This is somewhat confusing to me, If I have a Gen 4 Glock with the dual coil system and I want to change the recoil spring to 13 lbs or 15 lbs
is the only way, to buy a Gen 3 recoil guide rod, with a Reducer/converter + buy 13lb Spring? Is there such a thing as a Gen 4 Dual Coil Assembly with already a 13 lb spring installed?
