Included Parts:

Glass Filled Nylon Magazine Extension

Hardened Steel Locking Plate

Extra Power Spring  


Note: When installed, your magazine will be longer than 140mm, therefore these are not legal for USPSA Limited and L10

Great product!

This is exactly what I was looking for. I have the xd9, mod 2 and it added 4 to my 16rd magazine. I'm definitely ordering another to add 4 to the 13 Rd mag. Sturdy, not cheap, good spring. Solid product.

Received the item in 2 days. It was a quick and easy install. Loaded the ammo easily and it seated properly in the pistol. I am extremely pleased with the product.

AGP mag ext 9mm

- 27th November 2013

I guess I got the exception to the rule. Once installed the mag would NOT lock up in my stock XD( I work in a gunshop , so I tried it with several stock guns. I had to trim the small raised lip with x-acto to fit. Would NOT lock up on my target XD without extensive tooling (think Dremel, x-acto, sandpaper, JB Weld) Would have sent it back but I need one for a match the nxt day-as I had dropped my mag and cracked the end cap the day before. [PG NOTE: We suggest you contact AGP as there may have been an issue with the part you received. That said, not knowing exactly what XD model the extension was installed on, it is hard to offer a suggestion.]

Absolutely amazing

Purchased Friday, received in the mail the following Monday. Love the fast shipping!

The product was very easy to install and was on my magazine in less than a minute. I was actually able to load five extra rounds to my factory 16 round magazine (9mm) with no binding. I'm extremely pleased with the quality and highly recommend this extension to anyone wanting to add a few extra rounds to their capacity.

I'm ordering another one for my second magazine!

My testing got different results...

"Our testing has found that you can easily add five extra rounds to the 16 round 9MM XD magazine..."

Well, it says right on the package that it adds 4 rounds, and sure enough it adds 4 rounds. I can get exactly 20 rounds - no more and no less - in a 16 round magazine with these installed. As another user posted, using the included spring seems to make no difference, either in the mag function or in the mag capacity.

For those interested in using these for USPSA or 3 Gun Matches, they are exactly 143mm long, or just a bit too long to be legal. Just hope nobody checks your mags...
