NM_P99,
I was at the gun store the other day checking out some other P99's. Every P99 that I tried had the flex also. You may not be looking in the right place. You should be looking at the right side of the frame where the warning is molded in. The majority of the flexing is during DA pull right at the words "warning read." Try a slow DA pull while observing that portion of the warning. It should be minimal at best but all the ones I've seen do it. HTH
