Advice for Keeping a Glock 19 Threaded Barrel’s Threads Clean

Have a Glock 19 with a threaded barrel, but haven’t splurged on a suppressor or a compensator yet?

Make sure you keep that thread protector on there till you do.

Which brings up another interesting conundrum. You still want to keep the threads clean so they’ll be ready when you do add an attachment.

A word of explanation is needed here.

You Don’t Want It to Get Seized

First, Glock’s barrels are made with a DLC, and most Glock aftermarket barrels are treated with extremely corrosion resistant finishes with high permanent dry lubricity like black nitride or titanium nitride.

This does not (read that again) mean that these barrels and the threads they sport are completely immune to problems like corrosion, tar accumulation, and seizure.

If you let the threads get really dirty, and never do anything about it, and some oil or grease gets in there and combines with the fouling…you just might have a very hard time getting the thread protector off when you want to.

Is this likely to happen? Absolutely not. But it could, and moreover, when you fire a Glock 19 with a threaded barrel that has a thread protector installed, you will be blasting the threads with fouling, even if not as much gets in there as would be the case if you were running a suppressor.

It’s not as important as keeping your bore clean, to be fair. Even with a seized thread protector, your gun will shoot just fine. You just won’t be able to tack on any muzzle devices.

Just make sure you clean it every once in a while after you’ve had an extended trip to the range. Take off the thread protector and hit the threads with some solvent, then scrub them with a nylon brush (don’t use steel or brass), dry them, and give them a little bit of oil before reinstalling the thread protector.

If Applying Loctite…

Some shooters apply Loctite to the threads of their barrels before attaching muzzle devices like compensators or suppressors. The idea is to create a surer bond between them, and by preventing incidentally loosened suppressors, this can help prevent issues like a baffle strike.

Anyway, we’re not here to weigh in on whether or not adding Loctite is good or bad. All we can say is that if the threads aren’t completely clean, it will interfere with adhesion.

So, before applying any sort of thread locker, make sure you totally strip off any residue that’s on the threads, then do not apply oil. To dissolve the remaining residue before applying a thread locker, apply a little bit of rubbing alcohol to strip away anything that’s left.

Here for a New Glock 19 Threaded Barrel?

Don’t have a threaded barrel for your Glock yet? Don’t get it from Glock – they charge too much. Get it from NineX19 instead. They produce barrels for popular Glock handguns, including threaded barrels that are fluted and finished with advanced nitride coatings.
