I chose my style of carry based on my LEO training. Never carried before recruit school. There we trained strong side, belt, open, of course.

When I bought my first off-duty revolver I carried it strong side, OWB/IWB, about 3:00-3:30, as I carried my duty revolver.

Now I sometimes carry with a shoulder holster, but that's mostly when in a vehicle for long distances. Very, very rarely pocket carry. The vast majority of the time it's OWB or IWB in the same position I was trained initially.

Yes, I did receive plainclothes carry training as a LEO. That training allowed only strong side belt....OWB and IWB. Period. No cross draw or shoulder holsters were permitted for plainclothes duty. One could place their holster just about wherever they chose provided it was strong side, but toward the front (appendix) and toward the rear (SOB) were strongly discouraged for the obvious reasons.

Be safe.
