Is it ok to modify a G19 with Glocks extended mag release and slide stop and still shoot in the Amateur Civilian category.
Agree, must use stock Glock parts for these mods. "You may use any combination of GLOCK-produced firearms parts that do not result in a significant competitive advantage in the Amateur categories and are, in the sole opinion of the match Armorer, safe to utilize; such as the use of a .40 Auto GLOCK G-22 barrel in a GLOCK Model G-31. .
