Help Diagnose My Pistol's Malfunction

I have a P320 XCarry Legion 9mm with a threaded barrel. It's a new gun and well oiled. I run an Advanced Armament Element 9mm can on it with a booster. I have tried running several kinds of ammo through it but it all has the same results and 147 subsonic is all I want to run in it. For every shot it loads the next round in the chamber but it doesn't cock the gun so when you pull the trigger nothing happens. You then manually cycle the slide and a loaded round comes out of the chamber. Sig said they won't give advice other than to buy one of their cans. It ran fine on a Beretta 92. I tried to buy a lighter recoil spring but Wolff doesnt sell them and neither does Sig.

What ammo brand? Is the can the Illusion (Element comes up rimfire)?. The Beretta has a longer barrel than the Sig so that helps the Beretta cycle.

I suggest you contact Advanced Armament and see what they suggest.

If you have a captured recoil assembly replace it with a 1911 style guide rod and a 12 lb spring. You might want to try two or three other springs in different weight ratings to tune it to your liking.

The striker is reset within the first 1/2 inch or so of the slide travel, well before the expended shell is ejected and the next round loaded. That makes it unlikely that your pistol "doesn't cock the gun" if a new round is being loaded. Two possibilities occur to me. First, since you indicate the gun is "well oiled" you may have actually over-oiled it and allowed some oil to enter the striker chamber. Second, the gun may not be fully returning to battery after loading a round. This, too, could be attributed to too much lubricant since you're dealing with a Sig. If either of these is the case you can likely clear the problem with a thorough cleaning, well beyond the recommended cleaning procedure since you might need to fully clean the striker channel.

I guess AAC is back up and running. Last time I checked Remington had shut them down. I'll call. The element came before the Illusion or Tyrant. I've been doing silencers for a long time now. Back when Cara and Kevin answered the phone there themselves. I'll do the thorough cleaning too. Thanks. I'll report back. What happens. I did find a company that sold a spring kit for the gun but it came with 12,14,15 pound springs and Sig told me the gun came with 12-14 pound spring so it seems the three spring kit only has one that is diffenert than factory and its going the wrong direction in stiffness. I wasn't aware you could put a 1911 in an P320

"I have tried running several kinds of ammo through it but it all has the same results and 147 subsonic is all I want to run in it." What does "several kinds of ammo" mean? I hope that doesn't mean Bubba's reloads from the gun show or remanufactured ammo from the same place or an online vendor. Does the gun run fine with that ammo w/o the can? Have you tried 147-gr. subsonic loadings from Black Hills, Hornady, Federal. Norma, CCI/Speer, W-W, and Remington? I would lay in a few boxes of each, then clean the the firing pin channel, leaving it, the firing pin, and spring dry. If possible, get a new factory FP and recoil spring. Clean the rest of the pistola thoroughly, dry, then lube with Slip2000 EWL. It's possible that you will need to an aftermarket guide rod and spring kit to tune the gun, since you are hanging a weight on the end to the barrel and trying to run wimpy loads through it... If yu find a brand that works, then buy a few cases of it.

I have a compensater issue post on here you should go through, it's the same issue. There are no spring kits for the carry size slides. To fix my problem I made a kit from a 1911 commander guide rod and 1911 springs of different weights cut down. This is about your only option.

I think I heard somewhere that AC is working on a spring kit, but not sure when it will be available.

That's good ammo. Does the pistola run that ammo w/o the can?

Although I have very little experience with suppressors, I have a lot of experience with compensators. Compensators will delay the unlock, I believe that some suppressors will do the same, but that usually results in FTE or FTF. But does not explain the firing pin issue. My FNX45 will not eject Factory range ammo with the compensator on it, only +P, Super or my hand loads. I've seen on other forums the same complaint with certain cans.

I will see if I can find that thread, sounds like information I could use. While I'm here what is your best recommendation on lubrication for a P229 DA/SA? I've used Remoil with Teflon for many years, but it seems Sig Sauer owners tend to use something a bit heavier.

I've used CLP since it was introduced to me years ago in the military. The only exception is I use Lucas gun grease on the barrel hood, everything else gets CLP.

If it's extracting the spent case and loading the next round the striker should be cocked. If you are not feeling the striker being released, could the disconnector be at fault?

I do believe that people have had some success in your situation by using the DPM system. There are a number of threads here that exhibit similar symptoms with the compact/carry and suppressors and compensators.

He nailed it. For the carry, pretty sure this is the only real option for you. Go with the lightest spring and should be good. As its a new gun, make sure you break it in real good as well, run it without the can for a bit. Just because its oiled up doesn't mean it doesn't need to still be broken in.

Does the slide go all the way forward? Legions can be tight fitting, and need a couple hundred rounds through to loosen it up, before using a can, or compensator.
