I bought the Miami Classic holster for my Glock G17 and G45. I later bought a SIG P365 which has become my everyday carry handgun. I switched my original harness to my holster and magazine pouch for my SIG and ordered the 2 1/2” harness for my larger handguns. By using the larger harness it can distribute the weight better for the larger handguns. Always been happy with the Miami Classic.
