I carry a S&W M&P 45c. I love my Overland carry vest but in hot weather not so much. I am not a fan of IWB when sitting in truck. My 45 has no safety and is cocked and loaded. For my vest, I just velcroed in place of their harness a pocket type holster to protect trigger area, works fine. Looks like they have a shield that would protect trigger area. Anyone have any experience with them? $80-90 to find out is a bit much to find out won't work. Thanks
