Introduction. Today’s urge to improve the effectiveness of crime investigation increasingly requires attracting resources such as forms of expert research like ‘complex examination’ . In the theory of criminology and forensic formed certain scientific ideas into the nature of complex expertise , its characteristic features.

Introduction. Problematic issues of providing the criminalistic requirements of the Ministry of Internal Affairs of Russia imposed to firearms are considered in work. A sometimes weapons does not provide formation on the shot bullets and cartridge cases of the traces suitable for identification. Absence of any standards or specifications on a roughness of a relief of surfaces of the details forming traces is to it the reason.

Introduction. The legislation of the Russian Federation does not provide for the test shooting of smooth-bore weapons by law enforcement agencies. There are no catridge-cases repository of smoothbore weapons because of low criminalistic information, which, in turn, makes it difficult to investigate crimes committed using this type of firearm. The report considers the possibility of introducing catridge-cases repository of registered smooth-bore weapons. Conceptual possibilities for implementing this solution are described. Theoretical analysis.

Introduction. In the article the possibility of introduction to legal turnover of short-barreled civil firearms is considered. Prerequisites and the imminent problems of society are described, the possibility of introduction of short-barreled civil weapon for his use by citizens for self-defense is considered, at the controlled and directed nature of process of legalization from law enforcement agencies and according to the tactical and technical and criminalistic requirements to this type of weapon agreed by them. Theoretical analysis.

Introduction. Firearms and ammunition are traditionally complex objects for fingerprint identification research. Theoretical analysis. The possibilities of modern laboratory methods for detecting handprints on firearms and ammunition are discussed. It is noted that the most effective method is the vacuum deposition of thin metal films, as well as cyanoacrylic acid esters in vacuum.

Introduction. This article deals with some issues of forensic investigation of civilian firearms manufactured based on combat samples: features of trace formation on bullets and cartridge case design changes of the original models (samples) of the firearms. The authors highlight the problem of the lack of a literary base and illustrative material, necessary for carrying out diagnostic research of traces on bullets and cartridge cases formed when fired from civilian firearms manufactured on the basis of samples of military weapons.

Introduction. The growing number of military and civilian models of firearms equipped with muzzle devices actualizes the expert diagnostics of the facts of using silent shooting devices during committing crimes by their traces on the fi red bullets and fi red cases. Theoretical analysis. Science has identifi ed a number of regularities of the eff ect of silent shooting devices on the mechanism of formation and characteristics of traces on bullets and cartridge cases.

The paper considers the possibility of using laser marking to identify the bore arms on the traces on fired bullets. The analysis of modes of laser processing of a trunk at which traces on the shot bullet can be recognized by suitable to identification, is executed on the basis of the spent experiments.

In the article shown that the actual task is to develop a forensic requirements and criteria which should satisfy the basic parts of firearms. Was shown that the condition of these parts should be such that they ensure the production of shot and normal interaction with other details of a particular model.

In article recommendations available in literature about definition of number of shots from firearms are analyzed. On the basis of the experiments carried out by the author the contentious clauses demanding additional check are allocated. The research directions, allowing to receive more reliable recommendations are offered.
