Custom 15 Rd Windowed 9mm RIA Blued Mags - 2nd Generation
Click To Enlarge

These are our second generation 15 round magazines for Armscor Rock Island Armory (RIA) High Capacity 2011-style 9mm pistols, such as the RIA 51679 Tac Ultra FS and 56645 Pro Ultra Match HC.  Specfically, these are for the RIA A2 HC series pistols that use the 17 round 54180 magazine and are designed for smooth reliable feeding. They are not for the traditional 8-round 1911 pistols (I would recommend Wilson Combat or Tripp Cobras if you have one of those pistols and lots of websites carry one or the other).

These mags hold 15 Rounds and have a blued finish - RIA uses the same length of tube but a different base plate.  Greg Cote does sell those +2 round base plates if you are interested.

These are custom made by starting with Mec-Gar P16 .40 S&W magazine tubes that have a 10 round limit.  We remove the dimples that limit the capacity so they can now hold 15 rounds and modify the feed lips to properly handle a 9mm cartridge.  A ceramic dry lube is also added to the inside surface of the tube.

Note, the magazine tube will have P16-40 marked on it but they have been modified to reliably feed 9mm - we will put a 9mm label on the base plate to identify it if you order a Dawson - The Para plate option will not have a sticker.

Note, these have the full length feed lips and will not feed 22 TCM without your shortening them.  I do not have a 22 TCM pistol to test with so that may be something we can add in the future,

These mags use custom modified followers (by us & part of our secret sauce) and the original Mec-Gar spring.  These will lock the slide open on empty (an early version did not but these do).  The feed is really smooth - far smoother than the originals thanks to the modified follower and ceramic dry lube.

These custom mags were tested specifically with a 56645 Pro Ultra Match HC.  These magazines hold 15 rounds.  If you want 17 like the original, then youl will need to source them.  I prefer base plates that lock into place so all of these magazines have Dawson plates unless you opt to not get one.  This option to go with the original Para-style base plate is for people who plan to replace the base plate anyways.

You pick the base plate option you want

You can choose whether you want a Dawson base plate (which you need for the pistol to work with a Rock Island A2 HC funnel or if you want the original Para-style base plate.  Only pick the Para plate if you plan on replacing it with another model - the Para base plate will not fit in your Rock Island.  I added this option because some guys already own base plates and don't want to pay extra for the Dawson.

Competition Arredondo Spring and Follower Option

If you wish, you can have us install a 10% strong magazine spring and competition follower - both from Arredondo.  Note, the Arredondo follower is for competition - it has excellent reliability but does not lock the slide open after the last round.

Please ALWAYS Test Your Magazines

I do have something I want every reader/buyer to remember:  PLEASE Always test the magazines before you need to rely on them - you must verify that a given combination of pistol, ammo and magazine are reliable and this is true for any firearm. My liability is limited to the purchase price of the magazine and they are warranted against manufacturing defects only (not including any required feed lip tuning) for 90 days. 

Do you have a brand new pistol?

A brand new RIA pistol will have feeding problems right out of the box because it does need to wear in and this may take 100-200 rounds.  When you get a new RIA pistol, be sure to clean and lube it.  I would then recommend cycling the slide a few hundred times (literally) to help smooth things out before you get to the range the first time.   It may still have some feeding problems after this but they will be a lot fewer.  By the way, the need to wear in or break in is very common in firearms so don't get discouraged right away.

Dawson Plates

We do sell Dawson base plates if you wish to have one that extends further than the included Mec-Gar plate (the Mec-Gar plate fits fairly flush and is easy to insert and extract).  FYI: The +100 Dawson plate sticks out just about as far as the polymer plate so a +200 or +300 plate would actually make the magazine taller - note that the plates add height only but not capacity.  Please click here if you are interested in Dawson plates.


Due to irrational firearm hysteria, I will not ship magazines to locations listed in the USCCA magazine limit guide page that prohibit magazines of this size (16 rounds is my stated capacity) plus try to maintain a list of other areas. I will not ship disassembled "magazine kits" to those locations either - sorry. I can't export them either - I hate having to put all this legal stuff in but I must.  It is the buyer's responsibility to ensure compliance with all applicable laws and regulations before buying these magazines.

We can't ship these magazines to the following states:

  • California: 10 round limit
  • Colorado: 15 rounds
  • Connecticut: 10 rounds
  • Hawaii: 10 rounds
  • Illinois: We will look up your city and county to see if you have limits.  For example, Chicago and Cook Country are limited to 10 rounds.  
  • Maryland: 10 rounds
  • Massachusetts: 10 rounds
  • New Jersey: 15 rounds
  • New York: 10 rounds
  • Washington D.C.: 10 rounds

This product is export controlled by US Government Export Regulations.  We will not export to any country.

Terms and Limit of Liability

This is for one magazine - the pistol in the photos is not included.  We are not liable for any damage or injury resulting from use or misuse of this magazine.  The buyer assumes all liability.

Please do not use Paypal to purchase magazines.  We do take American Express, Master Card, and Visa so please use one of those methods.  Sorry - Paypal's policies do not allow for many firearms and parts transactions but we have quite a few pro-gun customers who do like to use them for other products we sell.
