Frequently Asked Questions

Which early Sig Sauer P320 models are prone to drop safety issues?

Early production Sig Sauer P320 models, manufactured before the voluntary upgrade program, can exhibit a safety problem where they might fire when dropped at a rearward angle. This is due to the trigger system moving from inertia. Owners should check Sig's website for upgrade eligibility.

What are common failure points in Springfield Armory XD Gen 1 pistols?

Springfield Armory XD Gen 1 pistols can develop trigger failures over time as the grip safety linkage wears. Additionally, roll pins in the striker assembly may deform from repeated impact, leading to light primer strikes and reduced reliability.

Are Taurus Millennium Pro and PT111 pistols safe to carry?

Early Taurus Millennium Pro and PT111 models, particularly from the mid-2010s, have been associated with drop safety issues where they could fire if dropped. While Taurus settled a class action lawsuit, it's advisable to be aware of this potential and ensure any existing models have been addressed.

What maintenance is critical for Kimber Ultra Carry and Pro Carry aluminum frame 1911s?

Kimber Ultra Carry and Pro Carry models with aluminum frames require diligent maintenance. The faster slide cycle inherent in shorter barrels can lead to increased wear. Regularly updating recoil springs and carefully inspecting and maintaining the feed ramp are essential for reliable function.
