SIG P320 OEM 30 Round Extended Magazines

[HCM]

SIG P320 shooters now have factory ‘stendos.

In all seriousness this may be useful to those running P320 based PDWs and PCC variants like those from B&T and CMMG which utilize P320 mags. The apparent option for an over-insertion sleeve is a positive.

Plus if your P320 fails, you can club a m#####f@@@er to death with it.

If it doesn't spontaneously disassemble, of course...

Do these cost double the already astronomical pricing for standard capacity mags?

[Dave Williams]

I really like the 21 round mags. Easy to load and seat. Hopefully these are as nice.

Everything is proceeding as I have foreseen:

What's interesting, Promag's long stick is ostensibly 2 rounds longer: 32 in Promag, 30 in SIG.

Promag is also dimensionally incorrect. They are noticeably fatter and do not fit into older Ruger adapters. The magazine hole had to be enlarged for them. But then they bump against overtravel stops and basically hard to lock in. I very much hope that these "factory" SIG magazines are made better than Promag. I put scare quotes around factory because as we all know SIG do not make their magazines. It's probably Checkmate or something.

Is there an over insertion sleeve for 21-round mags in compact grip modules?

[HeavyDuty]

Reminds me of how our more turned-on deputies would tuck a Glock fun stick under the dash “just in case.”

My wife ordered two, but then she is pretty Sig-centric, as evidenced by her 320 parts area.

I have six of them coming to put into my B&T. I'll be curious to see how reliably these will feed. Looking forward to putting them through the paces.

Going to get 4 to toss in my Spiritus chest rig I keep with my Flux Raider

Guilty. I always keep one or two of the big sticks in my carrier on an enforcement action if I am just rocking a pistol. Better to have and not need. One of the reasons I didn't transition over the the 320 my agency offers is bc I like my 'stendo mags. I will be picking up a couple.

The easy insertion of the 21rd mags spoiled me. Numerous failure to seat today on the range with Glock 17 w/ oem +2!

Is this with the slide closed or locked open?

[Dave Williams]

Closed.

[Thy.Will.Be.Done]

Closed.

Why is this considered an issue? Tactical reloads where you're swapping partially spent magazine for a fresh one?

[Dave Williams]

Sorry to stray off topic. This was on a Rogers range doing a one hand Tac load during a lull.
