LWD Tungsten Guide Rod Assembly (with stainless back cap), item number LWD-GRA1923-Tg is a complete drop in unit. This fits all Gen 3 G19, 23, 32, 38 models. Special features include a heavier solid one piece tungsten guide rod to accept a removable 3/32 allen head tip. To make the guide rod assembly compatible with a Gen 4 model, a Lone Wolf Gen4 Guide Rod Adapter is required.  These combined features make the Lone Wolf Tungsten Guide Rod Assembly the most durable, longest lasting system available today.  

Lone Wolf Tungsten guide rods provide a decisive advantage for all Glock owners by providing an additional 70% weight increase at the front of the pistol versus a stainless guide rod assembly. This extra weight will help reduce muzzle rise allowing for quicker follow up shots.  Special features include a rigid Tungsten body that improves lock up by completely removing "guide rod flex". Used by Law Enforcement and competitive shooters worldwide, these guide rods assemblies will not not chip or crack like the factory plastic guide rods are prone to. Will not damage or wear the polymer frame and guaranteed to provide a lifetime of reliable service.
