Apex and Galloway both offer triggers that just replace the factory trigger without changing any other part (for people, like me, that just don't like the hinged trigger).Why of why would someone use/ carry/ deploy/ operate a handgun that is stated as defensive/ mission critical with an APEX trigger in it? OEM setup on Defensive Guns, ONLY. Apex, Dynamic, and the like are made for Competition use. there are so many reasons to never do those things...
O.P. doesn't say if it's just a replacement Apex trigger, or an Apex trigger kit (that changes several other fire control components as well).
