When I sold Implus implants it always amazed me how people were only interested in the "gun". Every question that I got was about the gun. Never about the science behind the implants or their effectiveness. I get it that if you are implanting 200 head a day it is important for the gun to be easy to use, but I never thought it would be a deal breaker.
If you have to switch implants contact your local rep. and they will have a trunk full of guns that they will give you.
