That would be the "duty pistol" competition or are you referring the "semi auto 1500 round" the latter is the same course of fire as the basic revolver 1500 round (150 rounds @ potentially 10 pts each) Lots of fun!! The duty pistol part of the competition is also 150 rounds with a cpca approved type of pistol and a level II (same as level III in the US)
In the 1500 round there are a total of 48 rounds fired at 50 yards from the sitting, prone, and left and right barricade position. the other 102 rounds are fired from 7, 15,and 25 vards from various shooting positions. OP, don't know where you are located but if you are in my area, I'd be happy to set you up as a guest at our monthly practice competition.
