Nice thing about the Glock in 10mm is you can run the hottest loads through it. Get a Lone Wolf conversion barrel and shoot hard cast lead. I would shoot much stouter loads in a Glock than any 1911 based 10mm. Of course when comparing a Glock to my Delta Elite, the Glock is kind of a disposable gun. If I batter a Glock to death I probably wouldn't feel real bad about it.

If you clean on a regular basis, cast bullets, hard or soft isn't really a problem. You'd have to do several hundred hot soft-cast loads without cleaning for it to build up in the flats of the polygonal rifling. The whole thing is just a CYA move by Glock to avoid a lawsuit from someone who's really cheap and shoots lots of soft-cast, and is really lazy, never cleaning. HK and others with polygonal rifling have never even bothered to print any warnings on the issue that I'm aware of.
And now there's the new idea to do polymer powdwercoating to cast bullets reducing leading to almost zero.
Although if you're shooting hot loads, you might want to go with an aftermarket Lone Wolf barrel anyway because of the little unsupported gap where the feed ramp cuts into the web a bit that Glock has for the sake of feed reliability at the expense of full chamber/case support. Although even then, Glock has been quietly reducing the exposed web at the feed ramp over the generations and the gap is much smaller than it was in years past.
