Description
The Meprolight Tru-Dot adjustable sight set is built for shooters who want serious control over their zero. Unlike fixed sights, the rear sight features full windage and elevation adjustments so you can compensate for different distances, ammunition weights, and shooting conditions without changing sights. The front sight is fixed, keeping things simple while the rear does the work.
What sets these apart from the competition is brightness. Meprolight's Tru-Dot design uses premium-grade tritium that runs roughly 20% brighter than other night sights on the market. The dots appear as solid white outlines during the day for fast acquisition, then glow a vivid green at night for precise aiming in any light. There's no transition needed between daylight and low-light shooting since the aiming reference stays identical from sunrise to midnight.
Steel construction built to handle recoil
These sights are forged from metal that stands up to repeated impacts and harsh field conditions. The tritium vials sit protected within durable metal housings, and the whole assembly resists solvents and cleaning chemicals that would degrade lesser sights. Installation requires professional gunsmith work with proper dovetail tools, but once mounted and dialed in, these sights stay put through thousands of rounds.
P220, P225, and P226 compatibility
These adjustable sights work on all three pistol models, though the P220 (.45 ACP) technically uses a #6 front with #8 rear sizing, while the P226 (9mm) uses #8 front and rear. Meprolight engineered these to work across the lineup with minimal fitting, though you may need your gunsmith to verify perfect fitment on older examples. The 12-year usable illumination warranty covers the tritium vials if anything dims unexpectedly.

Frequently Asked Questions
Do these P220/226 sights require a gunsmith to install?
Yes, professional installation is strongly recommended. These sights use dovetail mounts and require precision tools to drift in and out safely without damaging the slide. Improper installation can crack sights or misalign them, so a qualified gunsmith with sight-pressing equipment is your best bet.
Can I use the P226 sights on a P220 or vice versa?
These sights are designed to work on P220, P225, and P226 models. However, the P220 (.45 ACP) normally runs #6 front and #8 rear sizing while the P226 (9mm) uses #8 front and rear. The Meprolight set works across all three with minor fitting, but your gunsmith should verify the dovetail alignment before installation to ensure proper fitment.
How bright are the tritium dots at night compared to the original SIG sights?
Meprolight tritium is roughly 20% brighter than most competitor night sights, including standard SIG Sauer tritium sights. The green dots glow noticeably vivid in complete darkness and remain visible for the full 12-year lifespan of the tritium vials, though brightness naturally fades very gradually over that period.
What if I need to adjust my point of impact after installation?
The rear sight has both windage and elevation adjustment turrets so you can dial in your zero at the range without removing the sights. The front sight is fixed, so all adjustments happen at the rear. This lets you compensate for different ammunition, distances, and shooting conditions by simply turning the adjustment knobs.
