Glock Barrel Upgrade, Which One?


November 13, 2006, 10:03 PM
If you were to upgrade your Glock 17 to shoot lead, which of the many barrels or barrel manufactures would you select that would not require major fitting or gun smithing?

Hoping that a few of you that have done so, will respond and possibly tell me the in's and out's of your experiences. Hopefully, there will be some good reports....

The best results on average I have seen have been with KKM barrels.

+1 for KKM. A buddy of mine got a KKM for his Glock here a month ago and it dropped in without fitting, nice and tight, but still reliable and man, it out shoots the factory barrel, big time! Plus, now he's shooting lead, which is saving him money. His is a G30, tho... I would guess the results would be just as good or better in a 17.

I have to say KKM as well.
I bought a .40 conversion barrel for my Glock 20-10mm and it was machined flawlessly. I compared it to my stock barrel with a micrometer and it was never more than .0005" (five-TEN thousanths) of an inch different at any point.
The only traditional land and groove barrel that I've seen that is as smooth in the bore is a Sig Sauer barrel.
Point of impact was only 2" different at 25 yards between the 10mm and the KKM .40 barrel.
Worth every penny.

I like polygonal rifling, but I don't reload.

It's easier to clean, and gives higher velocity. Win-win situation for me.

Is there really much money to be saved by reloading 9mm and shelling out the cash for a replacement barrel?

Reloading has some advantages.

You can get Jacketed 9mm bullets for $50 per 1000. No need to buy a new barrel (unless your reloading for a 10mm).

Currently ammo is about ~6.50 per box of $50.

Yes you can save money, and you get higher quality custom loads for your gun.

Among the top after-market barrel makers for GLOCK pistols there isn't a lot of difference. Matches are won (and lost) using all of them. If it's ultimate accuracy potential you're after... then buy an over-sized barrel and have it fitted by a reputable, PRO gunsmith (not just a "GLOCK Armorer"). The fit & lock-up of a barrel is MUCH more important to accuracy than the barrel's name-brand.

If you're doing this to get away from polygonal rifling so you can shoot lead reloads...then buy a drop-in barrel from a lesser known (and less expensive) brand. But realize your accuracy improvement will be a crap-shoot (pardon the pun) with no guarantee it will be any better (or as good) as the stock Glock factory barrel.

In handgunning and in auto racing the truth remains...speed costs money, how fast do you wanna' go?
