The GBA+ thing is mainly about the trigger weight of our current pistol (12lbs) and its consequences for cadets and members with smaller hands or weaker grip strength. I'll let your piece together on your own who that is. If they're going to use it to get us a modern combat pistol with RDS and weapon light instead of the 30 year old completely obsolete junk we carry now that's cobbled together out of spare parts, hopes and dreams I'm all for it.
I've been following our RFIs and now the RFP closely since it came out, there's a thread in the RCMP forum if you want to dip into my musings on that.
So part of the GBA + that was done for the Canadian Army (and MP) pistol was measuring the hands of people and then having different size frames so that those soldiers (of all genders) can safely and effectively use the pistol if they require a larger or smaller frame than the standard frame.
