Are you referring to the OEM "-" connector that G34/35 come with? If so, I'm curious to know what the liability issue is...too light? If I remember correctly, the KY state police issue the G35 for duty.Yes, we have all those parts in stock. We do not charge to install if the parts are purchased from us, but per our contract with Glock, cannot install a 3.5 connector for you due to potential liability issues.
