EFK Fire Dragon Pistol Barrels. These Are Some Of The Finest Pistol Barrels Made In The World! Because of the care exercised in manufacturing and our refusal to compromise on any step of the process.image

The end result is a good-looking, top-quality barrel with consistent, accurate and long-lasting performance. And don't forget the service. We deal with our customers on a personal level to ensure their complete satisfaction on all of our products.

All threaded barrels come with a thread protector.

Industry standard is 150 rounds to break in a barrel before threading any device on to the barrel.

When a barrel contains the word "conversion", it means these barrels work only in 40S&W and .357 converting to 9mm.

You cannot go from a 9mm to a 40S&W or 357Sig

For best results converting to 9mm from 40 S&W use a 9mm mag.
