I read allot but rarely post. Some pics of recommended grip positioning for the p30 would be much appreciated. I rented a p30 at my local range and had issues with the slide locking back with my accustomed grip from shooting my cz97b which is identical to how most people like to grip their 1911's. Thumbs down range riding the thumb safety. What is everyones philosophy about hand positioning? Does an ideal tactically correct hand position exist that should be applied to most pistols that a majority of specialists teach? Does the gun dictate hand position and therefor through trial and error you should find what best works for you? If so would you have a different grip for different pistols? What steps do you use to formulate your pistol grip when approaching a pistol that you have never shot before? Also discussion on the HK45 is welcomed as one day I intend to own both excellent HK pistols, the P30L and HK45.
