This is a superb holster that fits both my large frame Glock 20 and 22 and my other pistols, including a sub-compact. In addition to the seat bases, I also stick to the outside of the van while I’m sitting under the awning, or if I’m prepping my backpack or fly rods at the back. The magnets are strong! This is a seriously great holster for vans or any other metal surface you can image. I highly recommend this unique item.
