Specifically for reloads, the hammer-fired Ruger P series (P85, P89, P94, P95) are all top choices. CDNN currently has P95's for around $250. Highly recommended.
However, any safe handgun should shoot reloads that are properly loaded. Due to the polygonal rifling, Glocks may have an issue with lead bullets. You can swap the barrel or not use lead bullets, or not use a Glock. Incidentally, from what I read HK's always have an issue with lead bullets while Glocks only sometimes do, even though both use roughly the same barrel design. Is there really a difference or just mixed ideas of what constitutes a problem? I don't know.
Also, I had read about the difficulty of reloading 9mm and had been intimidated by it, but I have had zero problems reloading it myself, as only the second type of cartridge I've tried reloading (after straight-as-straight-walled gets .38 and .357 mag). While the 9mm case is slightly tapered, it reloads just like a 38 as long as you don't over-flare the case mouth. And I was using pretty much max flare to get easy bullet seating. The biggest issue with reloading 9mm is that if you use a single stage press, the small cases are a bit clumsy to insert and remove, just because of their small size.
