As first , I can tell you that I heard about heavy Vtrigger trigger pull.So I've upgrade my VSR-10 to 600fps ±1 and did it will all PDI parts, and while the PDI trigger box is near indestructible, the actual trigger pull is awful. It basically feels like the gun is on safety when you are trying to pull the trigger.
I was going to try find a Noobies M-trigger, but if your trigger can handle a beating then I figure why not give it a go. My question is what is the trigger pull like? I don't need it like Laylax where I can breathe on it and have it shoot. But say a 1lb trigger pull or so would be nice. Have you tried measuring the force needed to shoot?
I am currently running:
PDI Bore-Up Receiver
PDI Bore-Up V-trigger 2
PDI Bore-Up Premier VC Cylinder Set (Palsonite)
PDI SPR 380% Spring (570 fps)
PDI Hop-Up Chamber - Bore-Up - ER-Hopped
PDI W Hop-Up Bucking
PDI 6.05mm 554 MM Barrel
Second, until now I dont have trigger pull scale but I measured it DIYthis way
Results that I get are probably not so accurate , but really similar to that what Noobie measured on his trigger
This is copied from his post on airsoftretread.com
"The following data (lbs nearest 0.25) was recorded:
JG Stock 4.25 lbs
EdGI SP01 7.00 lbs
EdGI SP02 8.25 lbs
JG Stock 1.75 lbs (59% lighter)
EdGI SP01 2.50 lbs (65% lighter)
EdGI SP02 3.00 lbs (64% lighter)
** Three (3) pulls on each spring, average recorded."
So M-trig has trigger pull on JG stock 1.75 and I measured on my S-trigger about 1.77 .
1 lb trigger pull (or lower) you could only have on zero trigger. If you was satisfied with Noobies M-trig (which is not available) you was be satisfied also with mine trigger. I broke my M190 Laylax spring , so I cant measure it with higher upgrade. But it was pretty smooth trigger pull even on this spring.
