What is the Best Glock 43 Red Dot? 🔴
The Glock 43 is a subcompact 9mm pistol that was introduced by Glock in 2015. It is their smallest 9mm pistol and was designed for concealed carry use. It has a slim profile making it easy to conceal while still maintaining a 6+1 round capacity. In recent years, many owners have chosen to mount miniature red dot sights onto their pistols.
Adding a red dot sight provides faster target acquisition and improved accuracy compared to traditional iron sights. The small size of the pistol makes finding the right variant challenging, but companies like Shield RMSc and Holosun have released mini models perfect for this pistol. The combination of the easy-to-conceal gun and a low-profile red dot has made this one of the most popular concealed carry setups on the market today.

Factors to Consider When Choosing a Red Dot Sight 🔎
➡️ Here are some factors to consider when choosing:
- 📏 Size: Since the gun is a subcompact pistol, you’ll want a small RDS that doesn’t add too much bulk. Look for micro or mini RD sights.
- ⚖️ Weight: Adding too much weight to the slide can affect the cycling and balance of the pistol. Look for lightweight RD sights made of aluminum or polymer.
- 🔨 Durability: The RD needs to withstand recoil from a 9mm round. Look for dots made for handguns. Features like auto-brightness help with longevity.
- 🔧 Mounting: You’ll need to find an RD that fits the slide cut on your gun. Some opt for direct milling the slide for a specific dot. Others use mounting plates for red dots like the Shield RMSc.
- 👁️ Co-Witness: Being able to see your iron sights through the RD window is preferred for backup sighting. Lower 1/3 co-witness is common for microdots on the 43.
- 🔋 Battery Life: Long battery life reduces the need to change it often. Look for dots with at least 1 year of constant on life. Automatically turning on when moved helps conserve battery.
- 💰 Price: They range from around $200 into the $500+ range. Set a budget that fits your needs. Quality dots don’t have to be expensive.
👌 Choosing the right RD sight for your gun comes down to finding the best features and fit for your intended concealed carry needs.
