Most handguns will fit within the Konig Go except for larger caliber pistols, "extra-large" handguns, or longer-barreled revolvers. The Go’s interior measures at 8.5” L x 7.25” W x 2.13” H. If you’re unsure your firearm will fit, we suggest drawing the stated dimensions on a piece of paper, then placing your firearm on the paper. As long as the firearm doesn’t overlap, your firearm will fit!
