Note that Sig Sauer recently made an inline design change to the grip shells and slide catch levers. Watch our video below for additional information. We cannot guarantee that you will receive one or the other due to Sig using the same part numbers for the old and new style grip shells, Caliber X-Change Kits, and P250 / P320 firearms.

Unlike any other pistol in its class, the P320 features a unique 5-point safety system, standard on all models:

- Striker Safety
- Disconnect Safety
- 3-point Take Down Safety System
- Takedown is prohibited without removal of magazine
- System prohibits takedown without slide locked to the rear
- Rotation of takedown lever allows disassembly without tools or trigger manipulation.

The unique modular design of the P320 offers the user the ultimate in flexibility to change calibers, sizes, and fit. Small, medium, and large complete polymer grip modules ensure comfortable and optimal fit for the widest range of hand sizes.

Specifications are subject to change.

Customer Reviews

P320 Compact .45 with Night Sights Great product!!! Great price!! Review by Sig Happy Customer
First things first, Thank you Osage for a great product for a excellent price! This P320 Compact .45 9+1 striker pistol is fantastic just like my 9mm too but now I have the Big brother 45 ACP striker! This compact package is "Just the right size" for ITW or OTW and has the rail too, this kit includes the 2 nine rd mags and holster. These product lines can be interchangeable with sub compact and carry too. I will probably purchase the grip in FDE also as it is just plain good looking. I got mine, now you go get yours as soon as possible, no regrets on this great deal from Osage!! (Posted on 10/25/2015)
