Comparing the T05 trigger to the T06: Part 3
by B.B. Pelletier
Pro-Guide spring retainer system for RWS Diana rifles: Part 5 — The RWS Diana 34 Panther
I’m testing the T06 trigger today using the accuracy test as a means to evaluate the operation of the trigger. The object is not to see how accurate this RWS Diana model 34P is. We already know that from tests run long ago. But as I try to shoot groups with the gun, I can get the feel of the new trigger better than any other method. So, today is about a trigger and not about this air rifle.
Of course, I’ve already used the trigger a lot in the velocity testing I did a couple days ago. Now, however, I’ll be holding tight on a small target, and any aberration in the trigger will come though loud and clear. This is where the rubber meets the road!
New BKL adjustable mount
I’m also testing the new BKL adjustable scope mount at the same time, and the next report will be exclusively about that. I showed you the new mount in Part 1, but what I didn’t show you was the bubble level that’s attached to the left side of the mount base.
With this level attached, I can sight with one eye and watch the bubble with the other. I can’t see both at the same time, which is why a scope with an internal bubble level would be so desirable, but at least I don’t have to move my head to see the bubble like you do with some other levels. I’ll be reporting on it when I cover the mount in the next report.
Back to the accuracy test
I learned in the past that this rifle really likes 7.9-grain Crosman Premiers, so instead of fooling around with many different pellets, I selected just these pellets for the test. That way I could forget about trying to make the rifle shoot well and concentrate on the trigger.
Though I’m only showing you a single 10-shot group, I shot much more than that. I probably shot 50 shots for today’s test, on top of about 20 the day before when I was checking out and adjusting the new mount. With all this testing, I became very familiar with the T06 trigger.
How the T06 trigger differs from the T05
The T06 operates differently than the T05 did. The T05 stopped cleanly at stage two and held there until the instant the sear released. There was no feeling of movement once stage two was engaged.
The T06 also stops cleanly at stage two, but as you continue to pull you can feel the trigger moving through the stage. Normally this is called creep, but it is absolutely smooth with no pauses or hesitations, and it doesn’t fit the popular definition for trigger creep. In fact, this movement becomes entirely predictable and something a shooter can learn to live with.
Something else about the stage-two pull on the T06 — on most triggers, when you pause part way through stage two, back off and then return to it again, as much of it that was pulled through is still gone. You’ve advanced the trigger or shortened the stage-two pull, whichever you prefer. Not so on the T06.
Because the Diana 34P requires so much technique (the artillery hold) to shoot accurately, I found myself stopping several times before the trigger released to take another breath. When I did that, naturally I relaxed my trigger finger as well. Then, I had to settle myself again before returning to the trigger. What I found when I got back on the trigger was that it had reset itself to the start point. The full trigger-pull was restored. This is what I want all triggers to do, because anything else means an unpredictable trigger that could release before I’m ready. From that standpoint, the T06 is a very nice trigger. The T05 didn’t have the problem of pulling part way through stage two, so of course it always acted like it had just been set whenever you came back to it as well.
The bottom line
Diana has made a change with the T06 trigger. In my observation, it isn’t any better or worse than the T05; it’s just different. If you want a metal trigger blade, the T06 has it. If you want adjustments, the T06 has more of them. I wasn’t able to eliminate the travel in stage two, but that doesn’t mean it can’t be done. I spent all of 30 minutes adjusting the unit. Someone who is willing to put in more time can probably discover secrets that I didn’t find.
The bottom line as far as I see it is the T06 trigger is now here and the T05 is a thing of the past. I alerted you to the difference between the T05 and T06 pistons, so you know they go together and a T01 trigger can also use the same piston as the T05.
The new trigger is nice and predictable. It has the features I’ve mentioned, and they all work well. If you wind up with one on your next Diana airgun you should be satisfied with it. But if you currently own a T01 or a T05 trigger, I wouldn’t plan to change it.
