Needed threads
I needed a hard to find .40 threaded barrel and this Silencerco did the trick for my Glock 22. Very fast shipping, barrel works, what's not to like.

Surprisingly great barrel
Purchased the Silencer Company threaded barrel for Gen 3 Glock 26 for obvious reasons. Was skeptical at first due to a narrower feed ramp than stock G26 barrel. However it ate everthing from Gold dots, FMJ RN, 115GR. -147GR. Whats more improved accuracy! A company known for Suppressors, they hit a home run as far as Im concerned with the treaded barrel for Glock 26. Well done.

Excellent fit and finish! Took less than 30 seconds to install! Groupings are also improved!!

Great Quality, Great Value
Title says it all. High quality that won't break the bank, especially if you get it on sale around $135. Swapped it in to replace a Faxon barrel (part #100-026-100WB that did NOT lock up in battery in my cheapo Swenson slide (part #907282 over at MidwayUSA). 1/2 x 28TPI makes it easy to share your favorite can or compensator across multiple firearms, including 5.56mm if you have an appropriate multicaliber can (many 9mm barrels are 1/2x36 but most 5.56mm barrels are 1/2x28). Thread protector is included, O-ring is NOT included - but you can get a whole pack of an appropriate size at your local hardware store or Fastenal for about a dollar. Rifling is 1:12 (OEM Glock is 1:10 and supposedly stabilizes a wider range of bullet weights well) but hey it's going into a G19 not a sniper rifle, most of us won't shoot a handgun past 25-50 yards - if you're worried about rifle twist significantly degrading accuracy in a combat-style handgun, you should probably invest in a multi-thousand dollar bullseye-tuned 1911 instead... 1:12 is close enough for minute-of-badguy, fun shooting, or amateur competition in my book... Fits perfectly, locks up tight and threaded end protrudes perfectly in my cheapo red-dot-ready Swenson slide (part #907282 over at MidwayUSA). Feeds and ejects perfectly, so far only fed it a bunch of factory Prvi Partizan 124gr FMJ due to ammo scarcity. Easily capable of 2" groups at 25yds from a sandbag, using OEM trigger and 3.5lb connector - probably capable of better accuracy if you have a lead sled or high-quality trigger.

Great product
I'm using this on my Glock Gen 4 working great was a little tight on lockup but a little gun oil did the trick. I'm using silencerco s hybrid 46 and it's not the lightest but the combination is working flawless couldn't be happier.

Quality silencerco product
Bought this on sale after I got a combat armory threaded barrel for g19, that would touch the guide rod lightly. After being told all barrels are the same its safe to say that isnt so! Silencerco barrel is nicely finished and doesnt touch the guide rod. Contacted combat armory, no response or help! Buy it right the first time with a quality product.

Reliable Suppressor Host
I installed this in a Gen 3 Glock 22 to use as a suppressor host for a SilencerCO Hybrid. I'm only a few hundred rounds into the new barrel, but so far the fit and function has been 100% and it works great with the suppressor. I will definitely look at another SilencerCO barrel for my Glock 17.

Worth the cost
Easy to install. As with all Glocks, installation takes just a few steps. This barrel has the two features I wanted--threaded for future add-ons and a little more length. The included thread protector is a plus. I purchased this product to complete a build. The next barrel I purchase will probably be this brand.

great product
I paired this with a Brownells slide. Dropped right in, no fit issues at all. Have over 900 rounds through it, both brass and steel case, no issues. Grouping is as good as factory Glock, if not better. Easy to clean up as well. very happy with purchase.
