Doesn't work for all m&p's - Ameriglo M& P Front & Rear Sight Tool SWTOOL12

I like the M&P and have several, including an M&P Pro I shoot in competition. While the tool works great on standard 4.25" M&Ps, the 5" slide of the pro leaves the front sight sticking out beyond the front of the tool. I changed the stock sights on my wife's standard fullsize M&P for TFO's, and it couldn't have been easier. Pop them off, Pop them on. However, the regular M&P and the M&P Pro utilize the same frame, and same guide rod and recoil spring. What this means is that the part of the slide below the muzzle that retains the guide rod and recoil spring is 3/4" longer on the pro. This metal part hits the tool and leave the actual sight about 3/4" in front of the RAM.

The other thing I thought was odd, is that, according the instructions, the proper orientation of the tool is to have the lettering facing AWAY from you. So, the way to tool is pictured is actually the back of the tool. While it didn't affect function, it is just odd to hold the tool with no lettering towards you.
