Weird issues with Sig Sp2022

[kotton]

So I bought a Sig Pro and took it out a few months ago to see how it shoots. I brought along two 50 round boxes of winchester 115 grain 9mm and loaded it up.
Immediately I had issues with every other round jamming, and the every round that ejected only ejected about 6" high 12 o clock from the port and smacked me right in the forehead. This continued for the entire box of 50 rounds, so I went back and broke it down and gave it another good cleaning.

I went back the same day after the cleaning and tried the other box of 50 rounds and had the same results.

So I get back home from the desert and called sig, and they told me to try another 200 rounds of a heavier 124 grain 9mm bullet, to break it in.

Fast forward to this Saturday, I get back out to the range and bring the new ammo along. Instantly I have 0 issues and get through all 200 rounds without a Jam or casing hitting me in the face. This time they ejected at about the 2 o clock position and had a little more force coming out.

So after I was done doing that I decided to try out the leftover 115 grain winchester 9mm that I had, and had 0 issues with it.

Should I consider this issue to be resolved, and chalk it up to the gun just needing to be broken in? Ive heard of guns being picky with a certain brand of ammo, but it just strikes me as odd that shooting a heavier round would fix it to where I could somehow shoot the other brand that was giving me problems at first.

Are you using new 10 round mags? I have a couple Sigs that initially gave me feeding problems with 10 round mags, but they loosened up pretty quickly. Some knowledgeable person may be able to say, but I think those mags may use the same springs as the standard (high) capacity mags, and so are initially really tight.

Also, if it was the Winchester White Box ammo, I have had consistent problems with it in my Sig Pro. Extraction problems, light loads (have had to check twice to be sure I didn't have a squib in the barrel). I now have over 4k rounds through mine, with no problems with Federal, Fiocchi, Independence, Win Nato or range ammo.

So, if it were me, I would give the Sig Pro some more exercise with non-Win ammo. I'm guessing it was an ammo problem, no a problem with the gun.

Had the same problem but more rounds fixed it. Def doesn't like lighter loads/reloads.

I would. The springs are mighty darn stiff when they're new.

When I got mine late last year, I shot a box of 147s first, then 124s, and almost nothing but 115 since of WWB, Federal, Blazer and a few others. That includes around 500 Freedom Munitions reloads. Not a single hiccup.

Since then I managed to get a small supply of 124s that I keep for "breakin" ammo.

Mag springs are a bear too. Was very hard to get that 10th round in even with my Uplula. After a few cycles, they've become easier too (although not cheaper!)

Keep the rails well greased too.

Thats the weird thing though. I have another sp2022 that is 2 years old and I tried using the two 10 round mags I have for it in this new one, and still had jams and ejection issues. I never had to break that older one in either, but I guess it was just luck.

I'll try going back to the range soon and see if I can run a couple hundred 115 grain white boxes through it without issue.

When we purchased our Sig Sp2022 in December of last year, I was concerned about running 115 grain ammo during break-in. I asked the guy at the counter and he said that the regular 115 grain should be fine. 500 rounds of Blazer and not a single issue. I did clean it and lube/oil it up really well before it's maiden voyage too.

So far, about 1100 rounds down range in that pistol and all is well. All of the ammo has been 115 grain. After the initial 500 Blazer, we shot 500 rounds of FMJ reloads and so far 100 rounds of hard cast lead reloads (Bulletman reloads). Only had one failure to go into battery. The cartridge went forward into the chamber, but didn't slide up under the extractor. Weird.

Anyways, no other malfunctions at all. Love this pistol. Just got a really nice kydex holster from KT Tech. Wife is getting set to use this when we go for some training!

The mags are a pain to reload without an UpLula. They are worth their weight in gold! Or, ammo! Just got another mag and paid way too much for it. Ugh...

Hopefully your problems are a thing of the past. Oh, our empties eject at around 4 o'clock or so.

Happy shooting and be safe!

I had similar issues with my sp2022 9mm when I first bought it. I was also using Winchester white box or reloads from the range to break it in. After a few hundred rounds all problems were gone and the thing has run flawless for the last 1000 rounds or so. I read other people having issues with the 2022 break in so I wasn't that surprised or worried about it when it happened to me. I would guess that your gun is fine and probably is officially "broken in".

Just fired my SP2022 today, I got it as part of a trade. I had no issues shooting my own reloaded (previous owner had put about 250 rounds through it) and had good ejection. It will take a little while to get use to such a high bore over grip but is definately gonna be a fun gun
