Hello

I’m trying to workup a decent way to shoot high volume for my 9mm. I shoot a beretta 92fs with conventional that I’m not worried about but I also would primarily be shooting most of the volume out of a gen 5 17. I know the official position is no cast no reloads by glock but I was looking for personal experience. I’m not against the idea of aftermarket barrel but obviously there is a cost there that would take a while to break even on cast for. Also if anyone had experiences with a specific aftermarket with conventional rifling I’d be interested too

TIA
 
I have shot so much lead through Glock pistols I couldn't even guess at a number. All I ever did was quickly brush the bore every 2-300 rounds. With proper PC done no brushing is necessary. Honestly though I am not sure it was for the bare lead in my experiences but better safe than sorry.
 
Make sure the bullets are sized appropriately and blast away. Although, in Canada, unless you cast, CamPro's are probably the cheapest bullet you can buy anyway.

Ya there is this. It’s kinda the crux of the question too because by the time I’d pay for a replacement barrel, moulds ect it’s a pretty high round count to be saving money over campro and free brass.

Everyone's situation is different. I shoot a crap ton of 9mm a year, and I'm super cheap, yet I still buy CamPro bullets. Why? Because I refuse to invest the time, energy, and money required to produce all those bullets. Would it be cheaper in the long run? Sure, but I already spend too much time reloading. Some might argue that loading 9mm period is a waste of time, and they might be right, but I've made peace with the time, energy, and money required to do so. You definitely have to shoot a lot of 9mm to save, but I do shoot a lot, and I do save a lot.
 
I have a KKM on my 10mm glock, I mainly shoot jacketed or plated but will be shooting cast powder coated through it this year. I went with the KKM to stop brass from being beat up in the factory barrels unsupported chamber, as well as being able to stabilize a heavy cast bullet. I don’t know if the brass life is the same with 9mm and the factory barrel as it is with 10mm but the bulge at the case head was noticeably there before I swapped the KKM in, there’s video of the glock polygonal rifling not shooting heavy cast 10mm accurately so for me an aftermarket barrel made sense in a 10mm glock.

The bulge/glock smile is gone, 10mm brass isn’t as common or free to pick up so I’d prefer to extend brass life as long as I can. If I was only shooting factory jacketed ammo I likely would’ve kept the factory barrel but I don’t regret the cost of the KKM, I’m not worried about blowing up my glock with hot reloads as well.

If it’s just leading the barrel you’re concerned with, powder coated bullets should solve that. If brass life and case head separation isn’t an issue with 9mm you likely don’t need an aftermarket barrel.

Thank you. This is essentially my other concern. I’ve never noticed any bulging in the brass I’ve shot but I’ve never looked very closely. I’m curious how others have found that

You won't. Glock 9mm don't have the issue with budging brass. They always had a suported chamber. It was really only issue with Glock 40 and other cals.

I was under the impression that all glock chambers weren’t fully supported, I just figured there might not be enough oomph in the 9mm to make it an issue, 10mm I can definitely say I noticed the bulge. I unfortunately never got around to buying a 9mm glock, I’ve never noticed a bulge in any of my 9mm brass for the pistols I own in that caliber either.

I’ll have to take a pic of some 10mm brass I picked up, once fired Fed 180gn. Factory box was in the trash and you can see the blue laquer on the primers, 3-4 of them have a pronounced bulge. Enough that I set them aside, not fired out of a glock from the look/shape of the firing pin strike.
 
Pretty apparent in person.

Umm guess I was wrong. Never had an issue loading 9mm, and running into issues of any budging brass. Might see it if someone running 9 major but doubt they're using a stock Glock barrel.

Ran like 3k of x metal coated bullets in my Glock.

Guess 40 and 10mm are the most noticeable. But dad runs 40 cal Glocks and never heard him having issues.
 
I have been shooting lead out of my Glock factory barrels since 1992, long before the interwebz said you couldn't. I've lost count of the rounds through them. I never had a problem with leading. A couple.of passes with a brush every 4 or 500 rounds kept things in order. I've been shooting PC cast for over a decade now with zero issues. I use the same brass in all my 9mm's and have had a chambering problem with only a couple of rounds in all these years.

Oh wow. Ya I’ll make sure to inspect with specific attention to that but I can’t say that I’ve seen that on any of the brass I’ve shot

It’s very obvious when you do find it, I’ll have to do a quick check in some of my buckets of cleaned 9mm brass I pick up after ipsc matches at my club. The glock firing pin struck is easy to pick out, haven’t noticed any yet but that doesn’t mean there isn’t any bulges.
 
If it was me, since I couldn't replace it if it failed, I would shoot production bullets. Imho.

If it detonates you have nothing, all the saved money in the world won't be worth that.

A reasonable point, except that I know of no circumstances where using a cast lead bullet instead of a jacketed bullet would cause the destruction of a Glock pistol.
