It feels nice in the hand, the trigger is decent and breaks at 90 degrees. As out of the box striker fired triggers go I'd give it a pretty decent score, however I feel like the triggers on my P10C and P10F blow it out of the water, but it's better than my Shield and the other M&Ps I've shot. Don't have any trigger time with a glock so I can't compare them.
The front sight is very easy to pick up and I thought were overall excellent, haven't seen how bright they are yet as they are tritium sights (front blade is FO and tritium vial). I actually liked them quite a bit. It does have an optics plate but I'm kind of on the fence about adding a red dot since I thought the sights were really well done.
It came with two 17 round mags and I picked up more act-mags from gregcotellc (way cheaper than the sig branded ones) and they worked perfectly. Ran about 10 mags through the gun total and then had to call it quits since I only brought about 250 rounds with me. Ran a couple mags through my other full size polymer guns as well to get a baseline and the Sig performed just as well. Though I am still partial to the CZs more. I will say being used to the lower bore axis on my CZ guns there was more muzzle flip than I was used to at first, not a ton but it took about a mag to adjust for follow on shots. Overall pretty pleased with the purchase.
