I purchased a Model 66 with 2.5 in barrel last week as well as some 5.11 tactical covert casual shirts and am in the market for a holster. I would like to carry in the 4 o'clock position either IWB or OWB. Any owners out there with experience carrying a 66 or similar model feel free to chime in about what works and what doesn’t. I look forward to hearing from the experts.
