PRODUCT DESCRIPTION
Do you want to drastically reduce the trigger pull in your pistol without sacrificing reliability? The hammer mainspring for 1911 / 2011 platforms from the renowned performance parts manufacturer Eemann Tech® is a key tuning element of the hammer and trigger mechanism. Designed with sport shooters in mind, it allows for precise customization of the weapon's performance characteristics and achieving perfect fluidity of every shot.
The heart of trigger tuning – Reduce pull and maintain reliable ignition
In the classic architecture of 1911 and double-stack 2011 pistols, the mainspring (located inside the mainspring housing) is directly responsible for the force with which the hammer strikes the firing pin, but it also has a huge impact on the force required to break the trigger. Replacing the factory, stiff spring with a competition-grade equivalent from Eemann Tech allows for reducing the trigger pull weight, which directly translates into better grouping, a lower risk of jerking the shot, and a shorter reaction time on the range.
Match the spring weight to your ammunition (Wide range 14 lb – 18 lb)
To meet the rigorous demands of competitive shooting, Eemann Tech springs are available in precisely calibrated weight variants (expressed in pounds – lb):
-
Lighter variants (14 lb / 15 lb): Created for uncompromising competitive sport in IPSC and IDPA. Drastically lighten the trigger, ideal for use with soft sport primers (e.g., Federal, Fiocchi).
-
Intermediate and standard variants (16 lb / 17 lb / 18 lb): An excellent balance between sporting lightness and absolute versatility. They guarantee reliable ignition of harder primers (e.g., CCI, S&B) and factory ammunition and reloads with tougher components.
Highest quality steel alloy and cycle repeatability
Eemann Tech gunsmithing components are made from the highest quality spring steel subjected to advanced heat treatment. This guarantees consistent performance characteristics and resistance to material fatigue – the spring does not "set" over time, maintaining its nominal power even after tens of thousands of hammer strike cycles. This is an investment in repeatability, which is essential during long, demanding dynamic competitions or intensive tactical training.
