Couple of good choices, and tough to pick between. Both should be easy to conceal, both have a life time warranty, both carry the Taurus name. The semi offers almost 3 times the ammo load capacity, it also allows for the pistol to have the magazine loaded but no round chambered ( a safey factor plus), offers a manual safety should you choose to keep a round chambered (a safety factor plus).
The revover offers the simplicity of operation, however if a problem does show up if is seldom a DIY fix or repair so it will need to be sent in for warranty repairs. While is used to be there were almost never any issues with a revolver, it seems to have become an issue that has come up more often as of late.
The one problem that does get mentioned form time to time anymore is some people as they age may have a problem with grasping the slide and pulling it back to chamber the first round. Or in an emergency their spouse may have the same problem. Where as the revolver is a grab, point and pull the trigger simple to fire get it done matter.
If this were months ago, I would have directed you to the Taurus PT911 over the 809, but then I like metal over poly pistols. But finding a 911 would be tough to do anymore.
Think it through add up the plus and minus, then go for what you feel would fit your needs and comfort zone.
