Aging eyes...best friend and I have decided to put red dots on most of our carry pistols. He has a Sig 226 (357 Sig) with a slide milled for a Holosun 508T with the green reticle and has two 407Ks ordered for a Ruger LC9S pro and for another Sig. The 508T is really nice with the 32 MOA circle and 2 MOA dot. It is FAST.
I have a Sig P320RXC with the Romeo 1. The Romeo 1 is a good, solid sight. I do get some “flare” at times if I do not take time to find the dot. It cowitnesses with the BUIS; if I use the BUIS to find the dot, it is quick and very accurate. Not as fast as the 508T with the 32MOA circle...need to practice.
I had my Sig P365 milled for a Holosun 507K; would not go with the polymer Romeo 0. I think this will be a really awesome combo, expect the 507K in early May.
I have a Glock 30S that I am going to mount a DPP on. I will use the mounting plate; I think this will also be a good combo. I will post range reports next month.
I will argue that the romeo handgun sights are in no way good sights, especially for anything other than toys and range fun
