a lot of the pocket carry problems lays in the type of pants and its pockets, more so than the gun and rig its in.

casual type pants with a slash side entrance pocket lend themselves to pocket carry better than top entry "blue jean" style. of course the depth of the pocket is vital as is the diemension of the pockets top opening.

many pockets have different shaped bottoms, i.e. squared, rounded, tapered......so holster selection is important to get a good match.
