.35 to .45. Either would work but I prefer patches that fit the bore tightly to help clean out crud in the grooves/chamber. If by chance they're a little snug you can always trim them down whereas you can't make small patches bigger unless you double them up and that uses them up twice as fast.What size cleaning patches should i buy to clean a glock 17 gen5? 9mm Looking at the bullet diameter, a 9mm is .355 inches so does that mean i buy patches that are .270 to .35 or buy .35 to.45?
