They are out there,,,,. The vast majority of active units, never carried an issued revolver.
Contrary to the 4th Edition, they were all marked & chambered in .357. Only .38+P SJHP was issued. Though some units might admit to carrying non-issue rounds,,,,,,. In some areas of the state, it was not uncommon to be the only Troop on duty in the entire county. All worked (and still do) in one-unit cars.
They were issued with Pachmayr "Gripper" grips. Only choice with or w/o covered backstrap. Other grips were not allowed.
The S&W 681 was the last issued revolver AND the only one OSHP-marked. All subsequent pistols; Beretta 96D, SIG 226DAO & SIG 226DAK (all .40S&W), and current SIG 320 are OSHP-marked. The DAO's & DAK's are out there in the secondary market. Either from the Troops that bought them or those that were not purchased & went for dealer trade.
