As time passes you will become a member of the 'holster club' like most of us who have boxes full of them. I personally don't like the dirty harry rig, but, I used the Miami vice by safariland for many years-very comfortable and hides well. Now retired i usually carry IWB using Kirpartick leather with a renforced opening for easier draw and reholstering, after too many years I tried but don't really like "plastic" holsters.
As a reply to your FF, I was also a volunteer FF and full time sheriff's sgt. On one call [accident] one of the drivers was very DUI and trying to leave the scene, so I formally arrested him-handcuffed him to a non moving object, then as a FF I worked on the injuried until a on duty sheriif arrived to take the "detainee" to jail". Boy did I get flack from the other vol FF. are you a cop or a FF? What was I to do? I couldn't let the DUI leave the scene. Anyway after 13years as a vol FF, I retired. and continued my regular job until I retired from that 9 years later. I will admit I was Pi sed, at the FF attitude, espically since I allways considered us as equals, working for the public. FF structures was fun, wood fires I hated. Cop work was great [except for court].
