Customer Comments & Questions

Customer Reviews

(5 out of 5) Good and Bad
by Don from Scott Depot, WV on May 10, 2018

Good - Sportsman's Outdoor Superstore provided fair pricing and super quick delivery. Good - p320 performed flawless using multiple types of ammo. Zero malfunctions of any type for 300 rounds.

Bad -The Romeo1 premounted on my gun quick working after approximately 100 rounds.

(5 out of 5) Great gun
by Don from Scott Depot, WV on May 14, 2018

I originally reviewed this gun after 300 rounds and the Romeo1 had quit working. Turns out it was my fault. I didn't torque the battery correctly.....My bad. Great gun, great sight, and Sportsnam's Outdoor shipping was fast.

(5 out of 5) Love it!
by Tyler from Daytona, FL on July 8, 2018

Cant say enough about it! My friends the ones who like to shoot, are jealous. Havent told them where I bought this. I want to be the only one with it! Bought a normal P320 RX last year, but traded it in. Never used the rear sight anyway. Nickel slide makes this stand out from all other 320 shooters. I love it!

(5 out of 5) Buy it!
by Aron from Indianapolis, IN on July 11, 2018

This is the first of 3 firearms I’ve purchased from SOSS in the last month and I absolutely love it. I shopped around for the Sig P320 RX for weeks before finding it here, and as soon as I saw the price I immediately jumped on it. The firearm arrived at my FFL in perfect NIB condition just as expected. Obviously I was impressed with SOSS...I bought two more guns from them.
