Sig Sauer P365 Design Story - Additional Details

Good afternoon SigTalk! I learned of additional details regarding the P365 design story from Arik Levy's (Firearms Nation) details-packed interview of Mr. Phil Strader himself at Shot Show 2018. (LINK HERE) The interview is called, "The Questions Answered On the Sig P365". It's been out there for several months now, so no doubt many SigTalk members & readers have already watched this interview. I highly commend it and have summarized key points in text form below for your convenience.

In Arik's P365 interview you will find some interesting tidbits about the P365 design story not found in the concealedcarry.com interview, and in my previous post HERE Though several parts of this interview overlap with the more lengthy (30+ minutes!) concealedcarry.com interview (LINK HERE) and are therefore redundant, nevertheless these interviews compliment each other very well, and I found fresh value worth compiling and posting for the convienence of all those interested in the design and creation of the Sig Sauer P365.

Enjoy this Friday afternoon read!


Firearms Nation Interview at Shot Show 2018 (1/24/2018)

17:28 Video Length

(01:01) (Arik Levy) What was the reason for the P365 since you already have a 320 subcompact?
(01:10) (Phil Strader) The 320 subcompact is a small gun, but doesn't fall in line with what people call the pocket carry or micro compact pistol.
(01:20) Sig had the 938 and the 290, but the Glock 43 and the M&P Shield have held that market pretty tight. They're great guns, but Sig found a gap in that market.
(01:44) When Phil Strader came to Sig, they showed him the P365 project which they were working on and handed the project over to him. This was over two years ago. [As of interview date]
(01:55) Phil and his team saw a large hole at the high-end of the striker fired pocket pistol market.
(02:05) Phil has owned a M&P Shield, he currently owns a Glock 43 and a few Kahrs. These guns are super thin, compact, and are pretty accurate, but you wouldn't want to shoot them all day long.
(02:25) The first challenge Phil and his team faced was to develop a pistol that was very compact and concealable, (Even smaller than competition.) but that you could still shoot comfortably, even for 500 round extended range sessions.
(02:39) The second challenge was solving the capacity gap. Everything out in the market was either 6 rounds or 8 rounds. They wanted to carry at least 11 rounds in the gun.
(03:08) (Arik Levy) People want to know why the P365 is compared to the Glock 43. (Interviewer describes pain he feels after shooting a high round count through G43, and also the G43's lower capacity)
(04:12) (Arik Levy) What is the difference between the P365 and the Glock 26?
(04:14) (Phil Strader) the Glock 26 is larger in every aspect. The P365 has the same round count with the flush fit and pinky extension magazines.
(05:03) Every single dimension of the P365 is smaller than a Glock 43, except for the width, which is the same at 1", while the P365 is slightly lighter.
(06:01) Phil has carried different guns, he has a Glock 43 and has shot it a lot, a Kahr P9, a Shield, etc. - he says he's shot just about everything and you should shoot the P365 for yourself and then make your decisions.
(07:25) One thing that is the same between the Glock 43, the Shield, XDS-9 and LC9 is where the trigger is located in relation to the back of your hand. On the aforementioned competitor's models, you are pulling the trigger straight up and to the rear. So the trigger comes up at an angle (An angular trigger pull). But when you pull the P365 trigger, you are pulling it straight back into the web of your hand. There is no angular pull; and by pulling the trigger straight back the P365 feels better to shoot.
(08:12) The low recoil impulse on the P365 is something you have to experience to understand.
(08:28) The P365 was released the day before this interview.
(08:45) Phil said they will start ramping up production and making more and more P365s. He didn't think they'd be able to make enough of them, but they would keep up with demand as best as they could.
(09:07) One unique thing about the 12-round magazine is how the base pad fits. They have a few patents pending on the design of how the base pad works.
(09:15) It was a challenge to keep the base pad from sliding up and being kind of loose and not pleasant to hold.
(09:45) When the 12 round magazine is used, the added grip area softens the +P or even +P+ round's recoil and makes it so it isn't brutal because you are getting more hand on the gun.
(09:58) The overall height of the P365 (4.6") is actually the average height of the [then] industry standards in this size category (Glock 43, M&P Shield, XDS-9 and LC9).
(10:24) Trigger has a nice pull. Sig is not really advertising the pull weight as a spec, but when people take it out and weigh it they'll probably find it in the 6-7 lb range.
(10:36) The P365 locks to the rear and takes down the same way as a P320. That is the only similarity there is.
(10:44) The P365 is a totally redesigned from the ground up pistol.
(10:48) To give an idea of how much smaller the 365 is than the 320, the P365 with the flush fit magazine is significantly smaller than the P320 sub compact grip module by itself.
(11:05) Phil reckoned that Sig would take a hit for the $50 cost for a magazine, a decision which came from higher up. Phil said that he would personally do it because of the difference he has felt in the 12-round magazine.
(11:23) Sig will be putting displays in gun stores featuring all three magazines so that people can feel the difference.
(11:59) If the 12 round mags don't sell then Sig would make adjustments.
(12:22) The gun was developed from the magazine. Sig built the gun around it. Sig wanted a 1" wide gun, with a double stack magazine.
(12:43) They built the thinnest double-stack magazine they could and then narrowed the neck a little earlier than normal.
(12:48) Sig was able to not only get a thin magazine up top, but now when a round is chambered, the two rounds under the slide are stacked up one after the other. They are not angled.
(13:01) So the P365 has the benefit of the double-stack capacity, but the reliability of a single stack's "row" at the top of the magazine.
(13:13) Sig got lucky with the magazine. The magazine was designed by a "genius" Austrian engineer back at Sig.
(13:20) Sig sent off the magazines drawings engineered by the their rockstar Austrian engineer, the prototype mags that came back worked perfectly.
(13:28) Phil and his team loaded rounds into the prototype mags the first time wondering just how difficult the 10th round would go in, and found it was just as easy as the first.
(13:40) He noted that the magazine was produced so tight to spec that he could not fit an 11th round in the 10 round mag. It was not too tight or too loose, it was perfect.
(13:42) Phil's second thought was that the original prototype mag wouldn't last and work, but it did. The magazines are flawless.
(13:49) After the magazines turned out right, Phil and his team designed the smallest, most ergonomically correct pistol around the magazine.
(13:56) They turned springs around to make the pistol small.
(14:01) Sig is mim-ing (metal injection molding) the trigger group and machining it in house. He said this has never been done before.
(14:10) Phil and his team were able to make the trigger group (FCU) very small and intricate, turning springs on their side.
(14:13) This involved fore and aft engineering to ensure that the hand can get up even higher on the slide.
(14:22) There is a picture floating around social media (Found HERE; NOTE: this pic is not mine.) that shows the outlines of other in-class handguns overlaying the P365. The main thing there for Phil was how much higher the P365's trigger guard is compared to the competitor's.
(14:41) Strader is stoked about the P365 and couldn't wait to get one and carry it.
(14:48) There are three patent pendings on the mag itself.
(15:22) Phil likes the P320 subcompact, but with the flush fit 12-round magazine he can't fit his third finger on it.
(15:40) Phil said in an apples-to-apples comparison between the P320 subcompact and the P365 in terms of recoil, it's actually very similar. But he finds the P365 faster to recover on target.
(15:50) The P365 recoil impulse is snappier but faster back on target, while the P320 subcompact recoil is more of a muley kind of kick, and it porpuses a little bit.
(16:04) If Phil had a choice, he would carry the P365 with the 12 round mag.
(16:09) Phil thinks the P365 is going to canabalize a lot of Sig's P320 subcompact sales because the P365 is "incredibly" smaller, but with similar muzzle velocity. Furthermore, the P356 is accurate.
(16:22) Phil took four P365's out of the R&D line up, shot all four and averaged under 2" groups at 25-yards. He thought it was a fluke, so he repeated the test and got the same group sizes.
(16:40) The first thing you'll notice when you take the P365 apart is that the slide rides on the rail. There isn't a front section of rail and back section of rail. The trigger group has a continuous section of rail that goes all the way across.

Thank you for your hard work. That kind of typing, from someone else's thoughts, is tough for me to do. Word-for-word transcription is a PITA, IMHO. Heck, even typing my own thoughts is getting difficult. And I'm not getting any younger, either.
