I believe you will be very happy with a Timney 510. There are two trigger widths from which to choose. The standard 510 trigger blade is slightly wider than the factory trigger blade and may take a minute or two with a file to open the slot in the top of the aluminum trigger guard. This is very easy to do and not noticeable after installation. There is a thin blade 510 trigger available also that will not need any filing. I like the standard (wider) blade better but to each there own.
