Duration: 50:06

This live Q&A session features firearms instructors discussing various calibers, firearms, and accessories. Topics include the viability of .357 SIG, recommendations for surplus carry pistols like the Makarov, and the versatility of .300 Blackout for hunting and self-defense. They also delve into the challenges of AR-15 accuracy with .300 Blackout, the legal landscape surrounding firearms and suppressors, and the performance of specific firearms like the FN 5.7 and the FN SCAR 17. The discussion also touches on optics, barrel profiles, and the complexities of ATF regulations.

Quick Summary

The .357 SIG cartridge, while a good concept for bringing .357 Magnum-like performance to an automatic pistol, is largely considered obsolete due to its expense and limited availability compared to common straight-walled pistol cartridges. Its bottlenecked case design also doesn't necessarily guarantee better feeding reliability compared to straight-walled options.

Frequently Asked Questions

What are the pros and cons of the .357 SIG cartridge?

The .357 SIG was designed to offer .357 Magnum-like performance in a semi-automatic pistol. While it provides good ballistic performance, it's often criticized for being expensive to shoot and less readily available than common straight-walled cartridges. Its bottlenecked case design also doesn't necessarily guarantee better feeding reliability compared to straight-walled options.

What is the best surplus pistol for concealed carry?

The Makarov PM is frequently recommended as an excellent surplus pistol for concealed carry due to its reliability and affordability, often found for under $300. However, thorough cleaning is crucial, especially in the firing pin channel, to prevent malfunctions like slam-firing or failure to fire, often caused by cosmoline residue.

What are the best .300 Blackout rounds for hunting whitetail deer?

For hunting whitetail deer with .300 Blackout, supersonic rounds are generally recommended for humane kills at typical hunting distances. Ammunition like Lehigh Controlled Chaos and Hornady Black 110gr have shown effectiveness on game such as hogs, indicating good terminal performance for medium-sized game.

Are AR-15 pencil barrels accurate enough for civilian use?

Yes, for most civilian shooters who don't engage in sustained rapid fire, AR-15 pencil barrels offer sufficient accuracy. They provide a significant weight reduction without a noticeable decrease in precision compared to heavier profiles, provided the barrel is properly stress-relieved and not burdened by excessive accessories.

Can civilians legally carry PCCs with suppressors out-of-state?

Civilians can generally travel with suppressors across state lines as long as their final destination permits their use, as suppressors are not classified as firearms by the ATF. However, stopping in a state where suppressors are illegal can result in penalties. It's crucial to ensure compliance with the laws of the destination state.
