It's simply a public list of people that have applied for and received, renewed, or modified existing handgun permits in the last 5 years. It doesn't mean the permit holders even own a handgun nor does it specify any information whatsoever about their collection of handguns. Further, it absolutely does not mention rifle owners, since those do not require a permit.
However in this thread:
1.) List has likened pistol permit owners to sex offenders
2.) List gives criminal a detailed inventory so they know who to rob
3.) Has compromised undercover police officers and outed them
