I'm an NRA certified instructor, NRA range safety officer, and IDPA safety officer.
The Glock 19 is a good choice, even for a beginner. The XD is fine, but is in no way safer than a Glock. And I certainly do not recommend a DA/SA semi-auto like a Beretta.
.357 SIG? No thanks, and absolutely not a good choice for a beginner. First, .357 SIG is stupidly expensive and often hard to find. Second, it has a very large flash and loud report -- beginners already have a hard enough time not flinching and .357 SIG is just going to exacerbate that. For reloaders, .357 SIG just sucks compared to a straight-walled pistol cartridge like 9mm or 45 ACP.

This is exactly why I went with the XD. I have both a .45 and .40. They're great guns. I'll repeat what everyone else said. Find what fits YOU best and practice, practice, practice!
Glock 19
SW M&P 9
SIG 239
in that order....
I would roll the dice on a glock jamming and have 15 +1 over a 5 round revolver any day. Besides with the proper training and practice clearing a "jam" is easy and can be done faster that a revolver reload.
My best friend was involved in a shooting years ago, and was carrying a Sig P226 at the time. Several 9mm rounds didn't stop the guy in a timely manner. After that he started carrying a .45 ACP. That also weighed heavily in my decision to go with the .45 ACP.
Having 13+1 rounds of 230g JHP Golden Saber, is reassuring. I only pray that I never need it for more than putting holes in paper targets.
I'll go with recommendations of people like John Farnam, the USSS, Texas DPS and many, many more.
