No, The Advantage Arms conversion kit for the Glock pistol is designed to fit and function on factory stock Glock receivers. Our kits were not designed for, nor do we indorse, using them on the Polymer 80% or any other aftermarket receiver.


Yes, magazines and parts are in stock.


No special kit required for the G26/G27 or G29/G30 Gen4 guns. Our L.E. 26/27 conversion kit will work on all G26 and G27 frames, including the Gen4. Our LE 29/30 conversion kit will work on all G29 and G30 frames, including the Gen4.


No. From the feed back we're getting they do not work, lots of feeding issues reported. We offer our own 15 round magazine for use in our 17-22 and 19-23 kits. Our 15 and 25 round magazines require the use of CCI 40 grain round nose ammunition and are not recommended for the 26-27 kit.


Unfortunately, we cannot. We ship to a distributor, who then sells to the dealer, so we would have no way of knowing which dealers recently received kits.


We have temporarily suspended Retail Sales for all of our conversion kits. This is being done while we get caught up with our distributor. During this time, anyone wishing to purchase a conversion kit, will need to do so through a dealer. We do not have an estimated date as to when retail sales will resume.


Dry Firing is not recommended and should only be done when it's required to remove the conversion slide from the frame. Excessive dry firing can damage the barrel and firing pin. We machine a small relief at the top of the chamber to help eliminate this problem. Click Here to see a picture of the relief.


CCI 40 grain round nose MiniMags, not hollow points, is the only ammo we recommend with complete confidence. Other brands like Federal AutoMatch and Remington Golden Bullets work quite well but do vary from one production batch to another. Printable


We do not recommend Stingers or any other Hyper velocity ammo. Also, the kits do not function very well with Federal bulk pack or PMC ammo. DO NOT use Remington Thunderbolts as they will lead up the barrel. We do not recommend any Winchester ammo.

Yes. We recommend that you put a drop of oil on each of the slide rails and one drop on each of the 3 flat surfaces on the barrel. Spread the oil with your finger. Printable


1 - Use the recommended ammo.
2 - Your Glock should be factory stock. No aftermarket parts like the connector or trigger bar.
3 - Lubricate your kit, it will not function properly if you're shooting it dry.
4 - Watch for "limp wristing". 
5 - Do not allow any portion of your hand to touch the slide while shooting.

To move the point of aim left, move the blade to the left by turning the windage screw clockwise. To lower the point of aim, move the blade lower using the elevation screw. The elevation screw will turn 360 degree's, moving the sight from its lowest point to its highest point. You will need to turn the elevation screw and watch closely to see what direction the sight is moving. Click Here for an illustration.

Yes/No. Our barrels are only 7/16 in diameter at the muzzle so the barrel cannot be threaded 1/2-28. However, we do make a threaded barrel and adaptor so you can use your favorite 1/2-28 threaded accessories. This is currently available for the following models: 17-22, 19-23, 20-21 and 26-27. If you would like a Threaded Barrel Click Here


The 17-22 extended barrel is 4.875" long. The 19-23 extended barrel is 4.425" long. The 20-21 extended barrel is 5.050" long and the 26-27 extended barrel is 3.88" long. If you would like a Extended Barrel Click Here


No. The extended/threaded barrels must be purchased separately.


This procedure assumes that the ejector was incorrectly installed. If the ejector is incorrectly installed it will keep the breech from closing and will disengage the firing pin from the trigger.
You will not be able to remove the unit while it is cocked. If you can't release the firing pin by pulling the trigger then you will need to do the following:
1. You will need some kind of tool to push the firing pin sleeve forward, I
like to use a 3/32 pin punch, however a small screwdriver or small drill
will also work.
2. Pull the slide back and lock it open with the slide stop.
3. Turn the gun over and you will see the firing pin and sleeve at the rear
of the slide. The sleeve is in front of the firing pin. See Picture 1.
4. Using the tool you've selected, push the spring loaded firing pin sleeve
forward holding it there. With your other hand, remove the cover plate on
the back of the slide. See Picture 2 and Picture 3.
5. Once the cover plate is removed you can pull the firing pin assembly
out. See Picture 4.
6. Release the slide stop and slowly close the slide.
7. You should now be able to remove the side assembly per the instruction
in the Owner manual.
The conversion ejector may have been damaged if it was pinched between the
slide and the barrel. If the little slot that engages with the tap on the
barrel is tight you can open it up a bit with a flat bladed screwdriver.
