So, I bought a couple different safariland ALS holsters for P226's when I used one for work. I hadnt messed with them in several years but needed an rmr compliant holster for my M&P HD 2.0 with threaded barrel. It took about 5 minutes with a dremel, another 10 minutes with a heat gun and 30 seconds with a drill to relocate one side of the thumb break. Voila! A perfect fit, it turned out really well if anyone needs to make a holster their 2.0
