SIG P365 with 10 rd magazine with extended baseplate

The Sig Sauer P365 is an incredible gun design and packs about as much firepower as a pocket gun can have.  The first thing Sig did to develop the P365 was design the smallest possible magazine that could hold 10 rounds or 9mm.  They then designed the gun around magazine.   Having a polymer grip frame enabled the designers to make the gun barely thicker than the magazine.

To give an idea of the size, the specs below compare the P365 to the Sig P238 in size.

Measurement                    SIG P238            SIG P365               P365 Difference

Overall Length                       5.5”                   5.8”             0.3”            (5%)   Longer

Overall Height                       3.9”                   4.3”              0.4”         (10%)   Taller

Overall Weight                       1.1”                   1.0”             0.1”          (11%)   Narrower

Weight (Unloaded)               15.2 oz             17.8 oz          2.6 oz       (17%)   Heavier

So the P365 is only a little bit longer and taller and wieght less than 3 oz more.  Importantly for concealed carry it is actually a little bit narrow than a P238.   Yet, despite being only 0.3” longer than the P238, its barrel is 0.4” longer.  It also packs considerably more firepower in the slightly large package.  While the P238 is a .380” ACP, the P365 is a 9mm and is even +P rated.  The larger magazines result in around 60% more available rounds with each delivery around 50% more energy (90g .380 ACP vs 115g 9mm) when firing the Sig Sauer Elite V-Crown hollow point ammo designed for these guns.

Standard Capacity               6 + 1                10 + 1            4 rds        (57%)   More

Maximum Capacity             7 + 1                 12 + 1           5 rds        (63%)   More

Muzzle Energy*                192 ft/lbs           282 ft/lbs        90 ft/lbs  (47%)   More

Having all this 9mm firepower in a package barely larger than a .380 ACP pocket pistol is revolutionary.  It narrower shorter and only 0.05” taller than a single stack 9mm tGlock 43 but carries 4 to 6 more rounds of 9mm.  The P365 could have been even lighter, but Sig Sauer chose to go with a slide that is heavy enough to dampen the recoil and doesn’t require an overly stiff recoil spring.  Due to this it is easier to rack the slide back than almost any concealed carry handgun.  It also has an excellent trigger.   Finally, it comes with tritium night sights.

The P365 is a revolutionaly step in concealed carry handgun design.  It offers unprecedented firepower in a pocket carry sized hadgun.  Its major drawback is that it is so popular, it is very difficult to find.
