When multiple agencies have ditched the platform because of repeated problems (cracked sear block housings, failure to fires, constant rusting issues, etc); that, to me, points to problems with said platform. That is why the POS comment was made. I could also cite that the slide stop is too large, the mag release lever and how mags dont fully drop free, the poor grip angle, etc. Of course those things are personal preferences unlike the mechanical issues I started this post with.
It is great that you like the SW99. However I, along with over 1,000 other police officers (from one agency alone), dont think they are fit to be a duty gun.
