Purchased a Gen 4 - G19, cleaned it and took in to Front Sight in Las Vegas. It performed great. I fired the first six hundred rounds through that handgun at the course and kept them on target with no malfunctions. I really like the mag release and smaller grip over the Gen 3 version.
Just picked up my new G19 4th gen. Gun comes new lubed with grease. How come you guys dont use grease like on the slide rails? Guy who sold me the gun said only use oil and he is a gunsmith?
