Range officer trigger

Post by Jake1911 on 1/28/2018, 6:08 pm

I use a range officer lower for my 22 Nelson conversion. I can’t go below 2.5# trigger or It won’t be reliable. Do I need better quality hammer and sear and if so what works the best? Thanks

My guess is that's about the safe limit for that design.

I got my Caspian down to 1.75 with C&S parts and Radius Roll Trigger and a crazy amount of attention to the trigger bow. I now shot #3 because I find with a 1911 too light does not get me better scores. 

Yer Yev also has a section in his book about too light a trigger. 

Having said that you probably want a trigger that can go down to 1.75 because at 3 it will be utterly consistent. 

If the trigger is good, my suggestion is to take the bow out clean the tracks and if you have the right stone stone the tracks. Then look at the top and the bottom of the blade. If there any witness marks take some 800 grit sand paper and polish them up. Then adjust the bow, gravity should let the bow drop into place. From a stock gun doing that should get ride of a ton of creep and drop the pull weight 4 to 6 ounces. If it drops in and the 22 mags don't touch the inside of the bow it will feel good. 

I would not mess around with the hammer and sear unless you have new parts on hand and really study up on doing trigger jobs its not an easy skill and the tolerances are sometimes too small to see unmagnified. 

When all is said and done do all the safety checks at least twice because with light weights it could work a couple of times and fail.

Trigger job on a .22 conversion is more difficult than 9mm or 45.
Slide is haulin' booty and you get sear bounce if less than ideal parts in the pistol. 2.25# is fairly simple. 2# takes more skill.
Look on internet for Bob Marvel notes on trigger jobs for conversion. Good reading.

I could not find it but if you have the link it would be greatly appreciated. I would like to know what I did right by accident.

probably not the exact article Jon is referring too but this is a paper put out by Bob Marvel on areas that can cause issues with the conversion.. some trigger work is described here.

in the article he mentions sear length being too short.. most factory sears are short compared to custom aftermarket sears.  STI and E2 sears are great starting points. E2 makes parts for many folks selling hammers, sears, and hammer struts.

I am very very happy with a KC kit in a Range officer and Nelson.  Total drop in for me.

You want a trigger group worked over by a BE Smith. The parts I mentioned are good quality parts but that's just a start.

If you like a roll trigger lots of folks have had great results with his set .  Best results are received by having the entire ignition set done on your pistol by a smith..

I like extreme engineering about the same if not better quality as C&S. Send it to Jon, KC, or Dave Sams. Do not do a 22lr trigger job yourself unless you have experience doing fine detail work 

Sear too long Disco too short and 8 million other things can drive you bat shit crazy. 

Also unless you are using NRA weights there is a good chance the scale over estimating the weight.  #3 could actually be 2.5 on the NRA weights.

My plan was to buy a quality hammer sear combo and send to a quality Smith for a nice trigger job. Is there a particular e2 that works better than the others for a conversion?

You might want to pick out your smith and talk to them before getting your parts.
