For me I prefer the bd model with no trigger mods. The d/a trigger pull even in the half cocked postion seems quite heavy enough to carry chambered safely.
If trigger mods are done as many do, I would prefer the safety model to carry locked and cocked. D/a half cocked modded triggers might be too light in a bd for my preference.
I have a rami bd with no mods and a 97b that I plan to upgradede to an "E" conversion eventually. Either option requires consistent practice to handle safely.
A problem can be if one uses both options for edc rotation. The size difference in my rami vs my 97 would probably help me avoid any confusion.
