1). RIA 1911 officers compact with tritium sights for low light. This firearm was also modified and tuned by Lou Rousso with a throated chamber and polished feed ramp for reliable feeding of personal defense ammo.
2) Carried primarily in a horizontal shoulder rig. This one by El Paso saddlery.
3) The firearm is narrow due to the single stack mag and short enough to be carried horizontally.
The rig allows it to be easily covered by light clothing worn untucked or under a light jacket.
Horizontal holsters allow for unmatched access when seated. Especially in a vehicle.
The rig and firearm combination is important however. If this firearm did not have a separate safety, grip safety and exposed hammer I likely would not carry it horizontally.
Carrying a DAO in such a rig might be problematic.
With the 1911 platform, however, the firearm can be put into the rig safely and the strap over the exposed hammer offers the best possible protection against negligent discharge.
Draw is swift and consistent in nearly every body position.
