These are made from 1/4" thick 6061-T6 aluminum. They offer both vertical and cant adjustment. The mounting bracket has mounting options for Bladetech, G-Code, Comp-tac and Safariland all on the same bracket. I ship these with 1/2" spacers that put the gun right around 1 3/4" from the inner belt. If you would like optional 1" longer hardware to take advantage of the new Limited/Open rules for distance, just let me know in the comments with your purchase. These are legal for the Single Stack rules and allow the 1911 to drop down to a much more comfortable position. I use Allen head hardware on these. The belt slot is cut 1.75" to easily accommodate competition belts. If you need a hanger for a 2" belt just let me know.
