OPINION
This action challenges the constitutionality of Title XI of the Violent Crime Control and Law Enforcement Act of 1994, commonly referred to as the “semi-automatic assault weapons ban.” It was originally brought by the National Rifle Association, a group of gun manufacturers and retail
*386
ers, and a number of individual gun owners. The complaint alleged violations of due process, of equal protection, and of the commerce clause. The district court initially dismissed the action for lack of standing and lack of ripeness.
National Rifle Ass’n v. Magaw,
The plaintiffs now appeal, abandoning the commerce clause challenge but claiming that the Act violates the equal protection component of the Fifth Amendment, on the ground that the statutory definitions are not rationally related to a legitimate governmental interest. The plaintiffs also present, for the first tíme on appeal, a First Amendment argument that was not fully developed below. We find no reversible error and affirm.
LEGISLATIVE BACKGROUND
Gun regulation in America has existed throughout the nation’s history.
2
In recent times, congressional regulation of interstate commerce in firearms has commonly taken the form of licensing and registration requirements as part of the National Firearms Act of 1934. However, when the National Firearms Act proved ineffective in controlling semi-automatic gun-trafficking, the result was passage in 1968 of the Omnibus Crime Control and Safe Streets Act. The stated purpose of the 1968 legislation was to “strengthen federal controls over interstate and foreign commerce in firearms and to assist the States effectively to regulate firearms traffic within their borders.” H.R.Rep. No. 90-1577 (1968), reprinted in 1968 U.S.C.C.A.N. 4410, 4411. In 1989, the Bureau of Alcohol, Tobacco and Firearms banned the importation of assault weapons after finding that they did not meet the “sporting purposes” test of the Gun Control Act of 1968.
See Gun South, Inc. v. Brady,
*387 As a result of the- growing attention to the threat posed by American-made semiautomatic weapons, several bans were proposed both in the House and Senate, all facing fierce opposition by gun rights lobbying groups. In an effort to compromise between the growing concern surrounding semi-automatic weapons and the demands of the gun rights groups, Senator Diane Feinstein proposed a list of common hunting and sporting rifles that would not be subject to the assault-weapon ban. The list, aimed at ensuring that the ban was not used to target recreational firearms, enumerated over 670 weapons. After overcoming several political hurdles, the semi-automatic assault weapons ban was included in the Violent Crime Control and Law Enforcement Act signed into law on September 13,1994, by President Clinton. 4
Section 110102(a) of the 1994 Act makes it “unlawful for a person to manufacture, transfer, or possess a semiautomatic assault weapon.” 18 U.S.C. § 922(v)(l). Section 110102(b) defines “semiautomatic assault weapon” with a list of weapons enumerated by name, also outlawing any “copies or duplicates of the firearms” listed. See 18 U.S.C. § 921(a)(30)(A). In addition to the enumerated weapons and copies or duplicates thereof, section 110102(b) also classifies semi-automatic rifles and semi-automatic pistols that have the ability to accept a detachable magazine and two of five enumerated accessories, as well as semi-automatic shotguns that have any two of four enumerated features, as “semiautomatic assault weapons” forbidden by the statute. 5 See U.S.C. §§ 921(a)(30)(B)-(D).
In enacting the law, Congress provided several protective measures for gun owners. First, Section 110102(a) of the 1994 Act contains a grandfather clause that exempts semi-automatic weapons lawfully possessed at the date of enactment from its provisions. See 18 U.S.C. § 922(v)(2). Additionally, the statute does not apply to a list of enumerated firearms, as well as replicas or duplicates of those firearms. See id. § 922(v)(3); id. App. A.
ANALYSIS
The plaintiffs allege that this legislative scheme is unconstitutional both because it irrationally classifies weapons in violation of equal protection and because it violates the First Amendment by regulating “emotive speech.”
The latter question need not long detain us long. The First Amendment claim was not included in the complaint or in the amended complaint filed in this action. Indeed, the plaintiffs’ only mention of a free speech argument was made in passing in their brief in opposition to the defendants’ motion for summary judgment. For this reason, the district court declined to rule on the issue, characterizing it as “underdeveloped.” As a general rule, we would likewise decline to review the issue, there being no decision to sustain or reject on appeal.
See, e.g., Taft Broadcasting Co. v. United States,
There remains the equal protection question, which is raised here under the Fifth Amendment’s Due Process Clause. The district court held that the claim was non-cognizable because the Equal Protection Clause protects against inappropriate classifications of people, rather than things. This position has been adopted by several courts.
See, e.g., Benjamin v. Bailey,
We conclude, however, that by honoring the basic canon of avoiding constitutional questions where possible, we need not decide the scope of equal protection in order resolve the issue presented in this case.
See, e.g., United States v. Security Industrial Bank,
If legislation neither burdens a fundamental constitutional right nor targets a suspect classification, it will withstand constitutional scrutiny so long as it bears a rational relationship to a legitimate government interest.
Romer v. Evans,
Although parties challenging legislation under the Equal Protection Clause may introduce evidence supporting their claim that it is irrational, United States v. Carolene Products Co.,304 U.S. 144 , 153-54,58 S.Ct. 778 ,82 L.Ed. 1234 (1938), they cannot prevail so long as “it is evident from all the considerations presented to [the legislature], and those of which we may take judicial notice, that the question is at least debatable.” Id., at 154,58 S.Ct. 778 . Where there was evidence before the legislature reasonably supporting the classification, litigants may not procure invalidation of the legislation merely by tendering evidence in court that the legislature was mistaken.
Clover Leaf Creamery,
The allegations of irrationality made by the plaintiffs in this case are twofold: (1) that several of the weapons on the prohibited list are the functional equivalents of weapons specifically protected under the 1994 Act, and (2) that the statutory criteria outlawing other unlisted semi-automatic weapons serve no legitimate government purpose.
The plaintiffs do not seriously dispute the legitimacy of congressional legislation generally regulating assault weapons, nor do they argue that the weapons protected under the statute could not have been outlawed by Congress. Rather, they argue that variations in the specificity of weapon descriptions and lack of common characteristics in the list of weapons outlawed destroy the constitutional legitimacy of the 1994 Act. This argument is without merit. The list of outlawed weapons was developed by recognizing weapons commonly used in the commission of violent crimes. The “copies or duplicates” language was added to the legislation in order to prevent manufacturers from dodging criminal liability by simply changing the name of the specified weapons.

The list of protected weapons was developed based on information provided to congressional representatives that those weapons were commonly used for hunting purposes. Accordingly, it is entirely rational for Congress, in an effort to protect public safety, to choose to ban those weapons commonly used for criminal purposes and to exempt those weapons commonly used for recreational purposes. The fact that many of the protected weapons are somewhat similar in function to those that are banned does not destroy the rationality of the congressional choice. A classification does
*390
not fail because it “ ‘is not made with mathematical nicety or because in practice it results in some inequality.’”
Dandridge v. Williams,
The plaintiffs also argue that the ban on semi-automatic weapons with more than one of the enumerated features is irrational because the 1994 Act allows a weapon with one of the features, and the individual features do not work in tandem with each other. This argument is also without merit. Each of the individual enumerated features makes a weapon potentially more dangerous. Additionally, the features are not commonly used on weapons designed solely for hunting. Congress could easily have determined that the greater the number of dangerous add-ons on a semi-automatic weapon, the greater the likelihood that the weapon may be used for dangerous purposes. Further, Congress may work incrementally in protecting public safety.
See, e.g., Semler v. Dental Examiners,
CONCLUSION
For the reasons set out above, we conclude that the semi-automatic assault weapons ban, while perhaps not flawless in its execution, is a legitimate exercise of congressional authority to regulate a significant threat to public health and safety. Because the plaintiffs have failed to demonstrate that the ban violates equal protection, we AFFIRM the judgment of the district court granting summary judgment to the defendants.

See 1994 U.S.C.C.A.N. 1801, 1820, 1821 & n. 3 (listing House hearings); Assault Weapons: A View From the Front Lines: Hearing on S. 639 and S. 653 Before the Senate Committee on the Judiciary, 103d Cong. (1993). During the hearings, testimony outlining the dangers of semi-automatic weapons was received from a variety of sources: gun experts, law enforcement officials, community activists, medical groups, emergency room doctors, and politicians.

. The enumerated features outlined in the legislation include:
(i) a folding or telescoping stock;
(ii) a pistol grip that protrudes conspicuously beneath the action of the weapon;
(iii) a bayonet mount;
(iv) a flash suppressor or threaded barrel design to accommodate a flash suppresser; and
(v) a grenade launcher.

. Many scholars believe that the challenge in Clover Leaf was cognizable because distinguishing between the two types of milk cartons was effectively distinguishing between instate and out-of-state milk producers. Even though the Court did not find that the provision amounted to economic protectionism, regulation of the right to engage in a livelihood based on slate citizenship clearly raises a more traditional question of equal protection than does the regulation now before us. See, e.g., Robert C. Ferrell, Legislative Purpose and Equal Protection’s Rationality Review, 37 Vill. L.Rev. 1 (1992).
. The plaintiffs argue that a Bureau of Alcohol, Tobacco and Firearms decision to not classify a specific semi-automatic weapon in an individual criminal case in Michigan as a “copy or duplicate” under the meaning of the statute constitutes an official agency determination that the "copy or duplicate” language is “surplusage”. See State v. Conyers, E.D. Mich. # 97-80471 (unpublished disposition). An agency’s decision not to enforce a provision of a criminal statute in an individual case does not constitute a binding agency determination that the statute lacks rationality or enforceability.
