How this list was ranked
These are the best 9mm magazines that GunDealAlerts holds a dated price record for — 4 of the 4 that qualified. They are ordered by how active the deal flow is (the number of r/gundeals postings behind each 90-day street price), and then by how far each product’s lowest tracked price sits below that street price. Nothing here is weighted or scored; it is a sort order, and every figure above is the real tracked price with the date it was tracked.
This is a price-data ranking, not a range report. Nobody at GunDealAlerts has shot every product on this page, and this list does not pretend otherwise. What it can tell you — and what a reviewer who has never seen a price history cannot — is which of these actually come up for sale, how often, and what counts as a good price when they do.

Frequently Asked Questions
How are the best 9mm magazines ranked on this page?
By GunDealAlerts' tracked price record: first by how many r/gundeals postings sit behind each product's 90-day street price, then by how far its lowest tracked price falls below that street price. It is a ranking of what the price data shows, not a review.
Are these hands-on reviews?
No. This page ranks products by tracked price data only. GunDealAlerts pages that carry a first-hand opinion say so and carry the author's name and background.
