Go with whatever you prefer shooting. The size difference isn't that pronounced and if sh*t hits the fan, you'll want a gun that you can shoot straight.
Well in that case he should be looking at an m&p compact or a shield
Yeah the .380 is the reason I didn't buy a 42. When they make a 9 I'll buy it.I love the m&p 9s but I have to say I'm not that impressed with my shield, it doesn't shoot as well as I'd like and I hate the safe action trigger that's split across the middle. The new baby glock 42 is more accurate and more comfortable, but I just don't like 380s.
My next handgun purchase will be a G26. The subcompact offers more options for concealment than the 19. You can make the grip of a 26 longer but you can't make a 19 shorter.
I feel like another thing that doesn't get brought up a lot when comparing the G26 to G19 is the weight. I know it isn't a ton but the G26 is significantly lighter and I feel that makes it more comfortable for me. I carry both but when my outfit is more minimal then I tend to go with the G26. However, to what I said about less weight, there are also fewer rounds...Just my 2 cents.
Imagine you're 5'10 145 - 150 lbs, male or female and you'd like to carry iwb with a crossbreed style holster @4 o'clock
Glock 19 g4 or 26 g4
You want it to conceal well, not show through your jeans (into your butt!)
You also want the most effective weapon that will meet these requirements.
You can only choose between the two glocks.
Well there certainly should be, however that seems to be the prime motivator more often than not.
