That reminds me of a Glock I once had. It was a 17L and had the long slide with a port in the slide, however the barrel was solid all the way out.

that makes no sense to do at all. The barrel should've been ported too. Possibly an amateur hack job on both the barrel and slide, so the previous owner rebarreled it(or completely misunderstood the reason for porting and just ported the slide). either way it was not a factory option back then and no reputable gun shop would've donr it.

My Glock 34 has a similar hole in the slide and no barrel porting. The hole is designed to lighten the longer slide and has nothing to do with porting of barrels.

Makes sense. My training and familiarity is with the standard length Models 17 and 22.
