Porting your barrel is a great option to reduce the muzzle flip on your firearm resulting in a much flatter shooter. Allows for faster follow-up shots without adding a threaded barrel and comp. Obviously if you are getting your barrel ported you'll need to have your slide ported as well so the gases can escape.
*Typically there won't be a need for a lighter recoil spring but in some cases a lighter recoil spring will be needed.*
