For some of you old (er) guys who have carried IWB for a long time. Do you swap your holsters after you feel like the animal skin has turned into a dead animal skin. With the advent of newer plastics I don't think this would be much of an issue if you have gone plastic, but I prefer a animal skin IWB for the comfort. But for the guys who have carried in Knulls or Sparks for a long time after a while does the COW or Horse start to degrade? I have carried an IWB for about 3 years now and I'm noticing after a while the animal hide starts to get a little frail. I carry every waking moment of the day in generally an M-TAC( already replaced the clips once due to external pinning outward) or a sparks depending on how I'm dressing, but the M-Tac sees more use since I'm not a Jacket guy. Plus the Hot summer weather of VA doesn't really cater toward a jacket. I'm a big guy 6 3 260 (excuse me horizontally challenged) and I do perspire therefore the COW seems to get flimsy faster then the Horse but just wondering if there was a rule of thumb for you older crustier (jk) guys who have carried for years.
