Harrison Design 1911 Extreme Upgrade Kit Includes the following components:
- Extreme Service Ignition Set
- Extreme Service Short Trigger (blued or silver)
- Extreme Service Slide Stop (blued or SS)
- Extreme Service Magazine Catch (blued or SS)
Critical ignition parts are machined from high-grade tool steel for precise fit and reliable, consistent function under the most demanding operating conditions. Each component is wire-EDM cut, CNC machined and honed to final dimensions with +/-.005" tolerances for drop-in fit on many 1911s, then heat-treated to Rc 53-56 to maintain those dimensions through thousands of firing cycles.
High-performance trigger is built for shooters who run their guns hard, yet want a precise, smooth, consistent trigger pull. Solid aluminum shoe gives a comfortable, natural finger position to help prevent uneven pressure that can compromise accuracy.
CNC-machined to precise dimensions from high-grade steel forgings, these slide stops feature a smooth, low-profile thumb pad that won’t snag on holsters or clothing. Pad’s unique, curved geometry still ensures positive engagement under stress, with cold hands, or when wearing gloves.
Heavy duty tactical magazine catch ensures secure mag retention and fast, reliable release under extreme service and competition conditions. Serrated button is 1⁄16" taller than factory button to provide positive, non-slip finger contact to help you drop the magazine on the first attempt.
