Sig P365 XL Review, Hands-On [+ Video]

Gun University was invited up to Sig for a special day just so we could check out the Sig Sauer P365 XL a couple of months before it was released. In this Sig P365 XL review, we’ll be covering what we thought of the P365 XL, how it compares to the earlier models, and the pros/cons and specifications of the Sig P365 XL.

[Update] I originally reviewed this gun in 2021, but recently I had the opportunity to lay my hands on it again and shoot a couple of hundred rounds. This experience has changed my thoughts on it, so I’ve updated my review accordingly. So, let’s dive into this updated review and see what’s changed.

SIG P365 XL BACKGROUND

The standard P365 was reliable, accurate, and comfortable to shoot. Most importantly, it could hold a 12-round magazine while staying as compact as competitors’ models that only held half as many rounds of 9mm.

Magazine Capacity

One of the major features of the Sig P365 over its competitors is its capacity, most people we know who carry them (ourselves included), choose to carry their P365 with the extended 12-round magazine.

Sig’s extended 12-round magazine for the P365 is nice in that it really improves the grip – it isn’t just an afterthought. However, there are two potential issues with it for some shooters:

The 12-round extended magazine is part of the grip. Therefore, when conducting a magazine change, the shooter’s hand must release part of the grip.

The extended 12-round P365 magazine is an additional purchase on top of the cost of the P365.

Sure, having part of the grip be the magazine can be a benefit when the shooter wants the option to use the smaller magazines for a smaller pistol. However, as we mentioned above, most shooters use only the 12-round magazines.

Accuracy

As a former special operations sniper, I can attest to the phenomenal accuracy of the P365. Check out our Sig P365 review for some proof. However, for some shooters, the short sight radius made it difficult for them to achieve the accuracy potential of the platform.

Sig’s answer? The Sig P365 XL.

The P365 XL offers a full-length grip that accepts flush-fit 12-round magazines that come with the pistol and a long slide for an improved sight radius (and an increase in velocity). It also can accept extended 15-round magazines and comes standard with a flat x-series trigger. Also, with new micro red dots for these smaller CCW pistols, Sig sends the P365 XL already milled for an optic!

More on this below.

Sig P365 XL Review – Our Take

Gun University was invited up to the Sig Academy to try out some of their newest products – it was awesome and we’re really excited about these two new pistols from Sig (as well as other products we got to play with that haven’t been announced yet).

Range days with a manufacturer to try out their new products are always fun but they are almost always part of a “media day” where there are lot of other folks lining up to shoot the products too. Unfortunately, it can be difficult to really get some time with a gun in this format.

We were insanely lucky in that Sig hosted the day at the range with their product managers and crew just for us! This gave us a TON of time with each product to really put them through their paces and get a solid feel for what each one offered.

Our hands-on experience with the P365 XL a couple of months ago gives us this review. If you’re not already familiar with the P365, you might want to start with our P365 review as the P365 XL is a variation of the P365.

Sig P365XL Grip

We absolutely LOVE the grip of the P365 XL!!! 

We thought we liked the P365’s grip until we tried the P365 XL’s grip. Seriously, if we could have taken the grip module from the P365 XL that we were testing and taken it home to put on our P365, we would have.

The grip is just the right size to give you a great purchase on the pistol while still being small enough to carry concealed. It is equivalent to the Glock 43X in length.

One potential downside for some shooters: If you like the ability to have the smallest pistol possible, then you may not like the P365 XL because it forces you to have the same grip length as the extended standard P365 – you can’t go shorter. If this is you, you might want the standard P365 instead.

However, if you’re like us, we only run with the extended 12-round magazine on our P365s so it just makes sense to have a full grip that doesn’t go away during magazine changes. Also, the grip length requires the P365 XL to come with 12-round magazines as standard – no need to buy extra mags.

Even better news? The P365XL has extended 15-round magazines!

Sig P365 XL Slide

The longer slide of the P365 XL doesn’t really do it for us but we realize that it is desirable for many shooters.

The idea of a longer slide is to provide a longer sight radius (distance between the sights) and a bit more bullet velocity for more energy.

We get it – both of those are things we’d like too! However, they come at a cost (albeit a small one)…. the longer pistol is harder (slightly) to conceal… especially when carrying in the appendix position.

As for the slide serrations, while they do offer a decent grip for slide manipulation, they don’t stand out as particularly remarkable. They’re functional, but nothing to write home about.

Is it a deal breaker? Absolutely not! In fact, if this pistol came out first and we didn’t know that another model had a shorter slide, we’d still love the P365 XL. All we’re saying is that the longer slide length isn’t a benefit for us (it’s not really a detriment either).

P365 XL Trigger

The trigger on the P365 is great… the trigger on the P365 XL is greater.

The triggers on our P365 XL are so great (especially when compared to any competitors) that we’ve never really needed to upgrade them. However, now that we’ve tried the x-series flat faced trigger on the P 365XL we kinda’ wish our standard P365s had this new flat trigger too.

The trigger guard on the P365 XL is also nicely shaped, providing ample room for easy manipulation, even with gloved hands.

P365 XL Optics Cut

WAY TO GO SIG!!!

Red dot optics are the way of the future – we are happy to see manufacturers adopting them.

The Shield RMSc is made for compact pistols and many people have already been sending their P365s off to get milled for the micro red dots. Thankfully, the P365 XL comes milled from the factory!!!

One minor criticism? The rear iron sights are part of the plate that must be removed to install a red dot. If you’re using a Shield RMSc, this isn’t a problem because it has a built-in rear sight. However, other manufacturers do not have built-in iron sights – if your red dot goes down, you could be missing backup sights if needed.

P365 XL Summary

If you’re looking for the smallest pistol to have the option to hold up to 12 rounds, get the standard P365. However, if you want a pistol that is slightly larger, you’d like an optic cut from the factory, has a 12 round capacity standard, and is a bit more shootable/useable, the Sig P365 XL might just be for you! We’d be happy with either one.

Also, the Sig P365 XL is a really nice fit between a sub-compact and a compact handgun– it is big enough (especially with the 15-round extended magazines) to handle full size jobs and is small enough for concealed carry.

What would we do differently? We’d keep everything except the longer slide. The new grip, the optic cut, and the upgraded trigger are all obvious upgrades for us. The longer slide is merely a feature change – it’s up to you whether it is a benefit to you.

If you can only afford, or you see the benefit in training with, only one handgun, the Sig P365 XL should be it! It is big enough (especially with the 15 round magazines) to be a range/duty pistol and it is small enough (and so much better than the competition on ergonomics, capacity, etc.) to be the best CCW pistol.
