Rock island arms 22 TCM, magazines

[Sun Tzu warrior]

Hello, been awhile since I have posted,
Anyway, I have an RIA 22TCM/ 9mm doubles stack combo. I really like it, but....... They only come with 1 magazine. I would like more, before the political climate relegates me to no choices. I cannot find mags, I have heard they maybe Beretta, 38 super slightly modified. Can anyone here confirm this, and if so, what modification?
Thanks in advance. A source with in stock factory mags would be even better. Thanks folks

If you have not checked the Rock Island sections on 1911 forum they may be able to help. https://www.1911forum.com/forums/rock-island-armory.64/

I use Mec-Gar P-18 magazines, I can see no difference in performance with or without the angled cut.

Currently out of stock at Midway.

Greg Cote is also a good source, especially for odd-ball mags, but they also appear to be out of stock
