Can a.22LR fit in a.32 revolver?
The Short Answer: Yes, but…
Before diving into the details, let’s address the obvious: **a.22 Long Rifle (LR) cartridge is slightly smaller than a.32 caliber revolver’s cylinder bore**. But, yes, it is possible to insert a.22LR into a.32 revolver. However, doing so comes with several limitations, and we’ll explore these in this article.
**Theoretical Fitment**
From a purely theoretical standpoint, a.22LR can fit in a.32 revolver due to the following reasons:
• **Caliber mismatch**:.22LR is slightly smaller in diameter (4.53mm vs. 4.8mm) than a.32 caliber, allowing for some degree of compatibility.
• **Cartridge shape**: The.22LR’s taper is similar to the.32 caliber, enabling a partial fit.
• **Yawning tolerances**: Most revolvers have tolerances that allow for slight deviations in cylinder bore diameters, which might accommodate a.22LR.
The Challenges**
Despite the theoretical compatibility, there are several significant issues to consider when trying to fit a.22LR into a.32 revolver:
• **Saftey**: A.22LR chambered in a.32 revolver may lead to catastrophic failures, including:
+ Unintended primer ignition due to the.32 revolver’s firing pin design
+ Deformation or breakage of the.22LR case due to excessive pressure and stretching
+ Unreliable feeding or ejection, causing misfires or stuck cartridges
• **Ammunition deformation**: The.22LR’s thinner walls may flex or deform when chambered in a.32 revolver, compromising its structural integrity
• **Cylinder clearance**: The.32 revolver’s cylinder may not be designed to accommodate the slightly shorter.22LR case, potentially causing chamber binding or ejection issues
**The Practical Reality**
While it is theoretically possible to insert a.22LR into a.32 revolver, the risks involved far outweigh any potential benefits. In practice, **a.22LR should not be used in a.32 revolver**, as the potential consequences can be disastrous.
**A Note on Rebuilding and Modifications**
Some enthusiasts might attempt to modify the revolver’s cylinder or chamber to accommodate.22LR cartridges. However, this approach comes with significant risks, including:
• **Chamber redesign**: Altering the chamber can compromise its integrity and affect the revolver’s accuracy
• **Rebarrel or recylindrering**: Complete overhaul of the revolver can be expensive and may void its warranty
• **Increased complexity**: Modifications may add unnecessary complexity, reducing the revolver’s reliability and durability
**Table: Key Comparisons**
| **Feature** | **.22 Long Rifle (LR)** | **.32 Revolver** |
| — | — | — |
| Caliber (mm) | 4.53 | 4.8 |
| Cartridge shape | Tapered | Tapered |
| Case length (mm) | 15.54 | 17.17 (approx.) |
| Bullet diameter (mm) | 4.5 | 4.85 |
| Chamber pressure (psi) | 20,000-24,000 | 17,000-20,000 (approx.) |
The Verdict**
In conclusion, while it is theoretically possible to insert a.22LR into a.32 revolver, the practical reality is that **it is not recommended or safe to do so**. The risks associated with this combination far outweigh any potential benefits, and modifying the revolver to accommodate.22LR cartridges is not a viable solution.
If you’re considering using.22LR cartridges, ensure you use a revolver specifically designed for this caliber or explore alternative options, such as dedicated.22LR firearms or conversion kits designed for your revolver. Remember to always prioritize safety when handling firearms, and never compromise your gun’s integrity for experimental purposes.
