Trigger Pull: Single action only trigger so you will need to rack the slide to cock the trigger and internal striker, after which the blowback operation will do this for you. When the pistol is unloaded, the trigger pull length is short and the trigger weight is fairly light. When you load the full size drop out magazine, the trigger pull weight increases significantly. This is because the inner barrel comes back and into the magazine when the trigger is pulled, allowing for a better seal between the barrel and magazine which increases power and CO2 efficiency. The drawback to this is more friction on the trigger when you pull it with a loaded magazine.

Accuracy: I shot 5 rounds through my chronograph and averaged 287 FPS with the fastest being 297 FPS and the lowest being 276 FPS. This was pretty close to Sig Sauer's 295 maximum FPS claim and right in line for a super short-barreled blowback BB pistol. In terms of accuracy, I was able to get a 2.5 inch 10 shot grouping with all but one shot hitting within 2 inches of each other. I did find the P365 shot a little low at 30 feet, but not a crazy amount. In terms of windage it was well centered, maybe just a hair to the right.

Build Quality: The Sig Sauer P365 BB Pistol has a metal and polymer build. The slide is metal along with part of the full size magazine, and several inner parts are also metal. The frame along with sections of the magazine are plastic. It’s hard to tell if the trigger, safeties, slide catch, and take down levers are metal but I believe they are with the mag release being plastic. The Sig Sauer P365 is not the heaviest airgun coming in at about .8lb but for its size it feels good. Fit and finish is good.

Realism: The Sig Sauer P365 CO2 Blowback BB Pistol is a replica of the real steel Sig Sauer P365, which is a 9mm striker-fired everyday carry compact pistol. It looks and feels the part, with most external mechanical working parts mimicking the real steel version. I wasn't able to easily field strip the pistol since the takedown lever seems to be only for show. One main difference between the airgun and real steel version is the polymer in the frame. I imagine this is because 9mm rounds pack some punch and a small polymer frame may not have been up to the job, which is not something to be concerned with in a CO2 version of the same pistol.

Pros:

  • One of the smallest airguns on the market with a full size drop out mag
  • Good overall replica of real steel P365 in terms of look and operation
  • Full Sig Sauer markings and licensing
  • Working ambidextrous safeties and slide catch release
  • Snappy blowback feel for realistic shooting experience
  • White and green dot front and rear sights
  • Recessed barrel opening and open ejection port for added realism
  • Warning instructions are super discreet!

Cons:

  • SAO trigger can get harder to pull when loaded up with BBs
  • Polymer frame unlike metal frame on real steel gun
  • Not easily field-strippable

Comments: The Sig Sauer P365 BB Pistol was a real show stopper at this years SHOT Show. I was amazed that Sig Sauer was able to actually figure out a way to fit a full size drop out magazine that holds both the CO2 and BBs in such a compact airgun. The Sig Sauer P365 is even smaller than the Walther PPK in many ways, so great work by Sig in figuring out how to engineer their new P365 BB Pistol. I also think the the BB pistol is a great replica of the real steel version in looks, feel, and function which is what we are all looking for when considering buying a new CO2 replica airgun. Overall, the gun is a nice shooter, it has a very fast and snappy blowback action and makes a kind of popping sound that’s louder than I expected. The SAO trigger when using good quality smooth 4.5mm steel BBs was decent, allowing me to concentrate on my shooting rather than struggle with the trigger. All in all, I really love this little air pistol. Sig Sauer did a great job bringing it to market and getting as much into the CO2 blowback BB pistol as they could considering its super compact size.
