GREETINGS ALL: Am considering a new P89. Have read that the grip panels are a little more curved inward than on older P 89s. How do grip dimensions: width, rear strap to front strap,and "circumference" vary between P90 and LATEST P89. Since I have my P 90 for reference, I can make a realistic comparison using your P89 dimensions. Thanks.....Happy New Year all members. M g.
