Liability concerns prevent me from posting a full set of instructions, but I can tell you that the R1's trigger pull can be greatly be improved upon.
It takes a decent bit of mechanical knowledge or intuition, and a few common tools.
Mine now breaks at a comfortable and safe 64 oz.
It used to be somewhere around a brick and a half.
The first thing you'll need to do is to remove the trigger group assembly from the receiver.
Once you have it out, carefully **** the mechanism and pull the trigger. It helps to hold the hammer back and let it travel in small increments. Pay careful attention to how the parts interact, and which surfaces work against each other.
There should be two particular points of contact which will enlighten you as to where to apply your efforts.
You'll also see where the trigger creeps. Although not much can safely be done about the creep, it does at least allow you to see what's going on and when the creep comes to the end of travel.
Knowing this when shooting the R1 should help you with your technique.
It's almost like a two stage trigger.
If you mess around with it enough, you'll notice that the return sping on the trigger accounts for about 24 oz. of the total pull weight.
I DO NOT recommend trying to shorten or modify this spring, or any other springs, in any way whatsoever!
Work patiently, diligently, and test, test, test as you go.
Mine took about an hour to get it to where I wanted it.
From the pictured items, you should figure out that polishing is a large part of the improvement process.
Remove metal only at YOUR OWN RISK!

If you don't understand what you're doing, then don't do it!
Take it to a professional.
