This video explains the fundamental differences between internal hammer-fired firearms and striker-fired firearms. It details how each mechanism functions during the trigger pull, highlighting the energy generation and sear release processes. The presenter, TheYankeeMarshal, offers insights into which system might be preferable for different applications, such as competition versus self-defense.

Quick Summary

Internal hammer firearms, often double-action revolvers, use the trigger pull to both cock and release the hammer. Striker-fired firearms use the trigger pull solely to release a pre-cocked striker. While striker-fired offers faster triggers for competition, internal hammers are often preferred for self-defense due to robustness and double-strike capability.

Frequently Asked Questions

What is the primary difference in how internal hammer and striker-fired firearms operate?

Internal hammer firearms (like double-action revolvers) use the trigger pull to both cock and release the hammer. Striker-fired firearms use the trigger pull solely to release a pre-cocked striker, which is already under spring tension.

Can striker-fired firearms perform a 'double strike' if a round fails to fire?

No, striker-fired firearms typically do not have a double-strike capability. If a round fails to ignite, you must manually cycle the slide to reset the striker and attempt another shot.

Which type of firearm is generally considered better for competition shooting?

For competition shooting where speed is paramount, striker-fired firearms are often preferred due to their lighter and faster trigger pulls, which allow for quicker follow-up shots.

Why might an internal hammer firearm be preferred for self-defense?

Internal hammer firearms, particularly revolvers, are often favored for self-defense due to their perceived robustness, reliability, and the ability to re-strike a dud round by simply pulling the trigger again.

Are 'hammerless' revolvers truly hammerless?

No, revolvers referred to as 'hammerless' actually have an internal hammer that is not exposed with a spur. They are typically double-action only, meaning the hammer cannot be manually cocked for single-action firing.
