I wonder how it compares to a Sig P365.
“The Glock 43X has a slightly longer 3.41-inch barrel compared to SIG’s 3.1-inch long barrel. The overall length is where we see a big difference and the Glock 43X is 6.5 inches compared to the P365’s much shorter 5.8 inches. The Glock also weighs 23.07 ounces compared to the lighter P365 which weighs 17.8 ounces. Overall the Glock 43X is a larger and heavier firearm. This can make it easier to handle and shoot. It also has a longer sight radius which can contribute to an easier to shoot gun. However, the SIG’s smaller size makes it easier to carry on a day to day basis.
The big deal with these guns is the fact they are hardly bigger than pocket pistols but on average hold 40% more ammo than a standard handgun. Both guns come with ten-round magazines. The Glock 43X magazines are separate from the Glock 43 and the extended Glock 43 magazines will not function with it.
The primary benefit to the SIG P365 is the ability to utilize 12 and even 15 round magazines. These are SIG OEM magazines and allow for even greater capacity versus the Glock 43X. These magazines do make the gun longer, and heavier, but the increased capacity may be worth it to some.”
