I emailed Chad about the olight Baldr S and included pictures of the light position. Please stamps or no markings on the outside of the holster. The FN 545 Tactical comes with suppressor height sights from the factory. Per Chad, I did check the "TALL SIGHTS" box". To be clear. the firearm has the factory sights.....see pictures. Any questions, call 7724860221. Regards, Jim
