The federal laws do not apply to many abusers who victimize non-spouse partners. Domestic violence affects people in family or intimate relationships that fall outside the protections of federal law. For example, dating partners are not within the federal prohibitions unless the partners have cohabitated as spouses or have a child in common. The risk of domestic violence being committed by a dating partner is well documented.

The federal laws do not apply to abusers who victimize a family member other than a partner or child. The current federal prohibitions also do not address violence against family members other than a child or intimate partner. They therefore do not address violence against someone like an abused sibling or parent.

The federal laws do not apply to convicted stalkers and others subject to a protective order. Similar loopholes in federal law allow access to guns by convicted stalkers13 and abusers subject to domestic violence protective orders that cover the period before a hearing

The federal laws fail to require domestic abusers to surrender their firearms. Federal law does not require domestic abusers to turn in their firearms once they are convicted of a crime of domestic violence or become subject to a restraining order. As a result, abusers continue to commit crimes with guns they are prohibited from owning under federal law.

The federal laws are weakened because not all states report all prohibited abusers. In order for background checks to prevent abusers from obtaining guns, states must report abusers who fall within prohibited categories to the proper databases. Identifying the abusers to be reported involves a series of complex legal issues that many states have not yet addressed.16 As a result, many states do not comprehensively enter domestic violence protective order and offender information into the proper databases.

The federal laws are weakened by ineffectual federal background check laws. Federal law does not require a background check to be performed before every sale of a gun, including sales by unlicensed, private sellers. The private sale loophole enables many domestic abusers to illegally obtain the firearms they use against their victims. In states that require a background check for every handgun sale, 38% fewer women are shot to death by intimate partners

I don't argue with the veracity of your "sources" and seem to find significant holes in your interpretation of the current laws and their subsequent enforcement. It is clear that there are problems, and those problems need to be addressed and corrected, but to widely admonish the law as a complete failure because of your perceived lack of enforcement is suspect to your particular viewpoint.

Again, this is an open discussion on the problem that gun violence has on our society, not the admonishment of any point of view. I again encourage a discussion, but you seem only to want to be confrontational and combative.
