Note: This kit works with Gen 4 G21s and G20s only. Do not use with other generations. For use with factory frames only.

Aftermarket parts such as trigger bars and connectors, especially the Ghost Connector, can adversely affect the function and reliability of your conversion kit.

The front and rear sights are removable GLOCK OEM sights. The rear sight is adjustable for both windage and elevation.

The slide will lock open after the last round in the magazine has been fired. Our unique patented magazine design and heat-treated steel lock open insert allows us to offer this special and desirable feature which you can only find on 'Advantage Arms' .22LR GLOCK conversion kits.

Glock incorporated an internal firing pin safety into their guns. We thought it was important enough to include it on our conversion kits as well. Our internal firing pin safety is designed to eliminate accidental discharges from dropping the firearm.

All Aluminum parts are Anodized Per Mil-A-8625 with a matte black finish. All steel parts are heat treated with a Black Oxide Finish. The barrel is made from heat treated 416 Stainless Steel.

Installation is simple and does not require any modifications to your GLOCK pistol. Simply remove the GLOCK magazine and slide as outlined in your GLOCK owner's manual. Now slide the "Advantage Arms" slide onto the frame, until it engages with the slide lock. Check to make sure that the slide lock is in its most upward position. Insert the conversion magazine. You are now ready to shoot.

A one year factory warranty covers any defects in materials or workmanship.

We highly recommend Remington "Golden Bullets" for everyday plinking and CCI MiniMags or Federal Automatch  for better accuracy.
