I think you are being smart using Glock OEM parts on a defensive pistol.  While a defensive shooting may never ever come up, if it does, the police will take our handguns, and those handguns will be checked over closely.  Depending on the attention to detail and knowledge of those checking them over, non-OEM parts, especially in the fire control linkage, could bite us in the butt very badly.

Honestly that's why I don't quite get why many Glock guys replace their triggers with aftermarket triggers like the Apex.  It's different in, say a 1911 other pistols where the trigger is a single part that doesn't affect trigger pull weight, but as you know of course, TJ, a Glock trigger is a multi-piece part that includes the connector, which specifically affects trigger pull weight.  We don't want to give a prosecutor any fuel to flame the fire he might want to burn us in.
