Today I tried the Arsenal Molds 359-130-RF in my gen 5 19.They are sized to .358 with RCBS 80008, seated 1.070 with 3.8 grains HP-38. The gun is factory stock in every way and the rounds plunk quite easily. Accuracy is about the same as my other 9mm pistols with this load. Upon cleaning, I was pleasantly surprised to discover way less fouling than I expected. It's not uncommon for this load to leave little streaks of leading near the muzzle but there was none whatsoever. Love this pistol, best Glock has ever made!
