Description
The TRUGLO TFX sight set is one of those upgrades you notice the first time you pull your 1911 in low light. It blends Swiss tritium with fiber-optic elements so the front and rear dots stay bright and easy to pick up around the clock, no batteries or charging required. The fiber-optic feeds the sights during daylight while the tritium takes over once the sun drops, giving you a consistent green three-dot picture in just about any lighting.
How the TRUGLO TFX Sights Handle Real-World Use
The front sight carries a bright white focus ring that pulls your eye straight to it, which makes fast target acquisition feel almost automatic. The whole package is built compact and snag-resistant so it clears a holster clean and won't hang up on a draw. TRUGLO seals the tritium and fiber into a hermetically sealed capsule, so the delicate elements shrug off oils, solvents, and even ultrasonic cleaning without dimming.
Build Quality of the TFX 1911 Sight Set
These sights are CNC-machined from solid steel for tight, model-specific tolerances, then coated in TRUGLO's rust-resistant Fortress Finish for lasting protection. The longer sight radius on a 5-inch Government frame helps tighten up your groups, and the low-profile design fits standard holsters without drama.
Fitment for the TFX Novak LoMount Set
This set (model TG13NV1A) is cut for the Novak LoMount dovetail with a .260-inch front and .450-inch rear height, matching 1911 5-inch Government .45 ACP configurations and compatible Ruger SR1911 models. It's a drop-in dovetail sight, though a sight pusher and professional installation are strongly recommended to seat everything square. TRUGLO backs the set with a 12-year limited warranty, so you're covered for the long haul.

Frequently Asked Questions
Will the TRUGLO TFX TG13NV1A fit my Ruger SR1911?
Yes, this set is cut for the standard Novak LoMount dovetail and works with compatible Ruger SR1911 models chambered in .45 ACP alongside 1911 5-inch Government pistols. The .260-inch front and .450-inch rear heights are matched to that configuration. As always, confirm your pistol uses the standard Novak LoMount cut before ordering.
Do these TFX sights need batteries to glow at night?
No batteries and no charging needed. The night glow comes from Swiss tritium, which produces its own light continuously, while the fiber-optic elements handle brightness during the day. That means the sights are ready to go whenever you are, day or night.
Can I install the TFX 1911 sights myself?
These are dovetail sights, so a sight pusher tool makes the job far easier and helps you seat them square. Some folks have tapped them in carefully, but professional installation with proper equipment is strongly recommended to avoid damaging the sights or your slide. A gunsmith can also help you center the rear for accurate point of impact.
How durable are the tritium and fiber-optic elements?
TRUGLO seals both the tritium and fiber into a hermetically sealed capsule that resists oils, chemicals, solvents, and even ultrasonic cleaning. The steel bodies wear a rust-resistant Fortress Finish for added protection. The set is also backed by a 12-year limited warranty.
