Just received my new Guns and Ammo, while flipping through the pages i noticed that HK, Kimber, and Beretta all have new polymer guns out. All three have the removable back straps. At first everyone i talked to joked about the removable back straps, now since people see how useful it is, the copycats are coming out. Taurus even mentions the M&P back straps in their new 24/7 ads, claiming their grip is far more superior. It looks like the people at S&W were way ahead of the game in regards to this useful tool.
