KKM Glock 17L Barrel


Called in to get this barrel for my G17L. Spoke to the man himself Mr. Magill who helped me throughout the call and a pleasure to speak to again. I have two other KKM barrels for my G24 and G17 Racegun, very accurate barrels for the last 10 years I have used them. Bore was very clean and no machining marks seen. Lock up on the hood is very snug, even when pushing down on it, there was barely any movement for a drop in barrel. Barrel comes throated for use with a variety of jacketed and cast boolit profiles. One of the reasons I wanted this barrel is for use with my reloads. Highly recommend this barrel from a very reputable manufacturer. Kudos to the GS team for picking out the best Glock accessories and awesome customer service.

5 star + Absolutely amazing for a drop-in barrel.


I ordered this barrel here at the Glock Store after considering some other barrels, and after the recommendation from an avid competitive shooter friend to try the KKM. I ordered the stainless to give my semi-custom G22 a little contrast and "bling".
The barrel dropped right in, fit PERFECTLY, locked up nice and looked great. A few days later, I was able to get it out and try it when I took my son out to shoot his new 17 I bought him.

My G22 was always a good shooter, but now it shoots LIGHTS OUT. The accuracy from this KKM barrel is phenomenal. Surgical precision. I was highly impressed, and will be ordering one now for my son's 17 to improve the accuracy of his as well.
Awesome barrel, highly recommend it! If you want better accuracy from your Glock, this will do it.

Top of the Line.


The fit and finish of this barrel is impeccable. It's being utilized in a Glock 33 and the accuracy is second to none. If you purchase one you won't be disappointed. So far no problems with feeding, firing and ejecting, including extreme defense ammo from underwood.

Great value for the cost


Perfect fit, drop right in without any need of final fitting. My only regret is that didn’t buy it sooner. Very accurate. KKM said 12 weeks for delivery, got it in 8.

Amazing Fit and Attention to Details


After I was unable to get the DD 10mm barrel for my Glock 20 I went with KKM because of the reviews and their reputation. I got 2 from them, the 10mm and the 10mm to .40 S&W conversion barrels in stainless. Talk about gorgeous and it took less time than originally quoted. Liked them so much I just ordered the 10mm 6" version. These are some very nice barrels. The fit is perfect and they also offered to make any needed changes in the future if Buffalo Bore makes a new hard cast round that has feeding issues, as reported with some aftermarket barrels. KKM has designed their barrels with Buffalo Bore and Underwood in mind. Not only their hard cast, but their Lehigh rounds too. You cannot go wrong with these barrels.

Above and beyond


I recently had an old Glock 30 match barrel from Precision that was a bit too tight for some jacketed factory HP ammunition. I emailed Precision and told them about my issue. They said to send it back with the matching ammo so they could see the fitting. KKM opened the old barrel slightly but then sent me a new match Glock 30 as well. This is above and beyond excellently service! Their barrels have often shot better than other barrels so I would highly recommend them! Richard l Fung ( retired police)

Good barrels


Good barrels ,very accurate, tight fit which makes these barrels excellent!!

Great Craftsmanship & Great Value.


I bought this barrel for my G21 Gen4. This barrel is what I consider “Plug n Play”! Very easy to install, accurate & a breeze to clean. Highly recommend!!!

Best Glock drop in Barrel period.


I install KKM barrels on all my Glocks. They are extremely accurate. You can shoot just about anything through them without issue. I have yet to find a better drop in barrel for the price and I had tried several.

From Glock 20 to Glock 40 in under a minute...


One of the best barrels on the market.
Will buy more.
