Chuck, the trigger on the Parker was wide, the web between the double triggers was removed and the trigger fit in the resulting recess. You would think that Ithaca would have changed the selector indicators to a more factory look instead of just stamping the letters in front of the safety button. The Miller on the Parker was very reliable and use of the safety for barrel selection practical although I rarely changed it. Robert is right about the stock fit being critical for trigger operation, but that is true about most single triggers that I have seen. Be glad you don't have one of the non-selective triggers that Ithaca used on the NIDs. It is a Rube Goldberg device and made of stamped parts.
