Glock 43X MOS for Sale in Connecticut
The Glock 43X MOS is a slim, single-stack 9mm pistol with a slide machined for a miniature red dot sight. Connecticut buyers can order one online, but the pistol ships to a licensed Connecticut dealer (FFL), not to your home. The dealer checks your State Permit to Carry Pistols and Revolvers or your Handgun Eligibility Certificate before the transfer. The model suits buyers who want a compact 9mm for everyday carry and may later add an optic. The specifications below are the supplier-listed catalog specs for this model.

What MOS and optic-ready mean
MOS stands for Modular Optic System. The MOS slide is machined for mounting a compatible miniature red dot sight, which usually attaches with a mounting plate. Optic ready means the slide is prepared for that kind of sight. The pistol still comes with standard fixed sights, so it works with iron sights if you do not mount an optic. A sight is a separate purchase, and the listing does not include one.
Single-stack describes the magazine. The rounds sit in one column instead of two staggered columns, which keeps the grip narrow. The Glock Safe Action system uses a trigger pull that stays consistent from shot to shot. The listing describes three automatic mechanical safeties that reset when the trigger is released.
Size and carry
The listing gives an overall length of 6.5 inches, a barrel length of 3.41 inches and a weight of 18.7 ounces. The polymer frame has a compact grip and an integrated beavertail. The supplier describes the pistol as designed for comfortable concealed carry. How a specific holster or clothing setup works for you depends on your body, your holster and your daily routine, so try the grip in person if you can before you commit.
Carrying the pistol in Connecticut is a separate legal step from buying it, and it requires a permit. Carry needs a temporary state permit from your local authority, then a five-year State Permit to Carry Pistols and Revolvers from DESPP, which you must apply for within 60 days. You also need a handgun course with live fire, at least at the NRA Basic Pistol level. Open carry has been barred since October 2023.
Connecticut credentials and the 10-round limit
A handgun transfer in Connecticut requires a State Permit to Carry Pistols and Revolvers or a Handgun Eligibility Certificate. Both are available to buyers who are 21. The dealer submits the background check through DESPP and receives an authorization number. Connecticut sets no fixed waiting period, and a buyer may purchase no more than three handguns in any 30-day period.
Connecticut does not allow magazines holding more than 10 rounds to be sold into the state. The listing shows 10+1 capacity and two included magazines. The Connecticut dealer will transfer this model only if the pistol and its magazines, which must hold 10 rounds or fewer, are legal in Connecticut. Ask the dealer to confirm the magazine configuration before you order.

Frequently asked questions
Can I order a Glock 43X MOS online in Connecticut?
Yes, with conditions. You pay online and the pistol ships to a Connecticut licensed dealer you choose. You cannot take delivery until the dealer has checked your permit or certificate and completed the background check.
Does the Glock 43X MOS come with magazines?
The supplier listing says two magazines are included, each rated at 10 rounds. Connecticut magazine rules still apply, so confirm with the dealer that the magazines are legal for transfer into the state.
Do I need a special permit to buy this pistol in Connecticut?
You need a State Permit to Carry Pistols and Revolvers or a Handgun Eligibility Certificate to take delivery of any handgun in Connecticut. A Handgun Eligibility Certificate covers buying only. Carrying outside the home requires the State Permit to Carry, which also satisfies the purchase requirement.
What does optic ready mean for a new buyer?
It means the slide accepts a compatible miniature red dot sight. The pistol ships with standard fixed sights. You can shoot it with those sights, or buy a compatible optic and mounting plate later.
