My Impact arrived back from AoA today. I don't have time to retest everything tonight, but I will share the first update on one of the repairs. The trigger on my Impact from the factory was terrible. Like 1/2" travel in stage 1 and stage 2. The trigger pull weight was in the 3 pound range. I spent a little time working on it and gave up on how far off it was from a good setup for a "match" trigger as I had other issues with the gun and I wasn't going to make modifications to try and fix them. My exact quote to AoA in the return letter was
The “match” trigger on this gun came from the factory more like a trigger on a $100 Walmart rifle. I can set my other guns to work reliably at a few ounces of pull with no first stage travel. Can’t do that on this Impact (it’s back to factory)."
So what in my book is a match trigger? Let's start with what the ISSF (International Shooting Sport Federation ) states is a match trigger spec for a 10M air pistol : 500 grams or about 1.1 pounds. So here is my first video for AirGunNation so folks can see how I'm testing this gun vs me stating "the trigger is terrible" or "this trigger is great". This is my Steyr EVO 10 with a Lyman trigger gauge doing an objective measurement vs my 50 year old trigger finger with 40+ years of pulling triggers making a statement.

Now, a 10M competition air rifle with a match trigger doesn't have a minimum ISSF spec when it comes to trigger pull. Many of these modern 10M rifles come from the factory in the 100-200 gram (3.5 to 7 ounce) pull range. Many of the club shooters then set them up between 60 and 120 grams (2.2 to 4.2 ounces). My statement to AoA was my other air rifles were set to shoot reliably at a "few" ounces. So, here is the video of one of them, my Airwolf MCT after a few tweaks to the trigger. It's primarily a bench / pesting gun at the moment. Again, expand the video to full screen for best viewing. This is two shots both breaking at 3.2 ounces

And for an even better trigger (Thank you, Mr. Zasadny) here is my Daystate CR-X field target gun. Its shots break between 1.9 and 2.1 oz.

So, how did the Impact do after coming back from AoA? Video below.

MUCH BETTER! They managed to get rid of most of the trigger travel and it is now breaking cleanly at 12.8 and 12.9 Oz. With just a little travel and being under a pound of pull by a few ounces, I'll definitely say it is now performing in the match trigger range. It's 4x the pull of my Airwolf and 6x the pull of my CR-X but is definitely completely usable on a .25 hunting gun. Would I like it lighter for a 100M .30 benchrest gun? Yes, but more on that later.
That's it for today. Next up, a check to see if the Impact is under 30 ES on fill from 250 to the regulator.
