  1. Lemme see if I got this straight..I purchased an RIA 51679, full rail, magwell, hi cap 9mm. If I order the P18 mags from Greg i will have to get the Dawson base pads and Arrendondo inserts? Sorry if I am beating a dead horse, new to the whole "modifying magazines" thing...

    correct.

    Loving mine.

  2. The mec-gar 17 round mag body is confirmed - that works. The one RIA supplies their guns with has an IPSC international sytle baseplate that works and fits in the magwell. If you have the standard mec-gar mag with the sheet metal floorplate it won't work, and will require you to change the baseplate or trim it. The Dawson precision basepad with arredondo spacer is confirmed to work in the mec-gar mag tube.

  3. You've got some trimming to do -

    On major problem is that you can't get the insert into the Mec-Gar magazine, as it is a few milimeters shorter than the factory para mag. The ribs in the mag tube interfere with the insert getting in. You'll have to get that to fit without affecting the integrity of the insert (we wouldn't want it to weaken and get in the way of a spring). Even without the insert, the base pad gets hung up with several milimeters to go. It is catching on the magwell. It will at best need to be reshaped.

  4. UPDATE - I ran the Mec-Gar P18 mags with Dawson basepads, Arredondo inserts and standard P18 mecgar spring and it ran like a top today. 21 rounds loaded and everything worked, but it was tough to seat the mag. With 20 rounds loaded it was easy to seat and everything fed fine.
