If you are really serious you will disregard all the previous postings and go to
www.ironmind.com. This is the web site of the company that caters to professional stongmen, olympic athletes, and really serious amatuers. This company has numerous types of equipment designed to increase all aspects of hand, finger, thumb, and wrist strength. I GUARANTEE THEY HAVE HANDGRIPS THAT NONE OF YOU WHO HAVE POSTED TO THIS THREAD WILL BE ABLE TO CLOSE. No condesension intended and you will understand the truth of my previous statement when you go to the website.
In a world devoid of semiautomatics, a properly set-up Webley is the ultimate full-size self-defense handgun.
