1. A perforating gun system comprising: at least one charge disposed within a gun body; anda first sleeve disposed within the gun body about the at least one charge, wherein the first sleeve comprises a first expansion section, wherein the entire first sleeve is configured to undergo non-uniform radial expansion in response to the detonation of the at least one charge, and wherein the first sleeve is configured to at least partially circumferentially misalign an aperture in the first sleeve with a hole in the gun body after the radial expansion of the first sleeve. 2. The system of claim 1, wherein the first sleeve comprises the aperture, wherein the aperture is aligned with an explosive focal axis of the at least one charge within the gun body. 3. The system of claim 1, the system further comprising at least one charge holder configured to retain the at least one charge within the gun body. 4. The system of claim 1, wherein the first sleeve is configured to at least partially obstruct a passage between an interior of the gun body and an exterior of the gun body in response to the detonation of the at least one charge. 5. The system of claim 1, wherein the first expansion section comprises a slit longitudinally disposed along the first sleeve. 6. The system of claim 1, wherein the first expansion section comprises overlapping ends of the first sleeve. 7. The system of claim 1, wherein the first expansion section comprises a breakable section longitudinally disposed along the first sleeve. 8. The system of claim 1, the system further comprising a second sleeve disposed within the gun body about the at least one charge. 9. The system of claim 8, wherein the second sleeve comprises a second expansion section, and wherein the second sleeve is configured to radially expand in response to the detonation of the at least one charge. 10. The system of claim 1, wherein the second sleeve is disposed concentrically with the first sleeve. 11. The system of claim 1, wherein the second sleeve is configured to at least partially obstruct a passage between an interior of the gun body and an exterior of the gun body in response to detonating the charge. 12. A perforating gun system comprising: at least one charge disposed within a gun body;a first sleeve disposed within the gun body about the at least one charge, wherein the first sleeve comprises a first expansion section, and wherein the first sleeve is configured to undergo non-uniform expansion in response to the detonation of the at least one charge;a second sleeve disposed within the gun body about the at least one charge, wherein the second sleeve comprises a second expansion section, wherein the second sleeve is configured to radially expand in response to the detonation of the at least one charge, and wherein the first expansion section and the second expansion section are radially offset. 13. The system of claim 12, wherein the first expansion section and the second expansion section are radially offset between about 5 degrees and about 180 degrees. 14. A method of preparing a perforating gun system for use in a perforating operation, the method comprising: providing at least one charge disposed within a gun body; anddisposing a first sleeve comprising a first expansion section within the gun body about the at least one charge, wherein the first sleeve comprises an aperture, wherein the aperture is aligned with an explosive focal axis of the at least one charge, wherein the first sleeve is configured to radially expand into contact with an inner surface of the gun body in response to a detonation of the at least one charge and at least partially circumferentially misalign the aperture with a hole in the gun body after the detonation of the at least one charge. 15. The method of claim 14, further comprising disposing a second sleeve comprising a second expansion section within the gun body about the at least one charge, wherein the second sleeve is configured to radially expand in response to the detonation of the at least one charge. 16. The method of claim 14, further comprising providing an aperture in the first sleeve, wherein the aperture is radially aligned with the at least one charge. 17. A method of perforating a wellbore, the method comprising: detonating at least one charge in a gun body;forming a hole in the gun body in response to the detonating, wherein a first sleeve disposed within the gun body comprises an aperture, and wherein the hole in the gun body and the aperture in the first sleeve align along an explosive axis of the at least one charge;increasing the radius of a first sleeve disposed within the gun body in response to the detonating; andat least partially misaligning the aperture in the first sleeve with the hole in the gun body in response to increasing the radius of the first sleeve. 18. The method of claim 17, further comprising; increasing the radius of a second sleeve disposed within the gun body in response to the detonating, wherein the second sleeve comprises a second aperture; andat least partially misaligning the second aperture with the aperture. 19. The method of claim 17, further comprising retaining debris within the perforating gun system in response to the at least partially misaligning. 20. The method of claim 17, wherein the at least partially misaligning comprises circumferentially misaligning, longitudinally misaligning, or any combination thereof.
