I've had one on my P-32 for about 6 Mos. Don't like awkwardness of adjusting the point of impact (have to adjust mounting screws on the device) and, yes, it's not as strong as many.
OTOH, it breaks up the outline of the weapon, so it prints "wallet" in my rear pocket, rather than "gun." With the almost total lack of sights on these litttle monsters, and the fact that mine points way below my natural point of aim, I'm very pleased with mine. Would let me take a head shot up to 15 yds if necessary -- something I wouldn't have even thought about trying before I started using it.
