Don't overthink it. A $35 Blade Tech or $40 Uncle Mike's is fine. Anything open top without extra retention doodads, cut below the ejection port with tension screws. CompTac, Red Hill, Ghost. There's no need to get an open race rig for a G17, especially for a noob.

Would you say gravity helps if shooting inward ?

It looks like there was a crimp issue. I lowered the crimping die very slightly, and the rounds started going in. I guess the die must have managed to back out after the last group of cartridges. I made 450 cartridges, and only the last 50, which came from the same box, had this issue. I didn't think there was any way for the crimping die to move, but it looks like I was wrong about that. While I was at it, I checked the sizing die, and there was a tiny gap between it and the shell plate, so I fixed that for next time.
