    I have been on a revolver kick lately ( picked up a 4 and 6 inch GP100 and an SP101) But the more I handled them I didn't like the heavy Double action trigger pull. Started doing research, Ordered some parts and waited for the right time. Well since it is so cold out I decided to start working one of them over.
    I did some polishing, added some hammer and trigger shims, lapped the crown and boy was I surprised after reassembly. I went from a 10.2 lb double action to a 5.5 lb double action.

    I can not wait to get to the range and try it out. Amazing what we find to do on a cold day isn't it?

    That's amazing. I honestly didn't realize you could make a DA revolver lower than, oh, 8lbs.

    Let us know how it shoots, hopefully there aren't any issues!

    That is amazing! Five and a half pound double action trigger? Dang. Not to be a negative Nelly, but taking that much off the trigger I would be worried about light primer strikes. I'm not a revolver expert or a gunsmith, but that is a truly impressive reduction in trigger pull. I'm curious to hear how they perform when you next go to the range.

    Didnt take anything off the trigger. The only thing that was used was polishing compound and springs. I know better than to use a file or anything else. You can smooth up and make pretty but if you use a file you cant replace metal.

    I meant to say trigger pull, but knowing that nothing was filed makes it that much more impressive.

    If you massage them right, rugers can be really smooth. My 1708 GP100 needs a lot of work. A lot of material left in the action. Patience is key.

    At a 5 pound pull, I'm pretty sure this gun is not going to run reliably.

    Sure it will. No dimensions were changed. I just made them mirror smooth and changed the spring from a 14 lb to a nine pound. First decent day I get Ill run a couple hundred rounds through it and verify. But I am confident in my work and where I learned this process.

    I'm concerned just because pull weight is cut in half (sounds too good to be true), but I don't doubt anything except the 9lb spring. Even then I'm cautiously -optimistic-

    If it works, I really really do want to know. And I wish you the best!

    place a 1/4 dowel rod @ 12-14" long in the barrel of a cocked unloaded gun ,and pull the trigger with the gun muzzle pointing at the ceiling ,when the trigger is pulled and the hammer falls the dowel rod should come within a foot of touching the ceiling if you are sitting on a chair .This will show if the F.P. strikes are hard enough to set off primers

    Looking forward to hearing how it does! I have a Manurhin MR73 (in my avatar) that has an adjustable trigger, and when fiddling with it, I adjusted it to the point where I was getting light strikes. Tightened it back up a little until I got reliable ignition. It's a wonderful trigger but I don't think it's as light at yours.

    Marking for intetest. I have an SP101 that long ago I just decided to live with the DA pull. Quite curious to see how this turns out.

    I understand that he is good but I prefer to do my own work and learn how to do it. I have several Armorers Certificates and have self taught myself on several other platforms. I don't use files or stones because then I risk changing dimensions. I have found that just a little time and polish gets the best results. I am a firm believer in knowing my firearms.
