HARRISON DESIGN & CONSULTING 1911 AUTO HD-120 EXTREME SERVICE IGNITION COMPONENTS

Excellent quality parts. The hammer is polished and beautifully finish. Nice serrations on the hammer. Not a drop-in part, but not much work required for a great trigger. I used Ed Brown jig and arkansas + ceramic stones for primary and secondary sear angles, and polished the disconnector where it contacts the trigger bow and sear spring. The machining and polish on the hammer hooks was already as exceptional. The fit of the hammer and sear is perfect.



4 pound trigger job with very little work.

WOW! Great parts. The true radius sear, makes this trigger job, worth the money. Crisp and not too heavy. It really was what I needed, to replace worn out parts. Everything fit good. The hole for the pin, that holds the hammer spur was tight. I just took the edge off the pin, with some 1000 grit sandpaper, so that I could get it started in.This was a pretty easy job. I recommend that it be done by someone with experience.

A very good upgrade to my Para Target Elite 1911, only had to ream strut hole , all parts were a drop in. Functions perfect.--- [ also added Wilson 18 Lbs main spring to reduce trigger pull to about 3 Lbs. ]

Perfect Installed in S&W "E" 1911 drop in fit 3.5/4.0 trigger , Breaks like a glass rod .

I bought this for my SR 1911 Ruger Commander. After watching a couple videos online I started the project. Everything dropped in fine except the pin that holds the hammer strut and fitting the thumb safety to the sear. I had the local gunsmith open up the hammer pin hole and I fitted the safety/sear after reading and watching info online. The trigger has no creep and is sharp and crisp at around 5 pounds.

I was unhappy with the lack of fit and finish on the disconnector in my Kimber Pro Carry II. It was a very rough part. Even after stoning the surfaces, I still wasn't very happy.
I saw that this part had pre-ploished surfaces and decided to check it out.
It's an amazing part. The polished surfaces are silky smooth and the part itself is beautifully machined.
I plan to pick up a few more of these in the future. It's a great part at a great price.

The fit, finish and function of this product are outstanding. No additional stoning or polishing was needed for a perfect trigger.

I did cut the angle on the sear with the Ed Brown Sear Jig and cut the back angle. Adjusted the disconector leaf spring and I got a crisp glass breaking 3.25 pound trigger pull. That is what I was looking for on a target 1911. I have tried other manufacture C&S drop in pull kits and feel these are better quality parts. I did have to make same small adjustments to the thumb safety. I would add a 19 pound main spring and install the 1911 AUTO TITANIUM HAMMER STRUT.

Installed these in my GI Expert ESP and what a difference in trigger pull. Parts dropped right in without any modifications. Going to have to buy a set for my Para LTC.

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.

This set was a drop in fit for my RIA M1911A1. I intalled this kit with a new trigger and boy did it make a difference. Less slack and nice crisp break. Money well spent

These parts were a direct drop in improvement to the look and trigger pull on my Colt MKIV Series 80 Gov't Model. The parts are a matching set and there is a dramatic improvement in trigger feel after the install. Super quality and attention to detail in the machining is evident. Parts are in the white, so there is a risk of rust on the hammer after handling or exposure to salty wet environments, if not looked after- but oil wipe-downs go a long way to avert this. No problems thus far after carrying this pistol.

Excellent material and machining,"Watchmakers Grade". Replaced MIM-Junk in a Kimber Ultra II. Almost "drop in", only mainspring strut pin hole had to be reamed a little. Would recommend to everybody who has some mechanical knowledge and tools (anybody else should not mess with ignition parts anyhow, for safety's sake)
