Just finished an 07e class with Tom
I just finished a class with Tom. I can say he has made me a believer of the thumbs forward grip. I was a consistent low and left shooter. I learned the method from him and he said "trust me do it this way and your shooting will improve" he continued with "Its only A way not THE way."
I will say that with the performance I have seen with this grip it is "THE WAY" for me. I have now tried this grip with all of my handguns each with the same outcome. I am now putting my shots into 1.5-2inch group on command. Prior to training with Tom I trained with LE in North Carlina, USMC, and the US Army. Each had their strengths and weaknesses in their approach but the thumbs forward grip had a faster more drastic change in my shooting than all the other training I have had combined.
I highly recommend that you check out this training. Even you experienced shooters can pickup some useful skills from this excellent training. I congratulate Tom and Golden Seal Enterprises for putting together such a valuable training experience. Basic Handgun / Advanced Handgun.
