 Has anyone heard of these issues happening on the X5 Legions? We’ve seen 5 or 6 X5s with blown out grip modules around here, but these were all earlier gen guns. Link to comment Share on other sites More sharing options...

Braxton1 Posted November 22, 2021 Share Posted November 22, 2021 I recognize two of the kaBooms in Steven's post. Those came across my bench from a GM shooter who is a VERY experienced reloader using a S1050. I'll give you this: The case heads all look like you'd expect from an over-pressure round, but I am having a tough time believing that 320 shooters have suddenly started having a string of double-charges coming out of their presses. In over 35 years of loading for USPSA and IDPA, I have never double-charged one and have only squibbed two. (KNOCK ON WOOD.) And I am a fast loader. I am cranking that handle at as fast of a pace as I can maintain, not stopping on every stroke to peer into the charged case. Link to comment Share on other sites More sharing options...

Exactly. 320 owners didn't just suddenly start buying and loading bad ammo. The oddly short chambers, and their (admitted) ability to fire at least somewhat OOB is what is causing many of these occurrences IMO. Link to comment Share on other sites More sharing options...
dansedgli Posted November 23, 2021 Share Posted November 23, 2021 Before I bought my first P320x5 I loaded 8000 rounds in one batch on an autodriven 1050. I shot 3000 of these through CZ's, glocks and 1911's with no problems. Within 50 rounds on my new to me X5 with a silver barrel I noticed bulged cases, I continued shooting and lost my extractor when a case finally ruptured. I thought the barrel was faulty beause it had a huge lack of chamber support compared to my other guns. I posted on here about it so I bought another new P320 x5 with a black barrel while I tried to track down a new barrel for the first one. I tried to get warranty support with no luck. Less than 1 full mag in with the new gun I had bulged cases again. Back to shooting CZ's, glocks and 19/2011's and that same batch of ammo had zero problems. The x5's don't have the right chamber support to use faster powders or marginal quality cases. If I swapped out powder it was fine, if I sorted my brass by headstamp it was fine. The cases that did not work in the x5 are fine with 9 major in my open gun if that is any indication. Link to comment Share on other sites More sharing options...

Nuncles Posted November 23, 2021 Share Posted November 23, 2021 Can anyone confirm if aftermarket barrels offer a more supported chamber? Faxon or Barsto barrels seem to be the ones I see available right now. Link to comment Share on other sites More sharing options...
