(5 out of 5) Nice Gun
by George from Williamstown, NJ on November 20, 2017

I love my Sig P320 it shoots accurately feels good in my hand. I shot hundreds of rounds not one problem or jam & easy to clean. SOSS has great prices and excellent service, this is my second gun from them and will be more to come.

(5 out of 5) Very nice pistol
by Vaughn from Strasburg, VA on September 17, 2018

This P320 Compact is a very easy to shoot well gun. Very easy to take down and clean. I haven't shot thousands of rounds through it yet but so far it has been flawless with no problems. I have a Glock 19 and a M&P9 Compact 2.0, both which are comparable and all three are great guns. The P320 comes with two mags, night sights, a pretty good holster and plastic case for $439.99.

Along with free shipping and no tax it seems like a good deal to me. I have purchased 9 pistols, 1rifle and some magazines over the last six years and have had nothing but good service from SOSS.

(5 out of 5) Great: price`;` service`;` gun
by Peter from OOSTBURG, WI on December 20, 2018

SOSS priced less than everywhere I checked online and brick/mortar...can't beat the prices here! Service was flawless...shipped out quickly and arrived at my FFL with no problems. Just a really smooth process. Never ordered a gun online before...this experience was painless and so easy.
 Now on to the show.......the SIG P320 is the real deal. Just cleaned off the factory grease first night and next night headed to the local range. Banged out 90 rounds to just test it out...wow, this gun is nice. Have compact size...recoil is hardly noticeable for me. Just felt really good, smooth, and accurate just using the sights. The fact this model is modular allowing me to swap out the frame for a carry size made this an easy choice...compact for the range, and carry frame another $40 only for CCW...sweet deal SOSS....THANKS!
