Adjustable Rear Sight | Colt Gov't 1911-A1 | LPA Sight

LPA TPU45CT30 Adjustable Front Sight & Rear Sight for Colt Gov't 1911-A1

This adjustable rear sight is a configurable aiming device that replaces your existing sight on the Colt Gov't 1911-A1 with a modern, precisely adjustable variant. The advantage? You can adjust both for elevation and windage, so your sight picture is perfectly aligned for target shooting and practical disciplines.

What we think of this adjustable rear sight

What immediately stood out to us: the finish. This rear sight is CNC-milled from solid steel, and you can feel it. The click screws for windage and elevation are tight and click audibly in steps, so your adjustment does not drift on its own. Also a nice touch: the two white contrast dots make quick aiming considerably easier in normal daylight.

Technical details and optical performance

The rear sight is made of steel and finished in black. Adjustability for windage and elevation is achieved via hardened click screws, keeping your adjustment reliably in place — even under intensive use. The two white dotsprovide a clear sight picture in daylight. Thanks to the robust steel construction, this sighting device is well resistant to recoil and prolonged use.

Other specifications such as the exact dimensions and included tools can be found under the 'More information' tab. The packaging also includes an Allen key and an adjustment screwdriver as standard, so you can get started straight away.

Mounting and compatibility

This rear sight fits the existing dovetail slot of the Colt Gov't 1911-A1 without requiring any milling work. An important detail: the dovetail is a tapered design, meaning it is installed from left to right for a secure lock in the slide. There is no need to replace the existing front sight — this rear sight works in conjunction with the factory front sight.

This is a standalone replacement rear sight component; no complete mounting kit or new front sight is included, only the necessary adjustment tools.

Who is this adjustable rear sight intended for?

This rear sight is ideal for the sport shooter looking to upgrade their 1911-A1 to a finer and more precise sight picture. Practical for anyone who wants to make precise adjustments in static shooting setups and target shooting, without compromising on durability. Even as an experienced shooter looking to refine your setup, this is an excellent choice — the adjustment options give you just that little bit of extra control over your groupings.
