What ammo are you shooting?
Bullets may be slightly undersize. I had this issue with some bullets that I bought of Gunbroker to reload. Shot ok from an aftermarket barrel with conventional rifling, but not from the stock barrel. Then later figured out the were slightly undersize.
That barrel is barely broken in.
I'd suspect the ammo first.
Or possibly your grip/pull. There's a clock chart that shows common mistakes/errors associated with handgun use based on POI.

I took it that "yaw" meant lateral POI shift.
If by yaw he means it's keyholing then that's different and most certainly related to the ammo if the barrel was fine when he got it (and hasn't been fucked up, which again, would be amazing considering how damn tough a Glock barrel is). There's a reason nobody wants to thread factory Glock barrels.

That looks more like a wonky tear than yawing.
Make sure your target is firm against the backer and shoot a few mags with a new backer.
I get "wonky tears" in the targets when shooting against a beat up backer.
Could be ammo, but Im with Steel head on this one.

hows it grouping?
if its grouping fine, even with the suspect shots, chances are like stated above, its odd tearing....if you notice fliers that are way off, and those are the suspected tumbling rounds, then you might have an issue.
mount some heavy card stock to some carboard and try shooting through that next time.....should give you some nice clean holes.

LOL.................no
The recoil spring and its guide rod have fuck all to do with accuracy.
Looking at the picture of the wonky hit, it does look like the bullet when in sideways based on the appearance of the grease ring.
How many rounds since the last cleaning? When did you start using this particular 165 gr ammo? What other ammo have you tried?
It was a secure target with no backer. FBI bowling ball looking target.
I have not used that particular ammo recently, mainly because we are shooting steel. I will admit it needs a cleaning. I am going to clean and try different ammo.
Thanks

If the spring is worn or too light it certainly can. Won't make them tumble though
My experience tuning guns for optimal recoil characteristics for USPSA says otherwise.
The opposite experience of thousands of USPSA competitors, which combined probably fire more handgun ammunition in a year than the rest of the pistol-owners of this country do in a lifetime, does.
Agreed, I think its a ventilation blown target causing this. Seen similar many times with targets shot without backers or good clips.
Also, I loathe the notion of a wheel of explanations for pistol shooting, usually clown shoes explanation for poor instructors. Just my opinion, usually a combination of ailments cause issues. Most of what I learned was by watching the shooter and not just the target input.

That isn't the experience of thousands of shooters though. Too light of a spring or a worn spring will cause inconsistent lockup. Here is one thread on Enos. There are many others like it
2011 open - light recoil springs and accuracy
Thought I would share an interesting troubleshooting exercise with a very definitive solution. First the baseline. Using my standard 9 major loads in a brand new gun (9 major open from Atlas), I put 5 rounds in a ragged hole under 1" diameter while sighting in at 50 yards. Nice! Fast forward 1500...

Anyone can take things way too far. That's how learning occurred.
I'm running a P-09 that has just over 14000 rounds with a 13 lb recoil spring that has right over 2000 rounds with stellar accuracy. The OEM recoil spring is 20 lbs.
There is no way a recoil spring dies after 1000 rounds.
What most of you think is a high round count for a pistol.... isn't.
You arent the only person on this forum to shoot pistols competitively. I've put tens of thousands of rounds down range in various USPSA, 3 gun, and Steel Challenge matches. I completely agree 1000 rounds won't kill a good spring. But there is no way every recoil spring gets QC'd and flaws and defects happen. Read the thread I linked you to. The guys spring died in 1500 rounds.
The point is that a weak spring can cause inconsistent lockup and can effect accuracy. While it might not be fuckall, it's certainly fucksome.

Thats why I was asking... it wasn't clear to my tiny brain
Looks more like the target is loose, not tight against the backer.
I know exactly what the problem is. The problem is that it’s a Glock. Buy a Sig and this shit won’t happen 
Im gonna guess @trauma1 is a nurse, NP, PA, or MD.
Thats the problem. Those fruitcakes from the medical world trying to shoot.
Or its just the caliber isn't the beloved Lord's caliber and doesn't work quite right.
nothing to do with anything else.

LOL. Sigs shoot well but I dont use them because I dont need a 11# 1st shot trigger pull, an external safety, and an exposed hammer. They more accurate? Yes, but at 21 ft or less it doesn't matter. Glocks have a real good tendency to go bang at every trigger pull.I know exactly what the problem is. The problem is that it’s a Glock. Buy a Sig and this shit won’t happen
...Sig, the gun so advanced it shoots on its own...I know exactly what the problem is. The problem is that it’s a Glock. Buy a Sig and this shit won’t happen
Within my agency I’ve noticed this on occasion with some Glocks after some service life. Sometimes just needs the copper fouling cleaned out of the polygonal rifling or sometimes guys shoot a few lead rounds through them (even though you’re not supposed to shoot lead with the older Glock barrels). When we had a few more guns start doing this -even with relatively low round counts- we came to suspect some of the frangible ammo we were shooting may have been more abrasive than regular copper jackets - but only a hypothesis. Not sure if any of that applies to your situation.
Op, you need a "anti tumble recoil assembly" with that ammo....very common problem, most never even heard of. I am a stocking dealer, lucky for you. Send me like 75 bucks, and you gonna shoot like pro....
Lead bullets are fine in Glock barrels regardless of age, despite the CYA language that Glock uses in its literature.
As long as the bullet is well lubricated (a non issue with modern, polymer encapsulated lead) and the lead's hardness is appropriate to the chamber pressure, fouling will be minimal and will stabilize quickly (within 50 rounds).
Since I believe nothing I read and only half of what I see, I decided to test this about 13 years ago when I bought a Glock 17 (Gen 4). Back then polymer coated lead was not a thing so I ran plain ol cast lead bullets with the wax-filled grooves. Within fifty rounds a few short streaks of lead appeared near the muzzle, then never expanded beyond that by the time I ran 200 rounds (checking every 50) through the pistol. That was enough test for me.
Remember, 99% of what's in the literature included with a firearm in its box is meant for the absolute lowest common denominator.
HELL boys everybody knows that every pistol manufactured after God and John Browning designed and perfected the 1911 is only carried and used until it's unhappy owner saves the money to buy a colt of his own.
Shit can the glockenspiel and buy a CZ.
Not only will it shoot better, people won't make fun of you for owning one.

CZ gotta be better, a lot more gadgets to screw with to make it go bang. More is better?
Yeah, because de-cocking it before you put it in the holster is a big challenge, or at least it is for glock owners apparently
