What is the difference between FN 5.7 mk1 and MK2?

The FN 5.7 is a series of semi-automatic pistols developed by FN Herstal in Belgium. The MK1 and MK2 are two different models within this series. Here are the main differences between the FN 5.7 MK1 and MK2:

1. **Design and Ergonomics**: The MK2 features improved ergonomics compared to the MK1. It has changes in the grip texture and contour for better handling and user comfort.

2. **Sights**: The MK2 typically comes with adjustable sights as a standard, whereas the MK1 might have different sighting options. Some MK2 variants also feature a more robust sight system.

3. **Accessory Rail**: The MK2 often includes an enhanced accessory rail, making it more adaptable for mounting tactical lights or lasers.

4. **Trigger Guard**: The MK2’s trigger guard is designed with better adaptability for use with gloves, compared to the MK1.

5. **Finish and Materials**: The MK2 may have an updated finish and slight material changes to enhance durability and corrosion resistance.

Is 5.7 stronger than 9mm?

The comparison between 5.7x28mm and 9mm (9x19mm Parabellum) rounds depends on several factors and the specific context in which you’re measuring “strength.” Here are some general differences:

1. **Ballistics and Velocity**:
– The 5.7x28mm round is known for its high velocity, typically around 2,000 to 2,800 feet per second (fps), which is higher than the typical 1,000 to 1,300 fps of a 9mm round.
– The higher velocity of the 5.7 can result in better penetration capabilities, especially against body armor, which is one of the reasons it was designed.

2. **Stopping Power**:
– The 9mm round generally offers greater stopping power due to its larger bullet size and weight, often ranging from 115 to 147 grains compared to the typical 31 to 40 grains of a 5.7 bullet.
– For self-defense or applications where penetration through barriers isn’t the main concern, the 9mm might be considered more effective due to the energy it delivers upon impact.

3. **Recoil and Control**:
– The 5.7x28mm generally produces less recoil, making it easier to control and allowing for faster follow-up shots, which can be advantageous in a tactical situation.

4. **Capacity and Size**:
– Firearms chambered for the 5.7 round often have higher magazine capacities compared to their 9mm counterparts due to the smaller size of the 5.7 cartridge.

5. **Availability and Cost**:
– 9mm ammunition is more widely available and generally cheaper, making it a popular choice for civilians and law enforcement use.

Whether one is “stronger” than the other depends on the intended use. If you’re seeking high velocity and penetration, particularly against armor, the 5.7x28mm might be more suitable. However, if you prioritize stopping power and availability, the 9mm may be preferable.

What is the difference between the FN 5.7 MK2 and MK3?

1. **Design Updates**: The MK3 generally features design improvements over the MK2. These include ergonomic enhancements and updates in styling to provide a more modern look.

2. **Weight and Dimensions**: The MK3 may have slight changes in weight or dimensions due to design adjustments. These changes can affect the balance and handling of the pistol.

3. **Enhanced Features**: The MK3 often includes upgraded features such as improved sights or accessory rails, which may not be present or as refined on the MK2.

4. **Materials and Finish**: There might be differences in materials and the finish used, with the MK3 potentially having more durable or aesthetically pleasing options.

5. **Ergonomics and Feel**: The MK3 may have changes in grip texture or shape, resulting in a different feel when handling compared to the MK2.

These differences are typical of incremental updates that focus on improved functionality, user comfort, and aesthetics. For specific details, consulting official FN materials or reviews would provide precise information.
