Let’s dive in!
Sig P365 XL
The Sig P365 XL is a popular concealed carry gun for a reason. First introduced in June 2019, the XL is similar to, though slightly larger than, Sig Sauer’s original P365.
The gun comes standard with a 12-round magazine, though an extended 15-round magazine is available as well. It also has a flat trigger and longer slide than the smaller P365.
The Sig P365 XL weighs only 20.7 oz., has a barrel length of 3.7” and an overall height of 4.8”. It has a stainless steel frame and a black polymer 365 XSeries grip module with an extended beavertail and integrated magwell.

Hellcat Pro OSP
Springfield Armory released the Hellcat Pro OSP on March 4, 2022. The pistol is similar to its predecessor, the incredibly popular Hellcat micro 9mm, with a few exciting upgrades.
The optics-ready Pro model comes with a longer grip and a longer hammer-forged barrel than the micro and comes standard with a flush 15-round magazine, a larger capacity out of the box than any other gun in its size and class.
Weighing only 21 oz., the striker-fired Hellcat Pro has a barrel length of 3.7” and a height of 4.8”. It has a black polymer frame with an adaptive grip texture and a dual captive recoil spring with a full-length guide rod.

Specifications of the Hellcat Pro OSP vs. Sig P365 XL
Capacity
Both gun models have an impressive capacity for a pistol of their size. Coming standard with a flush 15+1 magazine capacity, the Hellcat Pro OSP is designed to hold more rounds than any other gun model of its size and class.
While the P365 XL comes standard with the slightly lower magazine capacity of 12+1 out of the box, with a mag extension the Sig model can hold up to 15+1 as well.
While both guns can hold up to 15+1 rounds, the Hellcat Pro has a slight advantage in this area as its standard 15-round magazine is flush with the grip while the P365 XL’s mag extension adds around 1” to the overall grip length.
Ergonomics
Frame: Just 1.1” wide, the P365 XL is built with a stainless steel frame and a black polymer 365 XSeries grip module. The XSeries grip module comes with a slightly extended beavertail and an integrated magwell. The XL’s magwell fully encompasses the rear and sides of the grip, making it fairly easy to slap in a magazine. Its grip has a stippled texture on all four sides, which gives it a nice feel and makes it easy to get ahold of.
The Hellcat Pro has a black polymer frame with an adaptive grip texture. It also comes with a dual captive recoil spring and a full-length guide rod. The Pro also features a custom pressure-activated grip texture with a staggered pyramid pattern designed to increase the user’s contact and control. The taller pyramids in the pattern are designed with flattened tops to make the pistol more comfortable in your waistband and to reduce wear on clothes. The shorter pyramids come to a point so the gun effectively locks into your hand when it's firmly gripped.
Slide: The Hellcat Pro’s slide features front and top serrations in addition to its rear slide serrations, allowing for positive purchase and reliable manipulation. Extra mass and weight in the slide and barrel allow for a reduced muzzle slip, resulting in faster follow-up shots. The XL’s stainless steel slide is extended and features both front and rear serrations.
Both firearms have protective finishes on their slide and barrel. The Hellcat Pro OSP is finished with Melonite for added toughness while the XL’s slide is finished with Nitron, an extremely durable compound.
Barrel: The barrel on both the Hellcat Pro and P365 XL measures 3.7”. The Pro’s barrel is made from hammer-forged steel while the XL’s barrel is made from carbon steel.
Sights
When it comes to Hellcat Pro OSP vs. Sig P365 XL, both come with sights that allow for daytime target acquisition as well as shooting in low-light conditions.
The Pro features a high-visibility tritium and luminescent front sight along with a Tactical Rack U-Dot™ rear sight. The U-Dot is designed with luminescent green rings around the tritium dot, giving the shooter large, visible sights for aiming in low-light conditions.
The XL comes standard with its signature X-RAY3 day and night sights, which are also designed for day and night shooting. The 3-dot system is designed with steel around the tritium sights to protect them from both the elements and recoil.
Optics
Both the Hellcat Pro and the P365 XL come optics ready and are designed to be used with red dot sights. The Pro comes equipped with a slide milled into the Springfield Micro™ footprint, making it compatible with some of the smallest micro red dot sights on the market today.
The XL is built with a plate assembly, allowing you to directly mount micro red dot sights like Sig Sauer’s RomeoZero or RMSc reflex optics.
Controls
Controls like trigger design and safety are some areas in which the Hellcat Pro OSP and the P365 XL are pretty different. Both firearms offer objectively good control designs, so it really comes down to personal preference when choosing between the two.
Trigger: The P365 XL comes with an XSeriesStraight trigger, Sig Sauer’s signature flat profile trigger. It has a slight hook at the bottom and rounded edges without any sharp corners for a comfortable pull.
The Hellcat Pro comes standard with Springfield Armory’s new Gen 3 trigger, which is designed to be relatively flat for the comfort aspect. It is also designed to have a fairly firm trigger pull.
Safety: While the XL is available either with or without a manual safety, the Hellcat Pro is not offered with any sort of manual safety option. The Pro does come with a trigger safety, however, while the XL does not. Both firearms have a striker pin safety and come with a loaded chamber indicator so you can safely and easily determine the status of your gun.
