I have a Glock 35 that I use for USPSA that has a bunch of modifications: 1. KKM barrel 2. Grip tape 3. Dawson ICE magwell 4. Dawson sights 5. Trigger kit from Vanek Custom (breaks at 2 lbs) So which mods do I need to remove to be GSSF legal? Is there a required power factor for ammo or can I load up some super light .40 for GSSF matches?
