Yeah, but you have to admit that the P7's chamber loaded indicator is more useful. There is no doubt whatsoever with the P7Mx. The Mx can be checked by touch or sight much more easily(the funny thing is that I never trust it anyway.
--I always look for the brass). I remember my USPs' chamber loaded indicators were like the Glock will be with the upcoming change--and I didn't find it usefull at all. Perhaps I'm just spoiled by the P7's little extra touches.
