Been using my MTAC for M&P Shield 9 for about 2 weeks now, and it's getting uncomfortable. Basically, if I wear it at 3:30 or 4:00 it prevents me from sitting normally/comfortably/with good posture in my car (which I have a 30 minute commute each way) and sitting at my desk (probably spend half my day, so about 4-5 hours). The holster pushes the right side of my back forward off the chair and makes it hard to sit up straight with good back support from the chair.
Anyone have ideas on how I could correct this? I'd be curious to know!
