The FEG 37 is a pistol manufactured by FEG (Fegyver és Gépgyár), a Hungarian firearms company. Determining the exact caliber requires specifying the model of FEG 37, as FEG produced several variations of the pistol chambered in different calibers. This is crucial because simply stating "FEG 37" is insufficient for identifying the correct ammunition.
Understanding FEG's Model Naming Conventions: FEG's model designations weren't always consistently clear. A model number might not immediately reveal the caliber. For example, a "FEG 37" might be further identified with suffixes, prefixes, or additional markings indicating the cartridge it uses.
Common Calibers Found in FEG Pistols Similar to the "FEG 37":
While a definitive answer hinges on identifying the specific FEG 37 model, some common calibers used in FEG pistols of that era include:
-
9mm Parabellum (9x19mm): This is a very common pistol caliber worldwide and was frequently used in FEG firearms. It's the most likely candidate if you have a general "FEG 37" without further model identification.
-
.380 ACP (9x17mm): Another popular and relatively smaller caliber, often found in smaller self-defense pistols.
-
.22 Long Rifle (.22 LR): While less likely for a pistol designated as a "37", some FEG models utilized this caliber.
How to Identify Your FEG 37's Caliber:
The most reliable method to determine your FEG 37's caliber is to:
-
Visually Inspect the Weapon: Look for markings on the slide, barrel, or frame. These markings should clearly state the caliber. The caliber will often be printed or stamped directly on the gun.
-
Check the Owner's Manual: If you have the original owner's manual, it will definitively specify the caliber.
-
Consult a Firearms Expert: A gunsmith or experienced firearms professional can quickly and safely identify the caliber of your pistol. This is highly recommended if you are unsure. Never attempt to fire a firearm unless you are 100% certain of the caliber and ammunition compatibility.
Safety First:
Incorrect ammunition is extremely dangerous and can lead to serious injury or death. Always double-check your ammunition before firing any firearm. Never assume the caliber based on a model number alone. Use the methods described above to positively identify your FEG 37's caliber before handling any ammunition.
