Sig Sauer P365 Part 1

Sig Sauer P365 Part 1

Small Wonders

By Dennis Adler

The remarkable 9mm Sig Sauer P365 and CO2 model have a deep undercut triggerguard to allow more of your hand to grasp the shorter grip, and a large beavertail to protect the top of the shooting hand. Also note that the grip frame falls just short of aligning with the back of the slide, again moving the hand slightly further forward. As an example, compare that to the classic Walther PPK/S design, where the longer grip and angle of the grip extend past the vertical line with the beavertail, allowing the top of the shooter’s hand to be almost in line with the back of the slide. This is impossible with the P365’s design.

Sig Sauer has eclipsed all other American armsmakers, and yes Sig Sauer is an American armsmaker, (despite its European roots), building the majority of U.S. sold handguns and longarms in the United States, and supplying them to the U.S. military, federal agencies, and state and local law enforcement. They have also taken a significant share of the civilian arms market as well, and now with the P365, captured the attention of individuals with concealed carry permits, by building a micro-compact 9mm pistol with a 10+1 round capacity. Yes, there’s lots of small 9mm pocket models out there already, but not this small and not with a 10 +1 round capacity. It simply has not been done in a 9mm pistol this size. The P365 has won multiple awards including Guns &Ammo’s 2018 Handgun of the Year, and Shooting Illustrated Magazine’s 2019 Golden Bullseye winner for Handgun of the Year.

Other features worthy of note are that the striker-fired P365 has an elongated triggerguard for extra safety when engaging the trigger; it uses ambidextrous thumb safeties, and either a flat base magazine or finger extension magazine. The latter is used on the CO2 model. I have also not mentioned which of the first two pictures is the 9mm pistol. Anyone?

What is even more important to readers of Airgun Experience is that Sig Sauer’s SIG AIR Division has once again developed and released a matching CO2 model for training and sport shooting in .177 caliber at almost the exact same time. Sig Sauer did this twice last year with the WE THE PEOPLE 1911 and P320/M17. No other airgun manufacturer has ever reacted to the market like Sig Sauer, and with groundbreaking new technology at the same time.

Sig Sauer CO2 models have distinct packaging that caters to the retailer’s need to hang them on display racks several guns deep. This is great point of purchase marketing for air pistols. Usually this means a disposable (because you destroy it when opening it) blister pack. But not Sig Sauer’s packaging.

Un-boxing the P365

Price point all too often dictates packaging, and even with $100 plus CO2 pistols, manufacturers have resorted to blister packs better suited to mass marketing through big box chains, despite the preferences of airgun enthusiasts and collectors for reusable packaging. Sig Sauer has maintained its ability to accomplish both with its distinctive (albeit somewhat slow to open) packaging that serves the needs of retail display as well as consumers who want a solid, reusable package for storing the gun. The P365 has a surprising MSRP of only $99.99 which means it will sell discounted for as little as $79.95. That’s right smack in the middle of blister pack world. Since this is the smallest CO2 model (and 9mm model) that Sig Sauer has ever made, they have scaled down the packaging for the P365 blowback action pistol to fit the size of the gun, but still provide the host packaging as a suitable storage box for the P365 and accessories.

Open the top of the box, slip out the two-piece form fit molded clear plastic case, pull the top lid off and you have the gun in its own enclosed, dust free recess. The same design used for larger models like the WE THE PEOPLE 1911 and P320/M17 is scaled down to fit the small pocket pistol.

Sizing up the CO2 P365

We are going to begin, not by measuring the P365 against its 9mm counterpart, and believe me it measures up exactly, but rather against other current subcompact, blowback action CO2 models. And this is where the “Small Wonders” part of this story begins.

Nothing explains a new CO2 design like comparisons with popular older designs like the classic Walter PPK/S (based on the .380 ACP model) and PPS (based on the subcompact 9mm model). The P365 looks like it’s about the same size, but that’s because it is in front of the other two. In reality, it is much smaller than PPK/S.

If we compare two of the smallest blowback action CO2 pistols available, the Umarex Walther PPK/S and Walther PPS, whose centerfire counterparts are well recognized as subcompact pocket pistols suitable for concealed carry use, they measure up as larger guns than the new Sig Sauer P365. The PPK/S CO2 model is 6.06 inches long, 1.125 inches wide (at its widest point) and 5.0 inches tall. The PPS measures 6.25 x 0.95 x 5.0 inches.

As you can see in the overhead shot, the P365 is shorter than either of the other two CO2 models, which are also closely scaled to their centerfire counterparts. But more important than size, is the fact that the larger PPK/S and PPS use stick magazines while the smaller P365 has a 12-shot self-contained CO2 BB magazine.

The P365 is only 5.75 inches in overall length, 1.0 inches wide (at its widest point) and 4.5 inches tall with the finger extension magazine used for the 9mm model. Even with the finger extension, the P365 beats the PPK/S and PPS CO2 models by half an inch. And the Sig uses a self-contained, 12-shot CO2 BB magazine, while the larger guns rely on a separate CO2 cartridge in the grip frame and stick magazines! Yes, it can be done. A pocket pistol can be that small in its centerfire configuration and also as a CO2 model. Sig figured it out.

It’s a masterpiece of magazine design like its 9mm counterpart that manages to squeeze 10 rounds into a narrow grip frame that traditionally holds a single stack magazine. The P365 is a double stack and that translates into making a groundbreaking CO2 BB magazine

In Part 2 we will explore how Sig Sauer has managed to do what no other manufacturer has done (and that goes for 9mm subcompacts, too, by the way) with the P365.

A word about safety

Blowback action airguns provide the look, feel and operation of their cartridge-firing counterparts and this is one reason why they have become so popular. Airguns in general all look like guns, blowback action models more so, and it is important to remember that the vast majority of people can’t tell an airgun from a cartridge gun. Never brandish an airgun in public. Always, and I can never stress this enough, always treat an airgun as you would a cartridge gun. The same manual of operation and safety should always apply.

5 thoughts on “Sig Sauer P365 Part 1”

  1. The Sig in both firearms and c02 incarnation is an engineering marvel. If it can last as long as say a PPK, it will be the nail in the coffin for pistols like Walther. Lighter , locked breech, throwing a harder hitting round and holding almost double the payload. With extended mag the 9 mm can hold 12. The Sig 9mm has it over the .380. A bad sign will be a future James Bond trading in his PPK for the little Sig. In the airgun world Sig has thrown down the gauntlet to other manufacturers, if you want to be big, get small.

    • I totally agree. I just don’t know if Umarex feels the market for the PPK CO2 model is worth the expense. Although, it should be, since Umarex took the time and expense to update the PPS to the PPS M2 version. Just a question of whether they want to do it.

      • If Sig can make a pistol the size of the 365 with a co2 mag,Umarex should be able to make a true Ppk not bloated elongated, underpowered, Ppk/s with stick mag. Umarex appears to have gotten lazy with replicas. With the exception of theGlock 17 and H&K USP not much innovative, especially in the Legends series pistols. Peacemaker, don’t even get me started
