    Awesome firearm, fast shipping!

    Posted by Josh H on Aug 29th 2018

    I ordered from impact on a thursday afternoon and the firearm was picked up by fed ex the same day, it made it to my local ffl four days later (MI) however had my ffl been open on the weekends i would have got it in three days! I was thrilled to see such fast and friendly customer service and i would not hesitate to order from Impact again. My one and only complaint is that my new firearm did not come with a owners manual or any of the typical Sig paperwork. This is really a non issue as i contacted Sig and they have a book in the mail for me. Thank you Impact for the fast and friendly service!

    Great firearm

    Great firearm. Accurate and reliable but would not expect anything less from a Sig. Just wish it came with two mags. But you won't be disappointed shooting it.

    Sig has a great reputation which is well deserved(226 is still the best) and this firearm is no exception. I want to get it in 45 now as well. Enjoyed a morning of range time with the gun. Accurate, easy to getback on target, nice trigger and sites. It only came with one magazine. That is the only thing I would change, add a second. Well worth money.

    P320 9mm Full is a solid purchase.

    Posted by Ray on Jun 7th 2016

    I wanted to buy a Beretta M9. I went to Impact Guns on 285 West 2100 South, South Salt Lake City. I indicated that after a bad customer experience at Cabela?s in Lehi. I decided to check out Impact Guns. The customer service at Impact was great, not only did they show me some alternative choices in the 9MM category but I ended up purchasing a Sig Sauer P320, for $20 less then I would have paid for the Beretta I intended on purchasing. The background check went quickly, compared to Cabela?s older and less customer friendly software. I will definitely be coming back to Impact Guns for my future gun purchases. Two days later I took this weapon to the range, and I?m not disappointed. This weapon fired flawlessly, and was very comfortable in my hands. The trigger has an easy pull and consistent every time. No problems, I?m very happy with this purchase. I wouldn?t expect anything less from a Sig.
