Thanks for the insight Roadworthy. I contacted Umarex in Arkansas. The T06 trigger and piston total $133 incl freight. I was raised by a man who grew up during the Depression and who would have made his own light bulbs if doing so would have saved the family money. Some of that rubbed off on me. (You ought to hear my daughters yell.) $133 is a lot to pay for something I already own...a trigger assembly. How good can I make the T01 with the right work on it? I am not opposed to tearing it apart and investing the requisite time to improve it if doing so will yield significant improvement. $133...That would go a long way towards paying for a 54 that has a T06 already in it. If I could find one in .20 the discussion would be over. If it was your money what would you do?
