Are the Glock 21 mags compatible with the 30S? I thought they were, but the only capacity listed for the 30S on the Glock website is 10. On others, it shows all possibilities like 15/17/33 for the 19. So I thought it would show 10/13 for the 30S.

I have 10 and 9 rounders. The 9 round mags sit flush with the bottom of the grip rather than provide a purchase for your pinky. It is a 30 body with a 36 slide so anything that works in a 30 will work in a 30s. I carry a 30s on occasion and it has replaced my 3" Colt 1911.

Yes. The 13 round G 21 mags are compatible with the 30s.

Amen Old Dog. The 30s grip length is shorter than the Defender. It's hard to beat the 30s for conceal carrying a .45 especially with 10 rounds of capacity. My Colt Defender stays in the safe.

yes, the 13 rounders will work in the 30s. I have qualified a couple times with my 30s and used a couple 13 round mags in the process.

X-GRIP makes a nice, very comfortable adapter for use with the 13 round mag in a 30/30s.

I don't care for the 9 round mags but instead run the 10 round mags with the Pearce PG-30 base plates to complete the three finger grip. The PG-30 should be an oem piece in fact. I would like to get some 13 round mags from the G21/41 guns.

9's, 10's and 13's work just fine in the G30/G30SF/G30S frames.
