Glocks are well-known due to their uncomplicated design and firing mechanisms with gentle triggers. Glock 19 is a compact gun, 6.85 in long, 21-oz weight when unloaded, using cartridges (9x19mm); its barrel length is about 4.01 in.

Why do we need a Glock 19 barrel?

It is simple to renew the firearm by attaching a modern Glock 19 barrel to improve accuracy and make the gun lighter. You can easily mount the scope on an upgraded barrel, not on the receiver. It’s recommended to change the barrels after 3500-5000 rounds, as the worn old ones can affect the firing accuracy.

How to change barrel on Glock 19

  1. While changing barrels, you need to remove the barreled action and the barrel nut, install the new barrel, tighten the barrel nut to the due torque, and then re-install the whole barrel (action assembly) into the stock.
  2. It is easy to swap barrels in minutes with a barrel nut wrench.
  3. For easier pulling out, use a barrel vise to align the barrel duly, using anchor points in the receiver that prevents scratching.
  4. A new barrel installation needs to be done in reverse of the old one removal. Slide the new barrel into the receiver, line up and tighten the V-Block, then put it into the stock. If the barrel is hard to fit into the receiver, you can sand the surface slightly with a 600-grit emery cloth.

How to clean barrel on Glock 19

  1. Usually, dirt and carbon deposit in the Glock barrel, which needs cleaning.
  2. First, unload the firearm.
  3. With the wet patch threaded through the slotted tip, insert the cleaning rod into the barrel breech end and swab out the chamber and bore.
  4. Push the crud out of the barrel with a cleaning rod, by forwarding it from the chamber to the muzzle and rotate the cleaning rod clockwise.
  5. Then use a gun cleaning patch, wet with gun cleaner, and run it through the barrel back and forth about 10 times.
  6. To clean the heavily fouled bore, use a dry bore brush, swab the bore about ten times with a wet rag.
  7. Take a cleaning toothbrush with some solvent and scrub carbon deposits off of the barrel hood and feed ramp.
  8. Wipe down the barrel outside and the chamber feed ramp with clean clout.
  9. Take microfiber towels and remove any excess cleaner outside and inside of the barrel until they start coming out clean.
  10. When the barrel is shining, it means that you have done its cleaning well.

FAQ

Can you put a longer barrel in a Glock 19?
4.02 inches is the longest barrel for a Glock 19. However, the length doesn’t influence the accuracy and round stability. Better velocity can be reached by changing ammunition or caliber.
Can you use a Glock 17 barrel in a Glock 19?
Such conversion is possible and not difficult. It’s necessary to put a complete G17 slide assembly to a G19 “long slide” barrel (like Alpha Wolf or Brownells).
Do threaded barrels add velocity?
4.5-inch threaded barrels can increase velocity by about 35 fps. The higher velocity, the flatter the trajectory, the easier conversion from one range to another. From 4 to 5 inches the velocity goes about 70fps and is quite linear in the 3-6 inch range.
Does a Glock 45 barrel fit a Glock 19?
The G45 can use the barrel for the G19, but it must be the long barrel option.

Glock barrels aren’t interchangeable across all generations. Several barrels will fit generations 1-3 while gen 4 and 5 are different constructions.

Conclusion

Barrels are consumable parts as they wear while shooting after some time in the chamber end throat area and on the rifling, caused by the burning powder, friction, and chamber pressure. It’s urgent to maintain the barrel duly to provide good firing performance. To choose a durable barrel, check its rifling and material quality.
