The term "38 revolver no hammer" typically refers to a .38 caliber revolver that lacks an externally visible hammer. These firearms, often called hammerless revolvers, utilize a different firing mechanism than traditional hammer-fired revolvers. Understanding their mechanics, advantages, and disadvantages is crucial for anyone considering owning or handling one.
How Hammerless Revolvers Work
Unlike revolvers with exposed hammers that require manual cocking, hammerless revolvers employ an internal hammer system. The hammer is concealed within the frame of the gun, and the trigger directly interacts with the hammer mechanism. This usually involves a double-action-only (DAO) system.
Double-Action Only (DAO)
In a DAO revolver, pulling the trigger performs two actions simultaneously:
- Cocking the hammer: The trigger's initial movement cocks the internal hammer.
- Releasing the hammer: Continued trigger pull releases the cocked hammer, firing the round.
This means each shot requires a full trigger pull, eliminating the option for single-action shooting (cocking the hammer separately before pulling the trigger).
Advantages of Hammerless .38 Revolvers
-
Concealed Carry: The lack of an external hammer makes these revolvers smoother and easier to conceal, particularly in inside-the-waistband (IWB) holsters. The reduced chance of snagging on clothing is a significant benefit.
-
Increased Safety: The absence of a protruding hammer minimizes the risk of accidental discharge caused by snagging or impact. This is a considerable advantage in potentially dangerous situations.
-
Simpler Operation: While not necessarily simpler in mechanism, the DAO operation simplifies the handling process, especially for novice shooters. There's no need to learn the nuances of single-action and double-action firing.
Disadvantages of Hammerless .38 Revolvers
-
Heavier Trigger Pull: The double-action-only trigger pull is generally heavier and requires more force than a single-action trigger pull. This can affect accuracy and shooting speed, especially for individuals with weaker hands or less shooting experience.
-
Longer Trigger Travel: The DAO system typically involves a longer trigger travel distance, further impacting speed and potentially accuracy.
-
Potential for Misfires: While rare, potential mechanical issues within the internal hammer system can lead to misfires. Regular maintenance and cleaning are vital for reliable function.
Choosing a Hammerless .38 Revolver
The decision to purchase a hammerless .38 revolver should be based on individual needs and preferences. Consider the following factors:
-
Intended Use: Concealed carry? Home defense? The use case will heavily influence the type of firearm that is best suited to the task.
-
Shooting Experience: Beginners might find the heavier trigger pull of a DAO more challenging, while experienced shooters might appreciate the increased safety aspects.
-
Maintenance: Regular cleaning and maintenance are crucial for the reliable operation of any firearm, especially a hammerless revolver with its internal mechanism.
Ultimately, the best .38 revolver, whether hammerless or not, is the one that best fits your individual needs and shooting style. It is highly recommended to visit a reputable gun store, handle various models, and if possible, test fire different options before making a purchase. Remember to always prioritize safety and follow all local and federal firearm regulations.
