Sig had them in stock and shipped right away. Also gave me a 25% discount for a future purchase. I love how the firearm feels in my hands and shoots great! I also own the P320 full size. It's my favorite gun for the range. Personally, I like having the safety and want to use it eventually as my edc (P365 now). No issues and I love the larger capacity mags for the range. 9/17/2020 ** ** ** ** ** ## Don't Forget Your Ammo ```json {"@context":"https://schema.org","@graph":[{"@id":"https://www.kygunco.com/#website","@type":"WebSite","description":"Shop KYGUNCO for firearms, ammo, accessories, parts, and outdoor gear at low prices with fast, easy nationwide shipping.","name":"KYGUNCO","url":"https://www.kygunco.com/","publisher":{"@id":"https://www.kygunco.com/#/schema/organization/kygunco"}},{"@id":"https://www.kygunco.com/product/sig-sauer-320ca-9-m18-ms-p320-m18-carry-9mm-3.9-coyote-17-21rd#webpage","@type":"WebPage","description":"Sig Sauer P320 M18 Carry 9mm Semi-Automatic Pistol w/ Night Sights & Optic Ready - Coyote Tan.
