Gen 3 Glock 34 Barrel upgrade.....any preference for paper target range use?

KKM. Bar-Sto is just too tight for a pistol unless it is strictly a target gun. The KKM barrels are about as good as it gets. Not loose, not tight. Just right! Very easy on brass.

Had a Glock 35 with a Barsto barrel that ran fine.

I have a KKM on my G19...good to go, but you need to pair it with good ammo of course.

True story: this week I got some Blazer Brass 124 and suddenly 1/3 of the rounds make a left turn lol. When I shoot my "good" ammo (i.e. Magtech, Geco, American Eagle, PMC) no probs. I do have some black hills stashed in the back of the safe that I will only shoot after the Brandon administration, Felosi, and squad members leave office.

Brownells barrels aren't bad either:

First thing to do is check over the barrel you have. Look at the crown, look at the locking lugs, try to push the chamber down while the gun is locked up. See if there are actual problems with any of those features, determine if you can fix them.

Lots of aftermarket barrels have crap crowns, and if that's your issue a $25 rotary tool can fix it and it'll probably shoot better than some other random drop-in barrel.

The rifling is rarely an actual issue, but some can be picky with ammo, so if there's no obvious fit/finish issues, try some different loads and see what happens. Your new barrel may hate your ammo as well.

If all that doesn't add up to an accurate barrel, my first choice would be KKM or a hand fit Bar-Sto, but only because I shoot bare lead. If you're only going to shoot FMJ, a factory Glock barrel is extremely good and should be cheap.

If you want bling, take your pick, most come from the same supplier and are only engraved/plated by the company selling them.

Thanks everyone.....i think i'm going to try the Bar-Sto gunsmith option as they are offering free shipping for the holiday. I have a good friend who's a gunsmith and he kindly offered to show me how he fits the barrel. Should be awesome to see.

I bought a KKM 9mm conversion barrel for my G35 and it shot 2.5" high and right at 10 yards. I was not impressed.

It’s my humble opinion you have purchased the best aftermarket barrel you can to enhance consistency in your Glock.
If there is a better one I am unaware of it.

Bench shoot it side by side with the barrel you had. At 25 yards you will be amazed at the difference.

If you could direct upload images easily here without a hosting service I would show my own testing images.
I contribute a above average amount of info/research on another forum simply due to the ease of sharing it.

I am sure you will enjoy the finished product.
