If I remember correctly we got issued a well used Walther PP, per trip over Iraq, given back and put away into shared storage. So these weps were passed around and knocked about and not fired or maintained by us. I have no idea what maintenance they got, maybe these were the same PPs that were there for the entire duration of the No-Fly Zone and Telic!
Back in the UK training consisted on one mag per year, so yes it was an almost pointless exercise. In my entire time in I probably didn't reach your rounds per month, using pistols anyway.
