I've read that the VP9 rail is rated to hold 5oz ? I also read while looking at surfire X400 laser light that they weigh 5oz.
I haven't found a rating for the P30? I know the VP9 rail is longer and the front is different from the P30S I have.
How does HK VP9 rail rating compare to M&P 9 and G17 ? What are there ratings?
Anyway If my P30 rail was rated to hold a max of 5oz I don't know if I would want to mount a 5 ounce laser/light ???
