I ordered the trigger via email order, and received confirmation on order next day...I waited a week and no trigger. Called IPB and asked what was going on, they told me there was a problem witht he delievery and alot of packages had came back to shop, and mine was one...To fix it, they sent the external adjustable trigger (instead of the older style that I ordered) and next delivery.
Took me an hour to get it installed and adjusted (this was the first time I had gotten into the grip and frame of the marker so I wasn't so surre of what I was doing). Installing it was easy enough, and adjusting it was easy too.
To the guy who said his two fingers didnt feel comfortable (that he preferred the Double finger trigger instead of the blade) try it with one finger . I rest my trigger finger(middle one) knuckle about 1/2 way down the trigger with fingertip on the tip/end of the blade. I find I can pull faster that way than with 2 finger or even fanning it.
Get it its a good product, and obvious upgrade to the stock, and the guys at IPB are great.
I just wish I had gotten the Vision set-up on the marker, I HAVE outshot the 12v with this trigger and broken balls due to the gun trying to cycle too fast. Oh well.
