These holsters are not made to accommodate a threaded barrel.
Not true. They can fit a comp, but it has to be a pistol length that’s smaller than the holster is designed to support. All G19/17’s will fit in the G34 holster. Lots of videos on this with comps and lights.
Wrong, they fit smaller pistols with comps and lights. Do research.
No, the red dot compartment is too small to accommodate the larger Trijicon SRO. Safariland does not currently offer a duty style holster that will accommodate the SRO.
