==============================================
You might want to consider putting questions concerning HR 218 to bed with the following.  I am quoting the law directly, as it pertains to retirees.
 
" the Law Enforcement Officers Safety Act of 2004.  Section 3. EXEMPTION OF QUALIFIED LAW ENFORCEMENT OFFICERS FROM STATE LAWS PROHIBITING THE CARRYING OF CONCEALED FIREARMS.
(a) In general  -  Chapter 44 of title 18, United States Code, is further amended by inserting after section 926B the following:
Sec. 926C.  The carrying of concealed firearms by qualified retired law enforcement officers
 
(a) Notwithstanding any other provision of the law of any state or any political subdivision thereof, any individual who is a qualified law enforcement officer and who is carrying the identification required by subdivision (d) may carry a concealed firearm that has been shipped or transported in interstate or foreign commerce, subject to subsection (b).
(b)  This section shall not be construed to supercede or limit the laws of any state that--
 
(1) permit private persons or entities to prohibit or restrict the possession of concealed firearm on their property; or
(2) prohibit or restrict the possession of firearms on any state or local government property, installation, building, base, or park.
 
(c) As used in this section, the term "qualified retired law enforcement officer means an individual who--
 
(1) retired in good standing from service with a public agency as a law enforcement officer, other than for reasons of mental instability;
(2) before such retirement, was authorized by law to engage in or supervise the prevention, detection, investigation, or prosecution of, or the incarceration of any person for, any violation of law, and had  statutory powers of arrest;
(3)(A) before such retirement, was regularly employed as a law enforcement officer for an aggregate of 15 years, or more; or
(B) retired from service with such agency, after completing any applicable probationary period of such service, due to a service connected disability, as determined by such agency;
 
(4) has a nonforfeitable right to benefits under the retirement plan of the agency;
(5) during the most recent 12 month period, has met, at the expense of the individual, the State's standards for training and qualification for active law enforcement officers to carry firearms;
(6) is not under the influence of alcohol or another intoxicating or hallucinatory drug or substance; and
(7) is not prohibited by Federal law from receiving firearms.
 
(d) The identification required by this subsection is--
 
(1) a photographic identification issued by the agency from which the individual retired from service as a law enforcement officer that indicates that the individual has, not less than one year before the date the individual is carrying the concealed firearm, been tested or otherwise found by the agency to meet the standards established by the agency for training and qualification for active law enforcement officers to carry a firearm of the same type as the concealed firearm; or
(2)(A) a photographic identification issued by the agency from which the individual retired from service as a law enforcement officer; and
(B) a certification issued by the State in which the individual resides that indicates that the individual has, not less recently than one year before the date the individual is carrying the concealed firearm, been tested or otherwise found by the State to meet the standards established by the State for training and qualification for active law enforcement officers to carry a firearm of the same type as the concealed firearm."
 
Note that Section 1 above refers to those retirees who will receive the required qualification course from the agency from which they retired, and Section 2 refers to members who have moved to another state, and such state offers the required qualification course.
 
The law also goes on to state that the term firearm does not include silencers or machine guns.  I have marked. in bold, and in some cases underline, those sections which are of specific interest to retired members. The law, as quoted, is relatively self explanatory, and should be well understood by anyone familiar with reading law. Further, it answers most all of the questions or inquiries that I have seen posted by you.
