Great advice guys thanks!! I'm going to be shooting straight lead and pc bullets out of my glock17.Ive read pros and cons about the subject,some say don't because of leading and the polygon barrels,others say as long as you lube them,resize them(I have a Lee .356 resizing die)and check/clean the barrel every 50 rounds it should be OK.I might just buy a wolf replacement barrel also.Any and all advice is appreciated.
