Magpul just released a 21rd 9mm Glock magazine, and it’s MSRP is something like $19.99. Oh, and it’s 140mm, so it’s good to go for USPSA Limited.
Oh, and it’s a Magpul magazine, so it probably works great too. I’ve been using a handful of the 17rd Magpul magazines for a while now, and I’ve found them to be as reliable as my Glock brand Glock magazines (and they’re cheaper).
Thinking about USPSA Limited Minor, most folks who shoot in that division with a 9mm pistol end up buying a Glock magazine for $25, and then a magazine extension from one of the major players (Dawson, Taran Tactical, etc) for $25 or more, to get one magazine that’ll hold 21 rounds. So that’s $50 (or more if you factor in shipping) for one magazine. This has been the way of things for many years for folks shooting Limited Minor, but now that’s changed.
I think the biggest area where this is helpful is for people looking to get started in competitive shooting, but don’t want to drop a ton of money before getting started. With these 21rd magazines, and the 2 or 3 magazines that their Glock came with, and one or two of these 21rd mags, and they’ll be good to go shooting Limited for a few USPSA matches. I dig it.
Magpul, keep doing what you’re doing.
