About to turn 21 and need help deciding a daily carry gun

Like the title said, I’m about to turn 21 in two weeks. I’m pretty set on what I want but I want some opinions before I make my purchase. I’m looking at getting the Sig P365 X Macro for everyday carry but the only thing I’ve read bad about the gun is easy rusting issue, anyone else have this issue or was it possibly a bad batch? My budget is around $900 and I’m open to different suggestions. I’m 5’10” and 225 lbs (bodybuilder build), looking for something with a longer grip due to thick fingers but still able to conceal.Holster - Pretty set on getting the T-Rex arms sidecar. Open to more opinions on this too. via /r/CCW https://ift.tt/uSbNM19
