Sig P365 Q&A from Phil Strader


Phil Strader, of Sig Sauer, put out some frequently asked questions and answers for the P365. These seem to be recurring inquiries.

Hello all,
P365 production is still increasing as we continue to build capacity to meet incredible demand.  We have shipped tens of thousands of P365s with overwhelmingly positive responses not only from our commercial customers, but from law enforcement and professional end users around the world.  In my 25 years of law enforcement and industry experience, I have rarely seen this level of excitement and positive reception around any single firearm.  Although there have been a limited number of striker and trigger return spring issues with this new platform, our return rates for these two parts are still extremely low…approximately 0.25% combined, which we believe is below industry standards for any type of return.
The P365 has received an unprecedented amount of praise and activity both in social and traditional media.  However, in the age of the internet, readers are sometimes exposed to grossly inflated or even non-existent issues. To address some of these concerns, we have compiled the most prevalent questions we’re seeing online and in our customer service department.
Q:  Can I safely dry-fire my P365?
A:  Yes.  We’ve dry-fired thousands of repetitions on our test guns and production models with no failures.  It should always be recommended to use a snap-cap or similar device during dry-fire practice for any firearm, but it is not required.
Q:  Why does Sig Sauer use a MIM striker?
A:  Metal Injection Molding (MIM) is used for complicated metal parts that would be impossible or overly complicated to effectively machine.  MIM technology is used throughout the firearm industry to manufacture small parts, including strikers, hammers, sears, triggers, and most integral gun parts. Moreover, our strikers are made from S7 tooled steel to ensure maximum strength and endurance.
Q:  What is “primer drag” and does it cause striker breakages?
A:  No.  “Primer drag” is found on fired cases and is simply a drag mark slightly below the indent in the primer.  It is caused by the pistol barrel unlocking while the striker is returning back to its recessed position.  This is not uncommon, and happens in most striker-fired micro compact pistols due to the increased slide speed.  The protrusion of the striker tip during ignition is minimal and has no effect on the striker’s durability.
Q:  What are the chances of my striker breaking or trigger return spring coming off?
A:  Extremely small.  Currently, returns for strikers and trigger return springs account for 0.25% of all P365s shipped, combined.  Although these numbers are extremely low, Sig Sauer will continue to evaluate all of our firearms to ensure that they meet the most stringent standards we have set for ourselves and that you have come to expect.
Q:  If I install an aftermarket striker in my P365, will it void the warranty?
A:  Technically, installation of aftermarket parts voids the warranty.  However, Sig Sauer would most likely cover unrelated returns including, but not limited to, defective sights, out of the ordinary cosmetic wear, magazine issues, etc.  Examples of repairs that would not be warrantied would be those that could be traced to an affected part including, but not limited to, light primer strikes, pierced primers, primer flow, trigger reset problems, etc.
Internet banter would have our customers believe that striker and trigger return spring issues are widespread.  In reality, these returns are no greater than any other potential customer service return.  Our return rates continue to remain below industry standards as a whole, and we will continue to stand behind our product line.

    what is the difference between a P290 and the P365. I have the P290 and happy with it, can’t find any comparisons between the two

      Hi Charlie! Good question. There is a pretty sizable difference.

      The P290 is a DAO trigger but the P365 has a striker trigger mechanism. The result is that the trigger on the P365 is much shorter (length of pull) and the weight is reduced compared to the P290.

      The P365 has a double stack magazine versus the single stack of the P290. The P290 flush fit mag holds 6 rounds and the flush fit P365 mag holds 10 rounds. Extended on the P290 is 8rd and 12rd on the P365.

      I don’t have the specs in front of me for height and width but they are pretty darn close. The P290 is probably slightly thinner through the grip but not much on the slide.

      The majority of P365’s (all current shipping) have X-Ray 3 sights but the P290 has either contrast or SIGLite night sights.

    My 365 LIMA green laser is bright, has a fairly large green dot, and fits the pistol like it is molded to it. But the button protrudes so little (less than half of competitive product) that I can’t reliably activate or keep the laser on when shooting, unlike my other pistols. Any suggestions?

      Hi Roy,

      We recommend giving Sig a call. If you describe your issue to them, they can make a suggestion and may just replace the unit for you.
