Bernard Allen Charles (“Charles”) was indicted for possession with intent to distribute more than 50 grams of cocaine base (“crack”) in violation of 21 U.S.C. § 841(a)(1), possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1), possession of a firearm in furtherance of a drug trafficking crime, in violation of 18 U.S.C. §§ 924(c)(1)(A) and (c)(l)(B)(ii), and two counts of forfeiture pursuant to 21 U.S.C. § 853 and 18 U.S.C. *404 § 924(d)(1). Subsequently, the government filed a superseding indictment that added additional charges for possession of an unregistered silencer in violation of 26 U.S.C. § 5861(d) and possession of a silencer without a serial number in violation of 26 U.S.C. § 5861®.
Prior to trial, Charles moved to suppress all the physical evidence discovered at the time of his arrest and subsequently seized pursuant to a search warrant. This motion was denied and he was convicted by a jury on all counts. After the trial, Charles filed a written motion for a judgment of acquittal, which the district court also denied. Charles was sentenced to 620 months of imprisonment. On appeal, Charles challenges the denial of both motions. Because we find no erroi*, we affirm his conviction on all counts.
I.
On September 15, 2003, Chief Brannon Decou of the Broussard Police Department received an anonymous tip that Bernard Charles was storing narcotics in a storage facility on Louisiana Highway 182. The tipster also informed Chief Decou that Charles drove a white four-door Dodge pick-up truck. Chief Decou contacted the facility to verify the tip and was given a list of tenants, which indicated that unit F-19 was leased by Paula Charles. Chief Decou then confirmed that Paula and Bernard Charles shared the same address, that Paula Charles was the registered owner of a white Dodge pick-up, and that Bernard Charles was the subject of several outstanding warrants, most for traffic offenses, both in Broussard and in neighboring jurisdictions. With the consent of the storage facility owner, Chief Decou brought a drug dog to sweep the F building and the dog alerted on unit F-19, the unit rented to Paula Charles.
Chief Decou did not attempt to obtain an arrest warrant for Charles. On the morning of September 17, 2003, Chief De-cou, Sergeant Darryl Vernon, and Chief Deputy Timothy Picard began conducting surveillance on the Charles’s storage unit. Just after 8:00 a.m., the officers saw a white four-door Dodge pick-up enter the storage facility. Deputy Picard observed through binoculars as the driver opened the unit, entered it, brought some envelopes back to the truck, and reentered the unit. At this point, the officers decided to arrest Charles.
Picard and Vernon approached the unit with their guns drawn. When they reached the entrance, Charles was standing between the left wall of the storage unit and the driver’s door of a convertible parked inside the unit. When the officers identified themselves, Charles dropped an envelope into the open convertible. Charles was ordered out of the unit onto the ground, where he was arrested and cuffed without incident. As Charles was being read his Miranda rights and escorted to a police cruiser, Picard entered the unit and checked inside, under, and around the convertible to ensure that there were not other occupants in the unit. While inside the unit, Picard noticed that the envelope Charles had dropped into the convertible, now open on the front seat, contained a substance he recognized as crack cocaine. He also saw a partially disassembled firearm on top of a cardboard box in the corner of the storage unit.
Once the preliminary sweep was complete, Picard “froze” the scene and the officers obtained a search warrant based in part upon Picard’s observations while in the unit. Upon executing the warrant, officers seized (1) a partially disassembled SWD model M12 .380 caliber semi-automatic pistol, (2) a homemade silencer threaded to match that weapon, (3) a total *405 quantity of 447.18 grams of crack cocaine, and (4) approximately $3,000 in currency.

Charles contends on appeal that the district court erred in denying his motion to suppress the evidence obtained from the storage unit because, he argues, the initial warrantless entry into the unit was unconstitutional and the results of that entry led the officers to seek a search warrant. In reviewing the denial of a motion to suppress, “the district court’s findings of facts are reviewed for clear error, viewing the evidence in the light most favorable to the government.”
United, States v. Waldrop,
B.
Warrantless searches “are per se unreasonable under the Fourth Amendment — subject only to a few specifically established and well delineated exceptions.”
United States v. Paige,
Charles fails to recognize, however, that under the Supreme Court’s holding in
Maryland v. Buie,
the police may, “as a precautionary matter and
without probable cause or reasonable suspicion,
look in closets or other spaces
immediately adjoining the place of arrest from which an attack could be launched.”

Charles also argues on appeal that the district court erred in denying his motion for acquittal. He maintains that the evidence at trial was insufficient to show that he possessed the firearm found in the storage unit in furtherance of a drug trafficking offense as required by 18 U.S.C. § 924(c)(1)(A). Secondly, he argues — in a one-sentence footnote — that because the silencer was not attached to the firearm when it was found, the jury’s finding that the firearm was “equipped with a silencer” pursuant to 18 U.S.C. § 924(c)(1)(B) was not supported by the evidence. We review each issue in turn. .
The district court’s denial of a motion for judgment of acquittal is reviewed
de novo. United States v. Delgado,
B.
In deciding whether Charles possessed the gun in furtherance of his drug trafficking, we first note that the “mere presence” of a firearm at the scene of drug activity does not alone amount to possession in furtherance of that activity. Rather, the government must present “evidence more specific to the criminal defendant, showing that his or her possession actually furthered the drug trafficking offense.”
United States v. Ceballos-Torres,
The evidence introduced at Charles’s trial showed that the weapon discovered in the storage unit was a .380 caliber semi-automatic “Mack” pistol. M-though disassembled, it could have been made ready for use in short order. The *407 weapon was found in close proximity to over 400 grams of crack cocaine and a large amount of currency. The weapon was also located near an unregistered silencer modified to fit it. Furthermore, as a convicted felon, Charles was not permitted to possess any firearm for any purpose. Considering the evidence presented, the jury reasonably could have found that Charles possessed the weapon in furtherance of a drug trafficking offense.
Charles’s arguments to the contrary are not persuasive. He advocates at length for the application of the Sixth Circuit rule in
United States v. Mackey,
which requires that for a firearm to be possessed in furtherance of a drug crime, it “must be strategically located so that it is quickly and easily available for use.”
Charles also maintains that the circumstances surrounding the discovery of the firearm cannot support his conviction because the firearm was found in a locked storage unit leased to someone other than Charles (i.e. Paula Charles); furthermore no evidence was presented that he ever sold drugs out of the storage unit or that he expected anyone to be present the day the firearm was seized. Charles notes that most of the drugs were found in the convertible, which was not registered to him and that none of his prints were lifted off the gun or silencer. Although Charles is correct that the evidence presented at trial did not rule out any theory of innocence, the evidence is certainly enough that a reasonable trier of fact could have concluded that the elements of the offense were established beyond a reasonable doubt.
See United States v. Resio-Trejo,
C.
With respect to the silencer, Charles contends that because it was not attached to the firearm when it was found, the jury’s finding that the firearm was “equipped with a silencer” pursuant to 18
*408
U.S.C. § 924(c)(l)(B)(ii) is
not
supported by the evidence. Charles raises this argument in a one-sentence footnote and provides no authority for the proposition. Inadequately briefed issues are deemed abandoned.
Dardar v. Lafourche Realty Co.,
IV.
For all of the foregoing reasons, the district court’s denial of the motion to suppress and its denial of the motion for acquittal are
AFFIRMED.
Notes
. The government argued, and the district court found, that Picard’s survey of the storage unit was based on his concern that another individual might be there.
. We note that although "[t]he seizure of obviously incriminating evidence found during a protective sweep is constitutionally permissible pursuant to the plain view doctrine,” the arresting officers in this case took the additional precaution of sealing the scene and obtaining a search warrant before removing any evidence.
