Welcome to the forum Dueeast!
The range master told me during breaking in of my CW40 that the poly frame does have some flex to it, which helped explain why I never had problems with metal framed semi's but the CW40 was causing some problems. A minor change in grip with my wrist more in line with the pistol seemed to cure the issues I was having.
