I've zero experience with HPG, but that Recon Kit does look intriguing. It also looks REALLY bulky which is one reason I can't stand Alaska Guide Creations harness.

I am all about FHF harnesses....have three of them. I also have several of the Razco holsters like Mtwarden, and have no reason to veer away from that system. I carried a .454 Casull and those 15X Meoptas when getting my WY ek out this year, and it was way more comfortable than I thought it would be even with so much weight.
