Frequently Asked Questions

Does this sight set need batteries?

No. The tritium vials are self-illuminating and glow continuously without batteries or a light-exposure charge.

Will this fit my pistol?

It is built specifically for 1911 Government-frame (5-inch barrel) pistols in 9mm/.40 S&W with a factory Novak LoMount dovetail. Some fitting by a competent gunsmith may still be required even on a factory Novak-cut slide.

Is gunsmith installation required?

Installation is generally straightforward on a factory Novak LoMount-cut slide, but Truglo recommends having a competent gunsmith fit and stake the sights for a proper, secure mount.
