The P365XL is about the perfect size to concealed carry. Being a 12 round gun and being just long enough to get a full grip on but being slim enough that its light and thin on your belt makes a gun capable to be carried all day. Having a 3.7" barrel means the gun will get better performance from hollow points compared to its shorter barreled brother. The trigger isn't great - in fact it's mediocre. The ergonomics on the trigger are great - but the mechanical quality of the pull is really substandard. Everything else about the gun is really great. Magazines are expensive - so be prepared to spend just shy of $50 apiece. The optic cut is OK - but a lot of the small sights made for the skinny 9mms will cowitness with the front sight. It's a really great concealed carry pistol - I highly recommend it.
