Glock FAQ

Frequently Asked Questions Conversion Kits for Glock Pistols


Will your kit work on my Polymer 80% or aftermarket frame?

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.


Are magazines and other parts in stock?

Yes, magazines and parts are in stock.


When will you have a kit available for the G26/G27 and G29/G30 Gen4 guns?

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.


Will the grey colored 15 round magazines made by another company work in my Advantage Arms conversion?

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.


Can you tell me which dealer will have one of your kits in stock?

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.


I wanted to purchase conversion kit directly from Advantage Arms, however, the website won't let me. Why is this?

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.


Can I Dry Fire my conversion kit?

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.


What type of ammo is recommended?

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 version here.


Is there any ammo that you do not recommend?

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.

Do I need to lubricate my conversion kit?

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


I'm having some issues with my kit not feeding or ejecting the rounds. What do you suggest?
  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

How do I adjust my rear sight?

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.

Can I get an extended barrel with a 1/2-28 thread on the muzzle end?

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.

I would like to purchase a conversion kit for my G22. Can I substitute an extended/threaded barrel for the standard one?

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

I assembled my conversion kit incorrectly and now I can't get it off my gun. What do I do?

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.

Can I get an extended barrel with a 1/2-28 thread on the muzzle end?

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.
