I'm interested in good night sights for the P99. I've seen some on the web and while I like the looks of what appear to be more standard sights from Trijicon, Inc. or Meprolight, I really like the idea behind the ones from XS Sight Systems. Pic below...
Can anyone share experience with any of the above and how 'easy' was it to install on a P99? Anything to be aware of when replacing stock sights?
Oh, one side item, is it true that even if you get an original, NIB P99, the sights are not the same as the models sold outside the US. If so, whats up with that?
Thanks for reading!
