These are the newer-style Sig P320 mags. They were made in Italy, just like the ones I got straight from Sig. Osage shipped these within 10 hours of ordering and they arrived a couple days later. Review by RL (Posted on 12/24/2020)

This a great item and the price only makes it better. I love the 21 round mags because they fit so well and I did not have to add a extension to them. Great item did I say that yet!
Thanks, and they arrived really fast for it being so close to Christmas.

Well everyone Thanks and have a great Christmas or holiday whatever! Review by Bass lane (Posted on 12/20/2020)

Many vendors to choose from, and several are truly terrific. This is an endorsement for Osage which places them at the top of that list. Really. Top. I'd go out of my way to buy stuff from them simply due to my experience. Now if they just had some 9 at 20 cents a round like this time last year..... Review by new Osage fan (Posted on 12/17/2020)

Excellent buy. Genuine new Sig Magazine in original packaging. 21rd mag works nice in the gun, looks good for an extended mag and doesn't stick out to an extreme degree. Fast shipping. Best price. Review by Paul (Posted on 12/16/2020)

21 Round Sig Mags

Quality

Value

I purchased the Sig mags on sale for 39.99 over the 2020 Thanksgiving holidays. No qualms whatsoever bout the mags themselves.
But they weren't shipped in a protected box but rather a Fed Ex envelope. Causing damage to the Sig factory packaging. And the packaging for the mags were damaged and one mag had scuff marks on it, from what it looks like a heavier box was placed on top of the envelope. Scuffing only matters if one was reselling, which I'm not. Just an honest review from my perspective. Review by Ronald (Posted on 12/4/2020)

This magazine is well made in Italy! My 17rd magazines that came with X-Carry were made in US. And unfortunately, I encounter some resistance/grinding when I need to remove the bullet from the magazines to change the bullet types (training vs defensive). However, with this 21rd magazine the bullet removal is butter smooth. Review by Zorik (Posted on 10/16/2020)

OsageGuns Nails it AGAIN!

Osage County Gun is the Absolute best Sig Sauer Dealer! Shipping is always blazing fast, products exactly as ordered and always arrive ahead of estimated delivery time. Unfortunately the carrier completely destroyed the packaging and scratched up the mags, but it was not Osage Guns fault. These 21 round mags are fantastic! They feed reliably every time. I use them in all my sig P320's and my CMMG MK17 Banshee. They are perfect size and fit perfect. Not to mention Osage Gun pricing always blows all the competition away every order.
