The Sig Sauer P365 has been an absolute game changer in terms of concealed carry. They revolutionized the thought of carrying a gun when they crammed 10+ rounds of 9mm into a small, single stack sized frame and called it done. Since its release other companies have released their version of a high capacity micro compact but there will only ever be one Sig P365.
Since it has been out for a while there is a literal ton of aftermarket support for this gun. Navigating your way around this mess if you’re in the market to take your pistol to the next level can be a daunting task, so I thought I’d put together the list of things I plan to buy for my own P365 once money is no longer an issue for me.
What are the best SIG P365 Accessories?
While the SIG P365 is a great carry gun that has received industry wide praise for concealed carry, there are a few improvements that should be made that will make the gun even better. Chief among these improvements is changing the thickness of the grip to allow for a better purchase on the gun itself while shooting. Other accessories that are suitable for inclusion into this list is a weapon mounted light and giving the gun even higher capacity than it comes with from the factory.
Sig P365 Grip
One of the most popular aftermarket accessories for the p365 actually arises out of a need where the gun actually falls short. This pistol, while an excellent carry option for concealment purposes, does come at the cost of a very small grip. For some people, me included, the grip is actually too thin, and not beefy enough.
Because of this, I recommend that EVERYONE who owns a SIG P365 buy this or a similar grip. I will say that this is the number one selling 365-specific grip on Amazon for a reason and you will not regret it. The stock grip is just too thin and a grip like this will allow you to get a better purchase on your gun when you’re shooting it.
You won’t regret it.
Sig P365 Light
This next one fills another void with a factory gun. So, one thing that I thought was a real bonehead move on Sig Sauer’s part was the accessory rail. Their accessory rail will only fit lights and attachments that’ll fit on this proprietary rail. What this means, is that you cannot buy a PL-Mini2 from O-Light and install it on your P365.
It’s proprietary and only a few manufacturers make lights for this particular rail.
There are some weapon mounted lights (WML) that will fit, but they’re usually made by SIG and aren’t very bright. This one, for example, is a real turd. However, there is an attachment that will turn the SIG proprietary rail with nearly zero accessories available, into a picatinny rail that enables you to put whatever you want, from whatever brand you want.
You can buy them right here on Amazon, and are well worth the price.
And again, I recommend the OLIGHT PL-MINI 2 Valkyrie (Amazon link), which is 600 lumens, and a good, small size for your small concealment pistol.
NOTE — The above setup will seriously limit the number of holsters you can carry this gun in. Hence the bonehead move by SIG. If you want more holster options, you must opt for a dimmer light, like the above linked one made by SIG themselves, or a TLR-6 made by Streamlight (Brownells link).
That TLR-6 is still only 100 lumens, and not very bright, but if you require a holster and can’t have one custom made, this is about your only option to have a WML. As a bonus, the TLR-6 doubles as a laser if you’re looking for one of them.
Sig P365 Holster
If you’re planning to carry your P365, and why else would you have one, you’re going to need a holster for it. We’ve already covered the best SIG P365 holsters in great detail in this article. However, I do speak very highly of the Concealment Express IWB, and it’s the #1 best selling holster with over 13,000 ratings on Amazon. Not only do I own one for one of my SIGs, they get great reviews by other folks, too.
SIG P365 Extended Mag
If you’re going to carry this gun for personal protection, we recommend carrying it with the 10 round mag for optimal concealment, with an extra magazine elsewhere on your body to maximize your effectiveness and round count.
Gun Mag Warehouse sells both the 12-round magazines and the 15-round magazines and they’re in stock a lot more often than other places where they’re constantly selling out (this is not a guarantee that they’ll be in stock, this is a popular accessory).
SIG P365 XL
Okay, this is kind of cheating, but I actually prefer the 365 XL to the original model and is the one I opted to buy. I strongly recommend this as an upgrade to your pistol, because it is better in every aspect. You can read my review on the 365 XL here on our website.
The SIG Sauer P365 is a real game changer, and even created a new category of pistol in the concealed carry market. That new category is being called high capacity micro compact, and there is no going back. I hope this helped you on your journey in deciding the best SIG p365 accessories that you can buy right now.
