GRT III – Drop-In Replacement Trigger
Finally a solution? We’ll see.. Have I mentioned that I don’t care for the Crosman and Gamo triggers? You know I have. They are stiff and have a tendency to be unpredictable. Both lines have some really accurate rifles. The Gamo 440 is a great gun and the Crosman G1 and 800x have a lot of potential given the gun is working right. But they all suffer from rotten triggers. I’d rather they keep the scopes and put a really nice trigger system in. Anyway, enough of my ranting.
There is hope however. I came across the following web site, https://www.charliedatuna.com/index.html. I don’t know how I got there, but I was pleased to find they carry a drop-in replacement for many rifles. I didn’t realize just how many rifles use the exact same design, but supposedly this trigger will simply drop-in all the following air guns.
GRT-III Trigger… yep, that’s all there is to it!
The GRT-III trigger blade will fit almost any rifle using the Gamo type trigger including:*
- Beeman S-1
- Cabela’s Outfitter Series (all)
- Crosman Quest 800
- Crosman Quest 1000
- Crosman Phantom
- Crosman G-1 Extreme
- Daisy 130b
- Gamo CFX series
- Gamo Hunter all series (including the 1250)
- Gamo Shadow all series
- Gamo Recon
- Gamo Nitro 17
- Gamo 640 Carbine
- Gamo (all late production rifles)
- Meteor MK-6
- Rapid MK-1
- Remington Summit
- Some QB models like the 88
- Some other TF models
- TF-25 ??
- And some others.

Now the term “drop-in” can mean several things. In this case it is literally a “drop-in” procedure. They have detailed color instructions on their site and the process takes about 5 minutes if you know what you are doing. It took me 10 minutes the first time, but the second rifle was a snap.
GRT-III Trigger Installed in Crosman 800x
There is not much to this thing. It completely removes the trigger return spring that makes the original trigger so hard to pull and just relies on the internal spring on the sear for tension. I don’t have a gauge to measure the pull weight but it is light, almost too light. There are two adjustments. One is for the first stage and the second is for the second stage. There is a lot of information on their site that goes into great detail about how these triggers work.
GRT-III’s 2 adjustment screws
Now down to the nitty-gritty. I purchased 2 sample triggers. I installed one in my Gamo 440 and one in our test Crosman 800x. The difference was dramatic. My Gamo shoots like a dream now. In fact just two days ago I made an impossible shot at almost 90 yards. There is NO way I could have made that shot with the old trigger. The pull is very light and distinct and with a careful pull you can clearly feel the first and second stages of the trigger. I’m thinking .25″ groupings at 20 yards are now possible with this riffle. As for the Crosman 800x, the difference was equally dramatic. The groups reduced by more than half with the new trigger in the 800x. (I’m going to take another look at the Gamo 440 with this new trigger so keep checking the site for the article)
All in all, I’m very impressed with this new trigger. If you have one of these compatible rifles and you are looking for a better trigger that DOES NOT take ANY modifications to the original mechanism, then take a serious look at the GRT-III Trigger. However, when you add $32 to the cost of a $130 or $150 rifle, you may find that you’d be better served to get a BAM-B26 that has a great trigger right out of the box. I would not buy a new Crosman G1 with plans to purchase a GRT-III trigger, when there are choices out there with good factory triggers in the same price range.
