FAQ
Is this a true drop-in barrel, or will I need a gunsmith?
This is designed as a drop-in barrel for the Glock 43 and 43X. It should install directly into your slide without modification, but as with any aftermarket part, we recommend checking fit and function thoroughly before live fire.
Does this barrel come with a thread protector?
No, a thread protector is not included. The threaded muzzle is 1/2×28, a standard size, so you can easily source a protector or your chosen muzzle device separately.
