Frequently Asked Questions

What are the key custom modifications made to the Kimber Eclipse Custom 2 in the video?

The Kimber Eclipse Custom 2 received a full heat treatment on its stainless steel, an Ed Brown Match Fit threaded barrel in .45 ACP, Crimson Trace laser grips, a Fusion Firearms mainspring housing with a lanyard loop, and a Wilson Combat safety. A custom single-stage trigger job was also performed.

What benefits does the custom trigger job offer on this 1911 build?

The custom single-stage trigger job aims to eliminate take-up, provide a crisp break described as like a 'glass rod,' and feature a very short reset, significantly improving the firearm's shootability and precision.

Why are suppressor-height sights mentioned as a notable feature?

Suppressor-height sights are highlighted because they are becoming increasingly difficult to find. They are essential for users who plan to mount a suppressor, allowing the sights to be visible over the suppressor, or for co-witnessing with a red dot optic.

What is the significance of the Fusion Firearms mainspring housing with a lanyard loop?

The Fusion Firearms mainspring housing replaces the factory plastic part with a more durable metal component and includes an integrated lanyard loop. This feature is valuable for tactical applications or duty use where securing the firearm via a lanyard is desired.
