A few years back, I decided to jump on the gas ram bandwagon, purchasing a Umarex Fuel, and leaving my Gamo Shadow 1000 to rot in the gun cabinet. Over time, my Fuel has gotten weak. The breech seal and piston seal are good, so it’s looking like the gas ram is losing its magic sauce. Ordering parts through Umarex isn’t my favorite thing to do, so I decided to pull the Shadow out and dust it off.
Much to my surprise, it shoots extremely fast and consistent in spite of the years of abuse it has endured. Lighter pellets shoot in the 920 range and heavy pellets shoot in the 710 range. The Shadow is so light compared to my Fuel, making it better for carrying around in the woods. On the downside, it is very twangy and the trigger pull is really bad. If I can fix that trigger, I’ll give it a good tune and turn it into my go to magnum springer.
The Shadow comes with a short trigger adjustment screw. I rummaged around my spare parts and came across a longer screw with matching threads:
Note the pin riding in the slot above the trigger blade. As you squeeze the trigger, that pin engages a lever between the trigger and the sear. If I can bring up the diameter of that pin a tad, I should be able to get rid of virtually all the creep. I used a bit of copper wire bent around the pin to do just that:
Time to put it all together, adjust the screw, and make sure everything works safely. I recommend taking it outside for testing. I begin by making sure the sear catches. A pellet is then loaded while holding the barrel open to prevent dry firing. The trigger is squeezed with the safety on to make sure it is working order. I then proceed to slap the stock hard several times to make sure it will not accidentally discharge. When you get it all right, you end up with a trigger like this:
The safety works, there is zero creep, and a light squeeze of the trigger fires the gun. I’m very pleased with these results. One thing will make this a perfect single stage trigger: eliminate over travel. I’ll save that one for a later time.
