Interesting,
I've been testing some IMI produced 9mm ball ammo in several P08's, some fellow shooters also tested it in P08 and P38's. We found no difference in feel and recoil compared to, say, 9mm 124gr GeCo (club standard) or 9mm 124 gr S&B. In fact, it had more in common with the GeCo and felt a bit milder than the S&B.
This particular ammo is being used by the Dutch army in the Glock 17 service pistols without problems.
