SUMMARY ORDER

At a stated term of the United States Court of Appeals for the Second Circuit, held at the Thurgood Marshall United States Courthouse, at Foley Square, in the City of New York, on the 16th day of May, Two thousand and six.

UPON DUE CONSIDERATION, it is hereby ORDERED, ADJUDGED, AND DECREED that the judgment of the district court is AFFIRMED.

Defendant-appellant Solomon Billups appeals from a judgment of conviction and sentence entered on August 26, 2005 in the United States District Court for the Northern District of New York (Hurd, J.). Billups pled guilty to possession of a fire*81arm after having pled guilty to a felony in violation of 18 U.S.C. § 922(g)(1) and possession of cocaine base (crack cocaine) with intent to distribute in violation of 21 U.S.C. § 841(a)(1) and (b)(l)(B)(iii). In his plea agreement, Billups reserved the right to challenge on appeal the district court’s denial of his motion to suppress certain physical evidence. We assume the parties’ familiarity with the facts in this case, the relevant procedural history, and the issues on appeal.

I. The District Court’s Denial of Bill-ups’ Motion to Suppress

Billups challenges the district court’s denial of his motion to suppress evidence obtained in the search of his apartment. Billups argues that the search warrant and application did not contain facts sufficient to establish probable cause. We disagree.

‘We review the factual findings on which the district court’s suppression ruling was based ... for clear error, viewing the evidence in the light most favorable to the government; the legal conclusions on which this ruling was based are reviewed de novo.” United States v. Watson, 404 F.3d 163, 166 (2d Cir. 2005) (internal quotations omitted). “[T]he duty of a reviewing court is simply to ensure that the magistrate had a substantial basis for ... concluding] that probable cause existed.” United States v. Smith, 9 F.3d 1007, 1012 (2d Cir. 1993) (internal quotations omitted). The reliability of an informant’s information is evaluated under a totality of the circumstances test. See Illinois v. Gates, 462 U.S. 213, 230, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983). We stated in United States v. Wagner, 989 F.2d 69 (2d Cir. 1993), that “[e]ven where an informant has no proven record, if an informant’s declaration is corroborated in material respects, the entire account may be credited, including parts without corroboration.” Id. at 73.

Here, the warrant application was based on information from confidential informants that was adequately corroborated.1 The first confidential informant (“Cl# 1”) reported that two individuals named Solomon and Teandra were selling crack cocaine at the apartment in question, and that the Cl had seen a “black colored handgun” at the apartment. Based on Cl# l’s information, Detective Gavigan monitored the address and observed what he believed to be crack deals taking place there. Specifically, he saw individuals exiting the apartment with crack cocaine, which they would place in their mouths to avoid detection. Detective Gavigan also met with a second confidential informant (“Cl# 2”), an individual who was known to the police and who provided a statement based on his own personal observations of Billups, his girlfriend, and the apartment in question. Cl# 2 described in detail a handgun he had seen in Billups’ possession at the apartment on at least two occasions. Cl# 2’s statement was based on his own personal observations of this activity, and made it clear that he had been acquainted with Billups for some time and that he had been to the apartment on several occasions.2 Because the detailed statement of Cl# 2 and the observations of Detective Gavigan amply corroborated the informa*82tion provided by Cl# 1, the magistrate had a substantial basis for concluding that probable cause existed.3

II. The District Court’s Decision Not to Hold an Evidentiary Hearing

Billups also argues that the district court’s decision not to hold an evidentiary hearing on the suppression motion was error. This decision is reviewed under an abuse of discretion standard. United States v. Pena, 961 F.2d 333, 339 (2d Cir. 1992). An evidentiary hearing is only required where “contested issues of fact going to the validity of the search are in question.” Watson, 404 F.3d at 167 (internal quotations omitted). In this case, Bill-ups acknowledged that his position was that the warrant application was not sufficient as a matter of law. Because there were no contested issues of fact going to the validity of the search, it was not an abuse of discretion not to hold a hearing.

Nor was a hearing required under Franks v. Delaware, 438 U.S. 154, 155-56, 98 S.Ct. 2674, 57 L.Ed.2d 667 (1978) (requiring a hearing where the defendant “makes a substantial preliminary showing that a false statement knowingly and intentionally, or with reckless disregard for the truth, was included by the affiant in the warrant affidavit and ... the allegedly false statement is necessary to the finding of probable cause.”). Billups argues that a Franks hearing was required because the “tip sheet” attached to the warrant application indicated that Cl# 1 was not “[k]nown to [the] call taker,” when in fact Cl# 1 was known to the police. Even if true, this information would have enhanced, rather than diminished, probable cause, and so any false statement was not necessary to the finding of probable cause.

For the foregoing reasons, the judgment of the district court is AFFIRMED.
