Specifications: Sig P365 vs Glock 43
Size & Capacity
When comparing the Glock 43 vs P365 in size, you’ll see the two pistols are incredibly similar in size with the P365 coming in slightly smaller despite its higher round capacity.
The Sig Sauer P365 is 4.3” tall, 5.8” long, and 1.06” wide, with a barrel length of 3.1” and a weight of 17.8 ounces. The Glock 43 is 4.25” tall, 6.26” long, and 1.06” wide, with a barrel length of 3.41” and a weight of 17.99 ounces.
The Glock 43 capacity is 6+1 rounds, while the Sig P365 comes standard with a 10-round magazine. Both pistols have extended magazine options to increase the capacity if that is something you are looking for.
The Sig Sauer P365 is built with a micro-compact black stainless steel frame and finish and a polymer grip. If you are looking for a little extra grip length, you can replace the frame with the longer Sig P365 XL frame, though the standard frame works great as-is.
The Glock 43 is built with a black polymer frame and built-in beaver tail design for a high and tight grip.
Slide & Barrel
While the Glock 43 features a Tenifer-coated ordinance-grade steel slide, the Sig P365 has a stainless steel slide with a Nitron finish and carbon steel barrel. Both finishes are designed to protect against scratches and corrosion.
When it comes to serrations, the P365 takes the lead. The Glock 43 features no front or rear serrations, while the Sig Sauer P365 has both.
Sights & Optics
If sights are important in helping you choose which gun is right for you, the Sig P365 is the clear winner.
The P365 comes standard with Sig’s X-RAY3 day and night sights, a 3-dot tritium system designed for natural target acquisition in any lighting condition. The X-RAY3 has a 4.9” sight radius and is crafted with an oversized chemical-resistant fluorescent polymer front dot. The tritium sights are surrounded by steel to protect them from recoil, cleaning solvents, and the elements.
The Glock 43 comes equipped with Glock’s standard plastic sights. This doesn’t have to be a dealbreaker, however, as both gun models are easily upgradable to sights of your choice.
Neither of these guns comes optics-ready or is available in an optics-ready variation.
If you are looking for a gun with a manual safety, the P365 comes out on top.
While neither gun comes standard with a manual safety, the P365 is now available in a version that does offer a manual safety option. The Glock 43 features Glock’s internal Safe Action Trigger System.
The Safe Action System does provide protection if the pistol is dropped, though it doesn’t offer the same protection as the Sig’s manual safety.
When comparing the trigger of these two striker-fired pistols you’ll find they have approximately the same pull weight of approximately 6 pounds.
Which is Right for Me?
At the end of the day, you can’t go wrong with either the Glock 43 or the Sig P365 for concealed carry or home defense.
Ultimately, when comparing the Sig P365 vs Glock 43, it comes down to what fits your needs. If you are looking for a higher capacity or better sights, the Sig Sauer P365 might be the best choice for you. On the other hand, if you want everything a full-size Glock has to offer in a more concealable size, the G43 may be the right choice.
