I have a G23 gen2 which is just now starting to show some questionable wear to the guide rod. What guide rod/spring combo is prefered now a days? Do i need to just order a oem replacement? I dont mind spending a few extra bucks on a aftermarket if its been vetted and is known to work well. There has never been any problem what so ever with this pistol if that matters. Not really looking to change spring lbs but my gut tells me that a ss guide rod would be better. I would like to hear what you gen2 guys have discovered.
