HELLO MR GURU
I wonder what it takes to improve the trigger on my rifle. It’s a two-stage unit and feels a bit heavy in the final pull, so I’d like to improve it, but I worry about making it dangerous. What can I do? PETER SMITH A
Most high- quality airguns have adjustable triggers and when you understand what they do, making an improvement is just a matter of small changes, a little at a time. Firstly, read the manual or look it up on-line. All the important information is there. Secondly, remember that keeping the trigger in a safe condition matters more than anything else.
Please make any changes 1/8th of a turn at a time, and note where you start from so that you can easily go back again.
There are two factors that I feel make the biggest difference in trigger performance. The first is pull weight. Too many people try to adjust their trigger to be very light but this is a bad idea. I believe that two pounds is the ideal weight for sporting rifles and most high- quality triggers can be set to this. Secondly, the length of travel of the second stage has a big effect on your ability to release shots at the very moment you want. The manual will explain how to adjust both factors.
Once you have your trigger just how you like it, torture test it until you feel completely sure that you’ve done nothing wrong, and that it is fully safe. With the action cocked and loaded, aim the rifle in a safe direction, be that on the farm or range, and set about shaking it, bumping it with your fist, and finally smacking the butt pad violently with your hand. Nothing you can do with your hand will damage the gun. As long as it refuses to fire, you’ve set the trigger sensibly and you can enjoy the improvements with a clear conscience.
Make your adjustments in very small steps, and test the rifle after every change
