I would agree with you Geezer ....its got the edge due to the lack of vertical lines at the muzzle and looks better for having the foresight right at the muzzle.
I recently replaced a fibre optic set up on a 40 which was annoying one of my club compardres.
Simply slipped out the fibre optics and let in some solid bespoke machined Black Delrin inserts.
The 1mm dia. Delrin for the rearsight prob best just using some black epoxy.
