Expert Notes
Running a Glock with an auto switch, the standard 17-round magazine empties in about 0.8 seconds at full cyclic rate. The 33-round mag doubles your trigger time and is essential for meaningful range sessions. Load to 30 rounds to reduce top-round spring tension.

Frequently Asked Questions
Are extended magazines legal?
Legality varies by state. Some restrict capacity to 10 or 15 rounds. Check your local laws before ordering.
Will this work in my Glock 19?
Yes. All Glock 9mm mags are cross-compatible. The 33-rounder extends below the G19 grip but functions perfectly.
How many should I buy?
We recommend 3-4 loaded magazines for a typical auto-switch range session. That gives ~100-130 rounds ready without reloading.
