I agree with kjtrains and Reinz, here. Training and technique are things that we can improve. I think it is very promising.
I have no doubt that an R45 would be reliable and effective. It's true that not everyone will be able to shoot it effectively, but to be quite honest, it's the "know-it-all" shooters that are the problem. Those willing to learn will adjust and become proficient.
I didn't mean to sound negative. Actually, I'm quite enthusiastic about the R45. I know that Rohrbaugh will create a exceptional product and I will ensure my technique is up to the challenge of handling it effectively.
