I am kind of new but I have read most of the posts on here. I am thinking of getting a p99 QA .40 with the .357 sig conversion, hoag slip on rubber grip and meprolight night sighs. I am just curious about the p99 QA. I was thinking were can I get that QA with all german marking? Does meprolights offer any other colors rather then all green? Also when I do get the .357 sig coversion, will I need a gun smith to install it?
