Good evening to you!! Yes the Keltec Sub 2000 uses common FN 5.7 pattern magazines. The ProMag (link below) will fit your Kel-Tec sub2000. Hope this helps. Have a good rest of your day. Enjoy your Kel-Tec I love mine.

Hi Luis, yes sir, the 5.7 SUB2000 uses common 20 and 30-round FN Five-seveN pattern magazines. It can also accept aftermarket mags such as ProMag’s 55-round drum.
Stay safe & have a great day!
