If you like fun .22’s you should definitely buy the Taurus, it’s cheap and a great gun. Although there’s plenty of TX22 owners and previous TX22 owners that claim all the same problems you hear about the P322. I’ve seen a few instances of people swearing off all Taurus products forever because of their TX22 issues. I have both guns and have had some issues with both that I got resolved. Sig customer service is a lot better than Taurus if you do have an issue though. It amuses me when people have a grievance and go all sour grapes about it. Some guns have issues; give Sig a chance to make it work and get a TX22 too.

understood. This is just super frustrating. I’m not swearing off Sig…this is my eighth Sig. I’ve been through the P365 and P320 issues.

CS called, RMA coming.

I have one that was doing the same thing ask a friend about it and he said it was probably a Weak magazine Spring told me to go buy a New one never had no more problem with it. I also bought a 25 round sig magazine for it as well. It works perfect .I decided I would take the magazines apart And compared it with the newer One that I bought . And found that Both of the Springs was shorter than the newer one. Understand that I had probably shot Fewer than 300 round through this thing. Just waiting for something else to mess up with .

I didn’t consider weak mag springs. There might be something to that. I bought all my mags around the same time, so they probably all have similar springs. Hmm. 🤨

I have about 550 rounds thru my P322, I have had the best luck with CCI “clean 22” (has the “pink ribbon” on the plastic bottle, bought at the range at SIG. My bucket of bullets are useless at the range with this gun. I also didn’t have any issues using their target ammo. It hasn’t been locking back consistently, I do need to clean the gun…

That is what I thought as well, that perhaps the rounds are too weak. I used three different popular brands of ammo, had the same results with all of them.

The reason why I mentioned dry firing wasn't because it would affect the slide. I mentioned it because when the slide does not lock back after the last round, I continue to pull the trigger. The rim fire firing pin hitting the edge of the barrel often, will ultimately result in damage. That is my concern. I believe that at some point I'll figure it out. The pistol is not my EDC, so I'm not overly concern. If the pistol gets damaged, I'll just send back to Sig.

Another gentleman mentioned, the last round loading as the spent shell is being ejected, resulting in the slide closing before it has a chance to engage the follower. I don't know if that particular explanation is viable. I guess its not inconceivable.

I do appreciate and thank you for your replies.

I use CCI Mimi-Mag copper plated round nose. I have no problem with that issue.

Same for me.

I got my P322 back from Sig and repair notes say “adjust slide catch lever. Passed all function test. Ammunition used: CCI Clean”.

At the range, it operated correctly for the first 200ish rounds, then the slide stopped locking back after last round. At least the slide catch is holding the slide open when manually operated. It used to slam shut if I looked at it wrong. Except for the lever on the right side of the gun…it will not lock the slide back ever. Weird.
I also sent my mags with the gun asking them to check spring tension. No notes on that.

I’m not looking forward to sending the gun back again, but I will if this doesn’t resolve on its own. I’m going to clean it and hit the range shortly, running another 8 mags worth through it and see if I’m irritated enough to call Sig again.

As far as ammo goes, it will feed and fire pretty much anything, if the mags are loaded correctly. It seems only CCI Minimags will load into the mags correctly, so that’s all I’m using.

CCI Clean only has a muzzle velocity of 1070fps..CCI mini mag 1235fps..Let us know how it goes..

Maybe after they're done releasing all the different color variants they'll have time to re-tune and release replacement parts

It’s likely due to low pressure from your ammo or the recoil spring being too heavy — meaning you need to further break it in. I also am very lucky and got a non-lemon P322. Actually, I don’t think it’s luck. I think Sig simply fixed and tweaked things as they always do. No fouling, no jamming, etc etc.

But I also wonder if my positive experience is because I exclusively shoot my P322 suppressed. I’m at 9K rounds and I think I’ve only ever shot 5 unsuppressed. And in total, I have had only one FTR and a single FTE — solely because I hadn’t cleaned the handgun in 3K rounds from its heavy carbon buildup. This was stellar, considering my Ruger MKIV Tactical begins having FTE’s after just 500 rounds, suppressed.

My theory is that extra back pressure from the suppressor aids in reliably cycling the slide and giving it a little extra “oompf” to the slide. And because of this, I almost never have issues with the slide locking back. I can think of many two times where it didn’t lock back, on the last round. That said, the slide loves to engage after putting a fresh mag in. But it’s a non-issue for me. My HK VP9, P30SK and P30L all do the same lol.

So yeah! Try hotter rounds. Or buy a suppressor. I recommend the latter, the P322 Is a phenomenal .22LR. suppressor host. Especially under NODs. I threw an IR laser on mine for that exact reason.

Pretty sure I need to drop mine off at SIG. can’t EMS gone more break in than another 400 rounds through mine, I’m on my 3rd bottle of bullets. My wife loves to shoot it. The slide lock is also very touchy, doesn’t work on type right side, but does on left. I am left handed, but always set it down so that it’s more visible (so flip to lay on right side) when you go to pick it up, that it’s empty. When I do that, 75% of the time it snaps the slide closed, with or without a clip.

Besides the 50 rounds I had shown above I have used the same ammo they require you to use if you rent a P322 at Sig Experience Store. It’s CCi “clean 22” 40 grain 1235 fps .22lr ammo.

Mini mags have been working well. The mags seem to like loading them better than other ammo. After Sig adjusted the slide catch, the slide doesn’t lock back after last round again and the lever on right side of gun is useless. I guess it’s gonna go back again. 🫤

At about 800 rounds of CCI Mini-mag copper plated round nose, I started having issues with the slide not locking back. Cleaned the mags, still had lock back issues with out of three mags. Changed ammo to standard velocity (Armscor 40 grain round nose). Lock back issue reduced to one out of six mags. Note: I always thoroughly clean my pistol after each range visit of 60 rounds. Recently, I noted some burned powder residue inside the slide release levers on both sides of the pistol. Took my can of Office Depot Cleaning Duster (Air) and blew out all the areas around the slide releases (Inside and Out). Took my spot oiler of Lucas Extreme Duty Gun Oil and put 2-3 drops of oil in the top slot over each slide release lever and 2-3 drops of oil under each slot of each slide lever. Took my can of Office Depot Cleaning Duster (Air) and blew the oil into the slide lock levers. Cycled the slides. Now, after 240 rounds at the range, no more slide lock back issues with all of my three magazines and Armscor standard velocity ammo. Another Note: I always use the chamber flag. I only release the trigger hammer with the chamber flag installed...no light strikes. These techniques seem to work 100% for me and my P322 is working great.

Got it back from SIG, it was gone for 7 days total. They fixed the slide lock issue. Slide locks back everytime. Hope it stays that way, over 1200 rounds through it. Great pistol!

Hey everyone! New P322 owner with the exact same symptoms as the OP. Very 80 rounds of CCI mini mags locked back fine. Second trip today 120 rounds same ammo, first mag locked second did not third did but slammed close soon as I put the next mag in. Manual open with empty mag locks fine.

I cleaned the gun really well and got the loop and head lamp out to see if I could figure out how the catch works (new to guns but was a school trained auto tech for 12 year in my first career) Anyway, once I realized the follow pin in the mag was what pushes the locking lever into place, I cleaned and lubed the mags. While investigating with the slide off and empty mag in, when pushing down on the follower in the mag and release it, the lever kind of raised sluggishly. I proceeded to lubricate all pivots on the locking lever and disassembled the mags to clean the carbon from the top and hit the inside, follower, pin and spring with CRC spay silicon then blew everything dry with compressed air before assembly. The push down test of the follower was markedly better with the lever moving fast and smoothly. No idea if this will have any effect on live fire but seems like it might, since it worked fine the first use. Will be a few weeks before I get to try it again. From the looks of things, I assume they just bend the lever up a tad ..

This is where the lock is sitting on mine when locked back manually, just curious to know what it looks like on someone gun that is functioning well or has been "Adjusted by the factory"

 

[Danhikeski]

So the angle (on the “lock” as you call it) was changed when I sent mine in. I couldn’t tell you if it is more severe or less on an angle than before, just know it looked different when I got it back.

bottom line, if it isn’t working correctly, send it in. It should get back to you fairly quickly. I live within 10 miles of where it went and where I bought it (SIG Experience store), and got it back in 7 days. Wish I could have taken it to where it was fixed (even closer to my house!), but that’s another (long) story.

It would be great if another member could post a similar photo of the lock back lever on a gun that works correctly.
That way we can compare both photos.

 

[pelican4544]

Here's my photos of lock back on my Sig 322. It's working correctly.

 

[airscapes]

Not a lot different.. just got off the phone.. printing the shipping label now. They did ask for the Mags..
My luck it will work prefect for them

 

[SW547]

Try this test.
Insert an empty mag in an empty gun.
Pull the slide back and lock the slide manually if it doesn't lock back automatically.
Now position the gun so you can manually pull the slide back just enough to take the pressure off the lock.
With a pen push the follower on the magazine up and down and observe the little bar in the back. Does it move up and down too?

If it doesn't YOU have a DIRTY GUN that's all.

Got mine back today, Adjusted Slide Lock Lever.. Oh so very slightly, will test it out in the coming days.. also got a 25 round mag to try out.
