Wore mine for 12 hours helping tear off and reshingle a roof. The only hotspot was the rear sight and where the light was packing into my thigh. I was using a phlster floodlight so no sight protection because of rds cut and it had a tlr1 attached.
Since i can't get this cut for the rdo I'll get something dedicated and with sight protection. But i have to say the slick beretta's carry well
