Sherman Ray Meirovitz was convicted of conspiracy to distribute cocaine and possession of cocaine with the intent to distribute and was sentenced to life imprisonment without parole. Meirovitz appeals his conviction, claiming (1) that his Miranda waiver, confession and consent to search his home were involuntary; (2) that the district court 1 erred in admitting weapons and ammunition seized from his home; and (3) that the government failed to prove predisposition to possess cocaine with the intent to distribute. Meirovitz also claims that his sentence is constitutionally disproportionate to his convictions and therefore violates the eighth amendment guarantee against cruel and unusual punishment. We affirm both Meirovitz’ convictions and his sentence.
I.
Meirovitz was arrested on November 30, 1988, after he tried to purchase two kilograms of cocaine from undercover agents. His arrest was the result of an investiga *1378 tion into narcotics trafficking involving persons in Colorado, New York and Minnesota. In April 1988 the agents followed Mu-nir Ahmed, the central figure in a narcotics trafficking organization, to the Embassy Suites Hotel in Bloomington, Minnesota. They saw Jack Sears and another suspect board Ahmed’s flight from Denver to Minnesota; all three men stayed at the Embassy Suites Hotel. The agents did not see these men participating in drug activity on this occasion.
After continued surveillance of Sears in Denver, the police seized Sears’ car, believing it had been used for a drug transaction. Sears agreed to cooperate in the investigation. Sears told the investigators that he was introduced to Meirovitz in December 1986, and that five months afterwards, Meirovitz asked Sears if he could put together a deal for one pound of cocaine. Sears sold the cocaine to Meirovitz for approximately $17,000. Sears also told the investigators that he sold Meirovitz one to four pounds of cocaine approximately every two months.
Sears agreed to call Meirovitz and attempt to set up a deal. Sears told Meiro-vitz that he had a new source who could provide cocaine for $18,500 per kilogram. Meirovitz said he was interested in two kilograms and that he would like to make partial payment in methamphetamine. Sears agreed and the deal was set up for the end of November 1988.
After Sears and the investigators arrived in Minnesota and wired the hotel room to record the conversations, Sears called Meir-ovitz to complete the transaction. Meiro-vitz arrived with $35,700 in cash, one ounce of methamphetamine (worth $1,300), a scale, calculators, plastic baggies, a mirror, and chemicals to test the quality of the cocaine. Meirovitz was given the two kilograms of cocaine and one of the undercover agents began counting the money. Meiro-vitz began explaining in detail the source of the methamphetamine and said that he expected a larger quantity later. As Meiro-vitz tested the cocaine’s quality, the other agents entered the room and arrested him.
Meirovitz was advised of his rights and agreed to be interviewed by the agents. Meirovitz confirmed Sears’ account of their initial meeting and subsequent drug deals. He also told the agents of a lab in California that was being set up to produce twenty pounds of methamphetamine. Meirovitz then consented to a search of his home and car. The search of his home produced $9,500 in $100 bills, seven handguns in a laundry chute, a small-caliber handgun and ammunition, papers characterized by the government as “drug notes,” drug-cutting agents (lactose, mannitol and nicotinamide), an electronic digital scale, drug-related books, numerous plastic baggies, and a hollow battery that contained twelve grams of methamphetamine.
At trial, Meirovitz testified that he had not been involved in the use or distribution of drugs since his release from prison in December 1984. Meirovitz said that Sears asked him to distribute drugs, but that he refused. Meirovitz claimed that Sears kept on pressuring him, threatening violence and exposure of Meirovitz’ involvement with a prostitute. Meirovitz maintained that he agreed to go along with Sears’ deal out of fear. Meirovitz claimed that Sears told him to bring the methamphetamine and to act like he knew what he was doing.
Meirovitz testified that he did not recall receiving any Miranda warnings. Furthermore, he claimed that the agents’ emphasis on cooperation led him to say what he thought they wanted to hear. He also testified that he signed the Miranda waiver forms and consent to search forms without being given an opportunity to read them.
Meirovitz also testified that the drug paraphernalia and drug-related items in his house were either vestiges of his drug-dealing past or property of other persons. Meirovitz presented witnesses who testified that they knew Sears coerced Meirovitz to get involved in drugs.
After a three-day jury trial, Meirovitz was convicted on both counts of conspiracy to distribute and possession with the intent to distribute. The United States Probation Officer calculated his offense level at thirty-eight and his criminal history category *1379 at VI due to his status of career offender. Therefore, Meirovitz’ appropriate sentencing range was thirty years to life. Judge Devitt sentenced Meirovitz to the maximum sentence because of his substantial criminal record which included a history of drug-dealing and the shooting death of his mother-in-law.

A.
We review the district court’s decision to deny the defendant’s motion to suppress under a clearly erroneous standard.
United States v. Williams,
Meirovitz first argues that his waiver of his Miranda rights and his consent to search were involuntarily obtained. The arresting officers testified that Meirovitz was given a Miranda warning and that he signed a Miranda waiver form and consent to search forms. Meirovitz testified that he did not recall having his rights read to him and that he felt pressured to sign the Miranda waiver form and the consent to search forms. The officers’ testimony and the signed forms are substantial evidence that support the district court’s denial of the motion to suppress. Since there was no erroneous interpretation of the applicable law and since the totality of the record leaves us with no firm and definite conviction of mistake, we affirm the district court’s denial of the motion to suppress Meirovitz’ Miranda waiver and consent to search.
Meirovitz also argues that his post-arrest confession was involuntarily obtained. The appropriate test for determining the voluntariness of a confession is “whether, in light of the totality of the circumstances, pressures exerted upon the suspect have overborne his will.”

Meirovitz next claims' that the guns and ammunition found in his home should not have been admitted into evidence because their prejudicial effect substantially outweighed their probative value. Firearms are generally considered tools of the drug dealer’s trade and can be admitted as evidence of intent to distribute.
See
*1380
United States v. Brett,
C.
Meirovitz also claims that the government did not present sufficient evidence to prove beyond a reasonable doubt that he was predisposed to possess cocaine and that therefore, the jury’s conclusion that he was not entrapped is invalid. This court must affirm convictions that are challenged on sufficiency of evidence grounds if, viewing the evidence in the light most favorable to the government, there is substantial evidence to support the jury’s verdict.
Glasser v. United States,
D.
Meirovitz also challenges his sentence of life imprisonment without parole as disproportionate to the offenses for which he was convicted and therefore a violation of the eighth amendment. In general, a sentence is not subject to appellate review unless it “exceeds statutory limits, violates constitutional or procedural requirements, or reflects that the district court failed to exercise its discretion or manifestly or grossly abused its discretion.”
United States v. Marin-Cifuentes,
Solem v. Helm,
Solem
first directs the reviewing court to consider the gravity of the offense and the harshness of the penalty.
Solem,
Except in rare cases, the murderer’s red hand falls on one victim only, however grim the blow; but the foul hand of the drug dealer blights life after life and, like the vampire of fable, creates others in its owner’s evil image — others who create others still, across our land and down our generations, sparing not even the unborn.
Terrebonne v. Butler,
The next step in the
Solem
proportionality analysis is a comparison of Meirovitz’ sentence with sentences imposed on other criminals in the same jurisdiction. There are two aspects to this portion of the analysis: first, whether more serious crimes receive the same penalty; and second, whether similarly-situated criminals receive similar sentences. Determining whether more serious crimes receive the same penalty requires a closer look at the structure of the Sentencing Guidelines. Even though the Guidelines were designed to reduce indeterminacy in sentencing and remove inter- and intra-circuit disparities, the Guidelines have been accused of aggravating the problem they were created to solve.
See Mistretta v. United States,
Meirovitz’ sentence is not disproportionate when compared to other defendants similarly situated in the Eighth Circuit. In
United States v. McKines,
Finally, Meirovitz’ sentence is not disproportionate when compared to sentences imposed for the same crime in other jurisdictions. In
United States v. Martorano,
Considering the three factors enumerated in Solem leads us to conclude that Meir-ovitz’ life sentence without parole, although harsh, does not violate the proportionality requirement of the eighth amend *1383 ment. The additional issues raised by Meirovitz in his pro se brief are either without merit or not properly before this court because they should be raised in a subsequent habeas petition.
III.
For the foregoing reasons, Sherman Ray Meirovitz’ convictions and sentence are affirmed.
