1 - Keep in mind that you bought a GLOCK for a reason. The gun is a tank, it will shoot pretty much anything. That includes steel & aluminum cased ammo - no idea why you think you can't shoot steel through your GLOCK.
2 - That said, so long as the reloads come from a reputable source, there's no reason not to shoot them. There are a couple local reloaders and a few national ones that I've been doing business with for years, without a hiccup. Competitive shooters put thousands of rounds of reloaded/remanufactured ammo through their GLOCKs every year without a problem. Just be diligent, do your homework, and inspect your ammo before you load it (that goes for commercial ammo too).
3 - Avoid no-name reloads. Since ammo prices have gone through the roof, every Fudd with a Dillon and a smelting pot has started making his own ammo and hocking it online and at gun shows. And people have also been selling any ammo they can get their hands on, including old ammo loaded by G*d-knows-who from G*d-knows-when pulled out of garages and attics and estate sales. Don't trust the stuff. If you buy reloads, know who you're buying it from, who did the actual reloading, and check their reputation first.
4 - Pretty soon you're going to be shooting your own reloads anyway.
5 - The polygonal rifling in a GLOCK doesn't play well with lead bullets, and it could foul quickly, depending on the hardness of the lead and the round count between cleanings. It's not catastrophic, and if you clean your barrels diligently you can avoid any problems (as others in this thread will attest). However, all things being equal, jacketed, plated or coated bullets are recommended over cast lead.
6 - The ONLY remanufactured ammo I would specifically recommend you avoid is
Ultramax. It's carried by Dicks and several other big box stores. A Google search should give you an idea of their reputation, and I personally have had catastrophic failures using Ultramax ammo.
To the OP... what does the AG have to do with reloads ? Is it illegal ?
Martha gets cranky if companies ship ammo to Massachusetts.
