I just picked up a P99AS this last weekend. I think it's an '04 model - it has the standard picatinny rail and no hump in the trigger guard. My wife and I took it to the range and found out it aims high compared to our SA XD9. Does anyone here shoot both a P99 and an XD9 that can recommend which front sight to install on the P99 to achieve a similar point of aim to an SA XD9? I'm going to make a trip to the indoor range later this week since it's easier to see what I'm shooting at indoors with the red targets.
