Description
Wilson Combat's firing pin stop for Series 80 1911 pistols is built from what they call Bullet Proof bar stock steel, which means it's completely machined rather than stamped like cheaper alternatives. The corners are carefully radiused during manufacturing to eliminate stress points and dramatically improve strength and longevity. This isn't a replacement part you install and forget about; it's an upgrade that fundamentally improves how your slide's internal systems work together.
What Makes the Bullet Proof Design Different
Most factory firing pin stops are thin stamped parts that can bend under heavy use or create binding issues with your extractor. Wilson Combat's Bullet Proof version is substantially wider and thicker, which prevents the extractor from turning excessively during firing. This directly improves extraction reliability, which is why competitive shooters and people running heavy loads specifically reach for parts like this. The blued finish provides both protection and that classic appearance that complements any 1911.
Fitting and Installation
This part does require minor fitting to your particular pistol, which is standard across quality aftermarket firing pin stops. Tolerances vary between manufacturers and even between individual guns, so a gunsmith will test-fit the part and make any necessary adjustments. The effort is worth it because a properly fitted firing pin stop eliminates movement while under recoil, which translates to better reliability and more predictable performance.
Series 80 Specific Details
This stop is specifically designed for Series 80 pistols, meaning it works with guns that have the Series 80 firing pin safety system. If your pistol is a Series 70 (without the firing pin block), you'll need a different part. Always confirm your gun's series before ordering.

Frequently Asked Questions
Will this firing pin stop work with my Series 70 1911?
No, this part is specifically designed for Series 80 guns with the Series 80 firing pin safety system. Series 70 pistols require a different firing pin stop. Make sure to confirm which series your gun is before ordering, as the internal systems are different between them.
Do I need a gunsmith to install this firing pin stop?
Yes, we recommend having a qualified gunsmith handle the installation. While these parts are intended to be drop-in, manufacturing tolerances between different gun makers mean most require at least some minor fitting to your specific pistol for a proper, snug fit.
What's the difference between Bullet Proof and standard firing pin stops?
Wilson Combat's Bullet Proof parts are fully machined from bar stock steel with radiused corners, making them many times stronger than typical stamped factory parts. They're also oversized and thicker to reduce extractor movement and provide better reliability, particularly during heavy use or with heavy ammunition loads.
Will this work with my Commander model?
Yes, this Series 80 firing pin stop is compatible with Commander models that have the Series 80 firing pin safety system. Always verify that your specific gun is indeed a Series 80 Commander before purchasing, as some Commanders come in either series configuration.
