HK if you can afford it. Sig 229 is right up next to it. For less money and still a great package, M&P. XD is fine, and the Glock series is okay if you're not going to have really high round counts. Of the Glocks, I'd go with the G23 or G35.
As to weapons jamming, there's no such thing as one that never ever will: unless of course you plan to never feed it or function it. It's never a question of jamming, it's a question of whether or not you can overcome the jam quickly and consistently. No gun is human fool proof. People have incredible ability to screw things up. Which brings me to my next point:
If you are complaining about accidental discharges, you need to rethink the terms you are using. Discharges are rarely "accidental". They are nearly always "negligent". If you don't have the sense to unload and then re-check a weapon before disassembly, then you should not have ANY gun, not even a revolver or single-shot breech loader. Handling a weapon requires a serious approach, not a flippant, casual, or careless one.
If you aren't comfortable with a weapon's features, then fine, buy something else. Everybody has an opinion or set of "feelings" about stuff, otherwise all guns would be the same (and who knows how that would be). But let one thing be clear: DESIGN, FUNCTION, AND FEATURES WILL NEVER TAKE THE PLACE OF SERIOUS SAFETY AND TRAINING.
So quit blaming the dang guns. It's usually the idiot holding them. Lest I seem hypocritical, this is coming from someone has taken the idiot path before in the distant past and will never do so again....
