Your Questions Answered
What ammunition does it run best with?
Based on our range testing, the GLOCK 30 GEN 4 cycles 115gr and 124gr FMJ range ammunition without issue. We experienced one failure to feed with a specific brand of 147gr subsonic ammunition during testing. For defense loads, we recommend testing your chosen carry ammunition for reliability.
Is this model compatible with other GLOCK magazines?
Yes. The GLOCK 30 GEN 4 accepts magazines from the GLOCK 21 (.45 ACP) series, including the 13-round magazines, though they will extend past the grip. This provides flexibility for range use or as a backup magazine.
What comes in the box?
The pistol ships with two 10-round magazines, a cable lock, cleaning rod, magazine loader, and the standard GLOCK documentation. It includes the multiple backstraps for the modular grip system.
