Make a 15 round magazine, 10 RD Advantage Arms.

[RamRoddoc]

I had mentioned this before but needed to provide a detailed walk through on how to convert The Advantage Arms (AA) 10 round full size magazines to 15 round magazines with factory AA Glock 26/27 parts for a measly $9 + shipping and a bit of drilling a 15 round AA Glock full size magazine can be had reasonably. The old link to increasing magazine capacity:

Link for Glock 26/27 parts parts (Magazine follower $5 and magazine plunger $4):http://www.advantagearms.com/mm5/merchant.mvc?



Depress the magazine plunger with a punch and gut the magazine. This is required for routine maintenance/cleaning.

These are the original parts and the AA factory Glock 26/27 parts to be swapped but hold on a bit of drilling with a 25/64" drill bit is required.

Care needs to be given to not go too far with the drilling of the magazine follower channel. Caution, easy to lose a finger doing this (take any rings off).

Go about this deep but not through the top of the magazine follower channel.

More to follow

I angle the rear portion of magazine follower a bit with a file or dremel tool to allow it to ride a tad further up in the magazine.

Clean any burs out with file or sand paper and reassemble the AA Glock 17/22 magazine with the AA Glock 26/27 parts. There is a slight difference in the deck height of the follower as seen in this image but it doesn't seem to affect function. The follower needs to come up enough to allow the slide to lock to the rear.

But RamRoddoc I'm broke and can't afford the parts and shipping. Rest assured their is a cheap way to get 14 rounds into the magazine and not spend a penny for parts.

Just take the old AA Glock 17/22 follower and whittle it down and skip the magazine plunger.

Hey doc, I'm just not Gucci with the floor plate not having the magazine plunger in it securing the plate from moving and I'm not duct taping the thing. Well ok, then make a plunger tube follower. I made one out of a .44 lead cast bullet on a drill press-turned into a lead lathe. The old plungers are steel. The new ones are plastic and it should be easy to trim these to fit. You will lose another round but have reliable 13 round magazines.

Who wouldn't want more?

Lastly don't do this if the liberal communist have taken control of your state or local area, because you would be....

Thanks for the info!


I will definitely try that if I can get my kit to cycle more than times in a row!

(Of course, I have only been able to try a couple different types of ammo, so that is probably the issue.)

 

[RamRoddoc]

Now how about making AA magazines run right if they aren't.

The factory kits have made a few changes and magazines have been updated at the factory but for what ever reason I still have issues with them desiring a specific brand/type of ammo. I really don't like that. Many reports of a simplistic correction with just a dremeling of the front feed lips to melt them/arch the tip. I'm sure it is a good method and I use it but go further.

Watching the magazines for wear, a faint visible line appeared on the right of the magazine is noted and identified as fat to be reduced. This line was visible after about 30 rounds fired.

The magazine lip should be flush on the newer magazines. On some older magazines they were elevated a bit. Curving the tip of the leading edge of the magazine lip enhanced ejection as the rim would catch the beefy tip and jack things up.

Upon firing as the slide recoiled pulling the empty case out of the chamber it would catch the lip of the magazine and prevent reliable ejection. Some ammo just plain refused to eject. The drag marks toward the left rear of the magazine faintly appeared on the 2013 magazine in 30 rounds or so. Some magazine material needs reduced.

Here are some comparisons:

A hand file keeps things straight and takes plastic off a bit slower but much more forgiving if an error occurs.

Enhanced performance of the AA magazine's is realized but more can be done, follow along.

A fairly simple enhancement to any semi-auto is to polish the feed ramp or throat. I often use just use a spent case but the AA feed ramp is rather small and an aluminum .22 Cal cleaning kit rod fits the channel exactly.

Some fine grit paper 800-1000 should do the deed. The intent is not to remove metal but to polish it. Machine marks are often an easy to observe warning that metal is being removed as they appear then thin. Don't erase them.

Like this:

Next seems to be a recurring issue with Advantage arms. The extractor has so much meat on it and angle that as the slide moves forward into battery it shoves the extractor off the rim then plays hell to grab it again under recoil. It needs a bit of a diet as well.

Here are comparisons of without an extractor reduction and with extractor reduction.

The extractor can be seen lifting up and nearly off the rim.

 

[RamRoddoc]

The extractor face needs a reduction and polish.

A pair of vice grips make for a protective guard and assist in holding the small part while a small file is used to re contour the face which contacts the breech area.

I tried to not take metal off the tip but it was nearly impossible, so don't take too much or you will need another extractor. After file then on to paper 800-1000 grit is used to polish the extractor face. Make sure the metal is flat and not skewed to the side. A flat contact makes for a fat scrape line on the paper.

I use punches but a drill bit could be used as well to slip in the extractor to check progress and reduce lifting. My 2008 kit I pretty much got nearly all the lifting off the extractor but this 2013 kit the extractor still lifted some but much better than when I began. It should run well with a wider selection ammo and 15 round magazines......

Excellent work Chris!

Excellent work Chris!

Can't stand a gun that won't run well. Most can be corrected with minimal effort. Thanks Darren.

Thanks again for this thread!

I tried filing down the right side of the mag for my G19 conversion. I could actually see where the slide had been dragging.

(Knock on wood.) So far-it is like a whole new gun! I am very excited to have this thing functioning properly!

Thanks for the great info! (I was about ready to chuck that kit in a river-but now it seems to be purring along very well!)
