Washington state has passed a bill essentially ending high-capacity (anything over 10 rounds) magazine sales after 1 July, which the governeor is expected to sign in a heartbeat once it hits his desk (He personally considers high capacity magazines/platforms to be "weapons of war.")
I'm adequately covered by Magpul with their 10 round Pmags for my G17 and G19, and my Glock 10 rounders for my G21 are good to go with no know operational issues with either ball or hollowpoints (other than reaquiring 2 man and a boy to load the 9th and 10th round, and you best not have to reload when the slide's in battery...).
My concern is with my Gen4 G22 (which I also have a Glock .357 SIG barrel for). I've observed issues with the Glock 10 rounders in a friend's Gen 3 G22, and in my most recent Armorer's recert we were advised not to use Glock 10-rounders for duty (that is, the Glock 10 rounders for the full-size and compact Glocks, not the smaller platform Glocks that use specifically designed 10 rounders). Has Glock provided any manifacturing improvements to the .40/.357 SIG 10 rounders that make them more trustworthy and viable?
I'm unaware of any credible other aftermarket 10 round magazines for the G22/G31...
Thioughts and recommendations?
Best, Jon
