Brett, unfortunately they're out of stock everywhere. Did some reading and magazines for a sig p320 fit with little modification. The holes in the magazine that catch to hold it in place are in a different spot. So if you're comfortable going that route just Google" sig p320 mag fit sar9 " and there's videos of how to modify it. If you want actual factory magazines I'd also recommend contacting Sara USA at 1-833-727-4867 and hopefully they have some in stock. Sorry but hope this helps.

Brett, you will need the factory magazine. Alternate sources are here : https://gun.deals/search/apachesolr_search/sar9-10 ---- Cheers and stay safe!
