If you are going to open carry, use a retention holster. And learn how to use it properly so you don’t shoot yourself in the foot.
A level 3 retention holster (or better). In which case, your ability to quickly draw your own weapon is limited as well.
I like the Blackhawk Serpa for my SIG 229. I use a shoulder rig foy my Glock mod 20 and my S&W 629.
