Update. Got a chance to shoot the ones on my list. Picked up a Glock 43 after work yesterday. I was originally leaning toward the glock and didn't experience anything I didn't like with any of them shooting so glock it is.

very reliable and the trigger can be changed up easily if you don't like the feel. It's good that you had a chance to try a few first. Glocks just don't fit my hand plus I don't care for the plastic guns but that is just my personal opinion so I dumped mine. Shoot it and find a good holster!

Any recommendations on holster would be appreciated and where is a good place to get them?

I prefer a crossbreed supertuck "in the waistband" holster. It is very adjustable for angle and height. I have only seen them online but I have seen decent clones at gun shows for less $$$$.

JM Custom Kydex G43 Quick Ship

JM Custom Kydex makes the best holsters I've ever used. Not all holsters are created the same.... you might be able to save a few bucks with someone else but it won't be the functional equal to anything JM makes. Hybrid holsters are too damned hot, and the retention really sucks. At some point, you will take a fall and you don't want your gun laying on the ground when you get up. Don't ask me how I know.

I carry AIWB but wouldn't recommend it for beginners. I also use one of his regular IWB like the provided link, with a belt clip. It's quick to put on and take off if I'm going into places where I can't carry.

I use a Stealthgear Revolution with my g43. I've been happy with it.

Old school. Carry a Colt Detective Special most of the time.

I got one for my G23 from East here on the forum, haven't seen him post in awhile though.

Get a slip in pocket holster. The 43 is plenty small to pocket carry. It’s 100x more comfortable than IWB. I carry an lcp in my pocket every day.

I carry a Kahr PM9 in a Crossbreed Minituck. Very very comfortable.

Crossbreedseconds.com is their outlet website. Great deals on their holsters

I think you should get that.

Never shot the 938 but a SIG 239 has been my CC for damn near 20 years. I'll carry it open and concealed, also carry a 226 but it's mainly an open carry due to it's size. What I want in a CC is conceal ability meaning it has to be small, thin and shorter in the grip, weight is the least of my concerns. Glocks are good and reliable and I would recommend both but I'll carry a SIG. Nothing against Glocks but I just don't like plastic pistols, none of them. With that said you'd be hard pressed to find a better pocket pistol than the little KELTEC 380. It slides in and out of the front pocket like butter and goes bang every time you ask it to. I prefer a DA/SA over a SA but that doesn't mean I'm getting rid of my 1911'a or my Browning Hi-Powers.
