The 508T arrived today and now sits on top of the Echelon. Cowitness of the irons is very good. They sit low enough to give the shooter a generous amount of unblocked window, but sit high enough that the tritium dot and ring on the front sight is completely visible. I’m still planning on shooting it during at least one stage tomorrow evening at my multigun match. I have the 2x mags that came with the pistol, and I’m still waiting on 4x 17rd mags. They are supposed to arrive tomorrow, hopefully before the MGM, but if not the 2x 20rd mags should be more than enough to get through a stage. The Safariland hasn’t even shipped, but the PHLster is still a very good option.
