You can also shoot the 19 in CCP division (but not the 17). In CCP you can have aftermarket modifications (triggers, small magwells, Stipple jobs and such) but you are limited to 8 rounds.
You could shoot either in stock form in SSP division and have 10 round mags. In SSP you are going to be shooting against a bunch of G34s though.
I usually shoot my 19 in CCP, but have been shooting carry optics since they adopted it as a provisional division.
