They are widely used because of their micro-compact concealability with full-size shootability. Compared to the P365 series, they make your shooting experience more comfortable and versatile.

Plus, it reduces the trigger travel, allowing you to quickly respond in tactical situations. Along with the trigger, this kit includes some necessary items that enable you to install the part smoothly.

Lights allow you to have a clear visibility of the targets. Unlike other optics, they don’t work to make aim on the targets, rather they help you to spot your target.
Now I recommend Streamlight TLR-7 because it features a 500 lumen output system. Thus, it will be able to deliver a powerful beam with extensive range and good peripheral coverage.
Besides, it has other user-friendly features, enabling it to have a smooth operation system. The light has a lightweight and compact construction, making sure that it doesn’t take up much space or add extra weight to your firearm.
Moreover, to run the light, you will get Lithium batteries with the product. Plus, the company offers a 2-year limited warranty along with the optic.
ii) HOLOSUN HS507K-X2 Classic Multi Reticle Red Dot Sight
Whether you’re under bright light condition or low light condition, red dots always have got your back. So, if you mostly use your firearm in daylight or low light, red dots will be a great choice for you. For your P365 XL, I believe HOLOSUN HS507K is a wholesome red dot that you can consider.
It is equipped with advanced technologies like Shake Awake and Multiple Reticle System. These systems enable you to shoot on the target in all shooting environments. Plus, it includes a super LED high capacity lithium battery which can power up the red dot up to 50,000 hours of its battery life.
Additionally, it has durable construction and multilayer lens coatings, allowing you to use the optic in bumpy and low light situations.
However, if you want you can also check out another red dot from HOLOSUN which is “HOLOSUN HS407K-X2 Classic Reflex Red Dot Only Sight”. To mount this red dot you will need an adapter. So, you can choose the “OuterImpact Red Dot Adapter Mount for Sig Sauer P365” to install the red dot on your P365 XL.
Oh, wait! Before moving on to the next upgrade, I would suggest you purchase a holster when you’ve upgraded your firearm with optics. Holsters are important to keep your gun and optic intact from the outer harmful elements. So, choose the “CrossBreed SuperTuck Deluxe Holster” if you’re looking for a good quality holster.
4. Sig P365 Xl Grips Upgrade

This grip is so popular that it is preferred by law enforcement officers, military personnel, competitive shooters, and also firearms enthusiasts. Given its quality, the NTOA has rated the grip 4.81 out of 5.
It helps to improve your performance with better traction and reduced recoil.

In order to make accurate shots, muzzle devices come in very handy. Muzzle devices such as the compensators work great to reduce the muzzle rise and make the perfect shot on the target. Other devices like suppressors enable you to mitigate the shooting noise of the firearm.
i) Silencerco Osprey 45 Suppressor
The suppressor works great to reduce the sound of the bullet shots. One of the main reasons for its wide use is its meticulous and user-friendly design. The Osprey .45 suppressor is known to be an eccentric silencer, meaning the bore of the part does not run down the middle of the tube.
As a result, most of the baffles and internal volume are beneath the centerline of the bore and out of the way of the gun’s sights.
In fact, the suppressor has nearly 30% more internal volume than a traditional round tube silencer at the same length. So, the shooters get the ability to aim with little to no sight obstruction on the target.
ii) Herrington Arms Sig P365 & P365XL HC365 Compensator
The device has been crafted to mitigate the vertical and horizontal recoil of your P365 XL. Hence, if you want to make follow-up shots on the target, the compensator works perfectly to reduce the muzzle climb.

Due to this construction, the magazine can perform its best when you shoot on the targets. Note that, apart from the 50 capacity, the magazine is also available with the 30 capacity. So, you can purchase the magazine at your desired capacity.
