When you get a chance, post the model number.
Several options for trigger, thumb safety, optical cut, front serrations, etc.

Took some effort for me to get all the protective coating out of the barrel. Not sure why but S&W does not like solvents with ammonia.

Try loading a full magazine. You might need a speed loader. (My 4" 9mm takes only 14 out of 15.)
Then, with the slide closed, try inserting the mag. I would have to force the mag to lock. (Luckily, I only have 14rds. )

Just for fun, try releasing the slide with the slide catch on the right side.
(I am left handed and the right side is much harder to release than the left side.)

Not sure which trigger it has, but if it feels 'gritty' their are some options to improve it. It is supposed to have a longer take up, but I never notice.

Then Enjoy: great grip and low bore ratio = flat recoil, on target, slim profile.
