This is my first post on here but been stalking the forums for a little while now. I currently own a XD9 Service, XD9 Tactical, XDm9 and XD40 service and love each one. I've been shooting steel matches with my XDm9 but wanted to get into IDPA as well. I have some money aside and wanted to send my XD9 Tactical out to springer and really turn it into a beast. So far my mods list includes: -Competition Trigger Job (2.5-3#) -Solid Guide Rod -Dawson Adjustable Sights (fiber optic front and target rear) -Barsto Match Barrel -Extended mag release -Grip Stippling My main questions were am I missing anything that anyone feels would be a good addition while I have it there? And should I just leave the springs stock or is a different spring to use where the gun will feel better? Also I'm debating between the regular front site height vs the raised front site-any suggestions? Thanks and input would be greatly appreciated.
