M17 slide not returning to battery

Couple things. Did you lube the gun before shooting it the first time? Most guns don’t come from the factory ready to shoot. I’m not saying you can’t shoot it directly out of the box, but you’re more likely to get better performance if you clean all the oil from the factory out and replace it with a quality gun lubricant. The stuff that’s on there from the factory is typically a rust preventative, and not a lubricant.

Limp wrist is a thing. If you don’t have a good proper grip while shooting, you can possibly cause a malfunction. One easy way to see if it’s you or the gun is to have a couple other people shoot it and see how it performs. If someone else shoots it and it doesn’t malfunction at all, it’s probably your technique. If that’s the case, don’t worry it’s definitely fixable! If there are any instructors at the range you go to, get a quick one on one lesson and they can help you out with that. The local range I go to have a bunch instructors and they are always doing lessons with new shooters and it helps them out a lot.

Lastly, sometimes new guns are especially tight and need a couple hundred rounds to properly break in. Try different types of ammo too. For instance HK recommends 124gr for breaking in their guns.

make sure you have a solid, 2-handed grip. support hand wrapped tightly around the primary hand.

and that you're not doing the cup-and-saucer movie-style grip.

ETA:
when you say, the slide stays back, do you mean it's locked fully to the rear? slide-catch engaged? perhaps inadvertently?

or do you mean that when the slide travels forward, it doesn't go the last 1/4" into battery (lock-up)? if it's the latter, IMHO, that could be a combination of grip style, and gun new-ness. I have a relatively new P320, the fit is nice-and-tight, but during dry-firing, sometimes the slide hangs back about a 1/4", and a simple thumb press sends it that last 1/4" forward into battery. when live-firing, though, the slide is rebounding with enough force that this never happens with live ammo, for this particular new gun. I chalk that up to new parts breaking in, steel-on-steel mating surfaces getting to know each other better.

I have about 350 rounds through my 320-m17 and only had 2 malfunctions. One was fail to go into battery @ around 100 rounds and the other was fail to eject around 250 rounds. The fail to eject left the fired case in the chamber and tried feed a live round from the magazine. Both fails were with W-W 115 gr. I lube mine with mil-comm TW25B on the rails and slip2000 EWL30 for everything else.
