The issue, as I understand it, gets considerably worse in cartridges starting with .4 and ending with 0, although 9mm and .45 Glocks have kaboomed as well. The polygonal rifling can lead up in a way that narrows the bore, spiking pressures. When combined with Glocks' partially-supported chamber... bad things can happen.PBR wrote:this is scary -- i have shot hundreds and thousands of swagged lead through several glocks have owned -- never noticed any issues with them but they were cleaned very well after every trip -- barrels look as good as first day bought them -- maybe have just gotten lucky on them so far, was told by many no problems with lead but just to clean them very good -- as said though I might have just gotten lucky so far as they werent no glock experts either
