is nine ball recoil spring guide and plug for 1911 is made by casting or CNC? what material is it? steel or aluminum or pot metal? thanks
any suggestion on a good or the best rec spring guide and plug? will there be any performance difference between buying cheaper ones like guarder and expensive one like prog4 guide/nova plug?
