You mean the one I didn't read in the manual..........? 124 grain. That's what happens when one makes assumptions, I figured standard 115 grain would work fine........ Obviously I was mistaken.What was the original 9mm specification load?
Ejection issues with my new SAR9

You aren't the first, you won't be the last. At least you went out and shot it some and found that out, instead of right after hearing that "bump in the night".
Other than wheel guns the SAR9 was my first "modern" semi-auto. Prior to that all my sidearms were old soviet bloc milsurp, you could stick a pebble in the chamber with a couple of caps and it would send the pebble down range........ Yeah, a bit of hyperbole but not far from the truth.

Good fer' you.

I’d still be ordering new Wolff springs. I had a similar issue, magazine springs, failing in new Browning mags. While they’re temporarily fine after stretching a bit, new springs are inbound for an ideal solution rather than a workaround. Far more critical in a carry/SD pistol.

Completely different issues.
Your mag springs, I'm assuming were too weak. They weren't going to improve function over time, only get worse. You needed to replace them.
The OP's problem is the springs in his gun are too strong for cheap, underpowered, range ammo. He has a gun with a recoil spring designed for use with defensive ammo. His springs will eventually work with cheap underpowered ammo, but the gun from the factory works with appropriately powered defensive ammo.
After 5,000 - 10,000 rounds his recoil spring assembly will be the equivalent of your mag springs. That's when he'll need to replace it.

Unless he doesn’t care to spend $1/round on defensive ammo. I could easily order some 20 lb recoil springs for my 1911s if I was looking to stop function on them, but the right spring, in every application, is what I was stressing, NOT waiting on an over-sprung pistol to work things out.

All he has to do, and what he's done, is buy cheap 124gr ammo instead of cheap 115gr ammo.

^ There's nothing in the SAR owner's manual that specifies a bullet weight of 124grs.
As printed in their manual..... "Use only NEW quality factory ammunition."
If Sarsilmaz intends to export their guns into the US, they should ensure that factory SAAMI spec'd ammo functions reliably (rather than recommending NATO ammo which runs at higher pressures).

Forever? No.Got it. The solution is to limit ammo selection rather than replace a spring.
Buy two boxes of 124gr ball ammo and shoot it through your new gun with new springs. Then shoot whatever ammo you want.
I'm surprised folks are still debating this. This issue comes up nearly once a week. Nearly 100% of the folks with this issue switch to 124gr or 147gr weight ammo if choosing cheap training ammo, and the issue is fixed within about 100 rounds. After those 100 rounds folks then have success with any weight ammo they want, including the weakest 115gr stuff.
It's not specifically a SAR9 issue, it happens with Glock's, HK's, 9mm 1911's, and many other guns. There was a guy just the other day that had the same problem and same solution on 1911Forum with his Wilson EDC9. He had cycling problems with 115gr ammo and then ran two boxes of 124gr ammo through his gun and now it runs perfectly with the same 115gr stuff that wasn't working before. It is a problem with cheap 115gr training ammo that is typically underpowered, and I suspect is even more underpowered in the "Corona Virus" era when economy ammo is getting pushed out the door with less and less quality control.

Current price of “cheap” 124gr ammo: $60. Replacement recoil spring: $9. Having a high quality, correct weight spring instead of an overweight one you hope will weaken quickly: priceless.
Right is right, half way is not that.

Unfortunately Wolff doesn't carry any springs for any SARs yet.

But they are available elsewhere including from SAR FOR FREE
Okay, I'll check though it mostly out of curiosity.
Put on some work gloves and hand rack it a couple of hundred times.
That will break it in without wasting expensive/scares ammo.
That's what I would do...

By the way I read that the Glock 17 guide rod & spring setup fits the SAR9.
A couple of SAR 9 break in recommendations I read online was simply to leave the slide locked back for a period of time and that would do the trick also.
BTW, don't know where you're getting your 124 grain from but I paid $17 for a box of 50, STV Golden Bee ammo. Czech made ammo.

Springs weaken by cyclical count. If it takes a set by being compressed once for say a week, then it isn’t a very good spring. Consider my case where several hundred rounds of 5.56 is stored in magazines at the ready for years.
Just shopping locally (and not buying, I reload). Either way it’s not $9 anymore and the spring ought to be replaced imo. I wish you luck with your new pistol.
Thanks for your advice but there are other schools of thought on this matter, maybe both are correct in their own way.........
Jocko at Kahr Talk recommended manually cycling the slide "numerous" times as part of breaking it in. When I purchased my Kahr CM9, I manually cycled the slide 500 times, probably more than Jocko was thinking, but I never had a problem with the gun. I freak out if I have a malfunction with a pistol that I am going to use for defense.

The CW9 I purchase for my dad ran fine from day one as did my K9 despite the warnings online. If they hadn’t, I would have replaced springs immediately.
As my loads have evolved for specific 1911s I own their spring rates have changed as well. The specific spring used for any given pistol is an engineering decision but in the case of the OP it’s wrong. The proof lies in the failures and that SAR is now shipping them with a lighter spring.

Well, what I posted is not something I "read online" but something I have done, often, and have had great success doing it.
Hand racking has become something I do, before shooting, any new slab-sided/brass chucking/scrap-o-matic I acquire, especially small guns.
Just a suggestion though, something you can do or not, no difference to me.
jmo,
I'm doing a combination of "all the above" including checking with SAR USA concerning lower powered recoil springs. Since it's the weekend I'm sure I won't hear from them for a couple of days.
