I have a Stock G17. I have polished the internals, and turned the rear sight around (because I dont like the |_|). There is not much I can do and still stay legal for the SSP class. However I would like to change some things with the trigger. I plan to put a 3.5 connector, however, is there more I can to to make is short, sweet, and smooth? I've considered Hiene sights also. Any thoughts or suggestions.
