My local range had Jerry for a demonstration a couple of years ago. He is indeed very friendly and incredibly fast. He not only fired his standard show with his S&W 625 and 627, he also had several other assorted guns on hand as well, both revolvers and autos. Same results !!! With an auto, he stated that he was limited by the cyclic time, and YES he wa fast with an auto. On the other hand, with a revolver being a purely mechanical linkage, he could make them run faster. He even had the range bring out their "cruddiest and worst" rental gun. He was also fast and accurate with the rental too.
I got to chat with him for a few minutes afterwards. He is a very nice man. I asked him if he used reduced loads, lightened trigger, etc. as I noticed that he had virtually no muzzle jump when he fired. He related that he controlled the recoil. He told me that he uses standard factory loads (I could plainly see the boxes of ammo the range provided. S&W pays the tab as they are his sponsor). He said that he does much of his own gunsmithing as he is on the road a lot, and he has only slicked-up the action for smoothness. He futher said that he holds a high grip on the frame to help controll it. The hammer just barely clears his thumb-hand web. He uses cornstarch on his hands as he does want to have a small degree of sliperiness on the "Micilek" grips that he helped design and use. These grips come on the S&W 625 'Jerry Miculek special' and are availible from S&W. I asked him how he got to be so fast. Was it a God given gift or did he develope it over time. He answered that he started shooting years ago at normal speeds and just worked his speed up over time with lots and lots of practice.
As I left him, we shook hands. Where I wear a size 8 to a 9 glove, his hands were close to the size of a baseball mitt. He has a very powerfull grip.
When I got home that day, I tried to dry-fire one of my revolvers (after verifying it was unloaded of course) at a fast rate. There is no way in the world that I could pull the trigger as fast as Jerry does. That was with an unloaded gun. He does it with live, full loads, controlls the recoil and stays on target, usually head shots.
For anyone who might think that Jerry's shooting is a fluke, trust me. He is the real thing. His skills were developed over a lifetime of shooting. If you ever have the opportunity to see him perform in person, by all means, go see him.
