It’s finally here, the weapon that might just sweep all before it and take the crown for the best concealed carry handgun in the world. This is the Sig Sauer P365 Nitron.
This 9mm carry pistol is beyond compact, in fact it’s 5.8 inches in total and yet it’s so much smaller than the immediate competition in almost every dimension.
Capacity is King With Carry Pistols
Somehow, you get 10 rounds plus one without resorting to an extended magazine. The bigger mag offers 12+1 rounds. That really is nibbling on the heels of another one of our favorite striker-fired 9mm CCW: the Springfield Armory XD MOD 2.
We love that gun for the sheer capacity of the double-stack magazine. It’s a snappy and yet surprisingly accurate pistol that’s easy to hit groups with at the range.
The Austro-American outfit went the same route with a double-stack mag, but went for an even smaller gun that is just 1 inch wide at the controls.
P365 Feels Right Out the Box
Everything is just right, too, from the long trigger with a positive reset right through to the slide work and stippling. This isn’t a gun you’ve got to build up yourself. Everything just works, right out the box.
You can modify your P365 with everything from a custom slide to a flat face trigger and we have some ideas for your custom Sig P365 here.
You get Tritium night sights and you can upgrade those with a laser-pointer, but they add bulk to a remarkably lightweight gun that weighs just 1.11lb
This is one of those instinctively ‘right’ handguns.
Micro-Compact 9mm With Compact 9mm Capacity
Sig is calling it a micro-compact with a high capacity and it’s hard to argue with their reasoning. It’s also an elegant gun, a pretty gun. For a concealed EDC, that can be a good thing.
You get the legendary reliability and even a little brand cache with Sig. They don’t make cheap guns, but they do make great ones. Hey have torture tested this new concealed carry gun to death and it’s a tough polymer weapon that should comfortably match up to the Glock 19 in terms of reliability.
This weapon really has the potential to disrupt the CCW pecking order and we think a lot of M&P Shield, Glock 43 and, yes, Springfield Armory fans might be tempted to make the switch.
It’s a good price on Brownells right now. So if you know you want to buy a Sig Sauer P365 Nitron, then put in your order and buy a big box of 9mm ammo with the savings.
