I purchased Don's Delrin syth trigger for the I-frame. Its very nice. I did a little modification to it, added magnets and did a few other little things. Its a great trigger without having to mod it. I've been able to shoot faster, its easier to find a sweet spot on this trigger than on the stock I-frame trigger, it looks great. What more could one ask for in their trigger??
Don was very responsive, and a great person to deal with all around. Best of luck in the future Don!!!
