Frequently Asked Questions

What are common hidden problems with the Sig Sauer P320?

Early Sig Sauer P320 models had a drop safety issue where they could fire if dropped at a rearward angle due to trigger system inertia. Sig addressed this with a voluntary upgrade program that modifies fire control parts for increased safety.

Why should Springfield Armory XD Gen 1 pistols be inspected carefully?

Springfield Armory XD Gen 1 pistols can develop trigger failures over time due to wear in the grip safety linkage and repeated impact on striker assembly roll pins, potentially leading to light primer strikes.

What potential issues exist with Taurus Millennium Pro and PT111 pistols?

Early Taurus Millennium Pro and PT111 pistols have faced scrutiny regarding drop safety, with some models involved in class-action lawsuits alleging they could fire if dropped. Internal components and tolerance issues can also lead to gritty triggers and reliability problems.

Are there specific concerns with older Glock .40 S&W models like the G22 and G23?

Yes, Gen 2 and early Gen 3 Glock 22 and 23 models, particularly in .40 S&W, may have frame and locking block design issues. Inspection around the locking block, pins, and rails is recommended due to the original two-pin setup.
