1911 AUTO HD-120 EXTREME SERVICE IGNITION COMPONENTS Reviews & Ratings

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. Hammer hooks are pre-prepped and sear nose polished for precise contact and crisp, clean letoff. Commander-style hammer has elongated spur with deep serrations to provide extra-secure thumb purchase. Beveled edges resist snagging on clothing and protect the thumb from abrasion, and slightly narrower hammer body prevents unwanted slide contact. HD-120 set includes hammer, sear, and disconnector. Each component also available separately. HD-120B set features a black IonBond DLC coating on the hammer, for those who prefer the traditional “blued” look combined with wear- and corrosion-resistance similar to hard-chrome.

SPECS: Hardened tool steel, in-the-white. Hardened to Rc 53-56. HD-120B set’s sear has a black IonBond DLC finish. Some fitting may be required.

makes a fair drop in

good looking part but not made for any of the colts I tried to fit the head is to lose in the port at the pistol I could feel it moving when pulling on the trigger my shooters complained of this and I had to go with EGW I'd rather take of to fit correctly than have a less then drop in part.

perfect!!

I have a Springfield 1911a1 and this was, for the most part a drop in kit. the frame safety needed some slight filing to function with the new sear. My stock sear,discon.,hammer worked great but it wasn't smooth and solid. this is all that. the only reason I put 4 stars is because it might take slight modification that is'nt advertised in the description.
