Sight Picture: i-Dot vertical dot-over-dot configuration – not a 3-dot; designed for faster, cleaner alignment under stress TheGunZone+3Ameriglo+3Range USA+3
Use Case: Ideal for concealed carry, duty use, home defense, competition, and EDC
Fast, Intuitive Dot-Over-Dot Sight Picture
The AmeriGlo i-Dot system uses a single front tritium dot and a single rear tritium dot aligned vertically. Instead of chasing three dots, you simply stack the front dot on top of the rear dot, creating a fast “exclamation mark” sight picture that’s easy to read under stress.

Benefits of the i-Dot configuration:
Quicker vertical alignment than traditional 3-dot sights
Less visual clutter – your eye is drawn straight to the front sight
Excellent for defensive shooting, low light, and rapid transitions
Helps shooters with aging eyes or vision issues pick up the front sight faster
If you want a simple, combat-focused sight picture that prioritizes speed and clarity, the AmeriGlo i-Dot system is a proven choice.
Bright Tritium + LumiGreen Outline for 24/7 Visibility
The SW301 combines Swiss-made green tritium lamps with AmeriGlo’s LumiGreen front outline, giving you outstanding visibility in all lighting conditions: Buds Gun Shop+4Ameriglo+4Custom Gun Solutions+4
Daylight: The bold LumiGreen ring pops against most backgrounds, making the front sight extremely easy to find and center.
Low Light / Indoors: Green tritium lamps glow continuously, providing a clear reference without needing batteries or charging.
Transitional Light (dusk, dawn, indoor/outdoor): The combination of bright outline and tritium ensures the front sight never gets “lost” when the lighting is tricky.
This makes the AmeriGlo SW301 especially well-suited for home defense pistols and carry guns that must remain usable from bright daylight to pitch dark.
Designed for Serious Defensive & Duty Use
AmeriGlo sights are widely used by law enforcement, military, and concealed carriers, and the i-Dot line is purpose-built for real-world defensive shooting. Mounts Plus+2Ameriglo+2
Key defensive benefits:
Rapid front-sight focus: LumiGreen draws your eye to the front, where it belongs.
Simple, repeatable alignment: Dot-over-dot is easy to confirm under stress.
Robust steel construction: Machined steel sights stand up to daily carry, one-handed manipulations, and hard use.
No batteries or switches: Tritium is always “on”, so your sights are ready whenever you draw.
If your M&P is your duty weapon, nightstand gun, or everyday carry, the SW301 gives you an immediate upgrade over plain black or basic 3-dot factory sights.

Have sights installed and zeroed by a qualified gunsmith if you’re not comfortable with sight work.

Loctite (blue) is often recommended on set screws where applicable (follow AmeriGlo / S&W guidance).
Once installed and confirmed, you get a set-and-forget night sight solution that’s ready whenever you are.
