Great pistol with red dot Review by Mark
Several local stores have been told by Sig to increase their price on the P320RX. So this price is really competitive.
Easy working with RK Guns. Just had it shipped to my local store so no FFL transfer charge to add to the price.
BTW - a great pistol, the red dot was slightly off but with older eyes I was hitting bulls eyes at 7, 10, and 15 yards. I had to get used to using the red dot but now I pick it up immediately after practicing at the range on 4 different trips. (Posted on 8/18/2017)

Great Gun Review by Kyle
First day at the range I was shooting the dot out at 25yds. after making minor adjustments I also have the 320c for daily carry Great Guns at a Great Price from Rural King (Posted on 5/29/2017)
Great Gun! Review by J Long
I purchased the P320c RX and I couldn't be any happier. To get this same gun optic ready, you'll be in well over $1000 by the time you're finished. The Sig P320 is about $500 with tax, the Romeo 1 is 299.99 at the cheapest, paying someone to mill your slide to accept the sight is no cheaper than $150, Sig's suppressor sights are around $90-100. Do the math. This is a smart buy if you're looking for a fun, accurate, and modular pistol. (Posted on 5/16/2017)
It's a SIG! Review by Bullshooter
Not too much to say . It's a Sig!. the name alone indicates a quality fire arm .

RK guns was a pleasure to deal with . Answered all of my questions promptly and explained their particular ordering and shipping process . (Posted on 4/11/2017)
Great gun Review by Retired cop
My 9th Sig including the three I carried on duty have one P225 with over 60,000 rounds that IO still shoot and qualify with. The new p320 seems to be of the same quality and precision. You can't beat a Sig for dependability. I look forward to 60,000 or more with this one. If you can find one I highly recommend it. (Posted on 4/9/2017)
Great gun! rk guns price too high. Review by Butkus
Transaction was smooth and typical Sig quality. The Rx version was sold out every place I checked but when in stock you can get them $80-100 cheaper than rk guns. Still a good value considering what you get. (Posted on 4/2/2017)
