I shoot it the same way as RBK: middle and ring finger on the grip, pinky wrapped under the bottom. We had our IDPA back-up gun match this past Sunday and I shot my P32. I was amazed at how quick it was and how easy it was to shoot it acurately. No problem keeping them in the IDPA target kill zone out to the farthest target, which was only about 7 yards away (back-up gun match, remember). Most importantly, the gun has been 100% reliable.
