CZ 457 Firing Pins
We didn't set out to become a firing pin manufacturer. We set out to find a good replacement for the CZ 457. After one design, then another, and one manufacturer after another told us no, we decided to make it ourselves.
2020 / The search began. The commitment stayed.
Pete's Pillars PP457FP / Made in USA
Nobody Wanted to Make It. So Petes Pillars Did.
In 2020, Pete's Pillars started looking for a dependable source of replacement CZ 457 firing pins. The rifle had earned an enthusiastic following, but finding the little parts that kept it running was another matter. Pete saw a straightforward need: shooters should be able to replace an important component without turning the search into a project of its own.
So he went looking for someone to make one. He worked through firing pin design after firing pin design, questioning the shape, revisiting the drawings and trying to find a manufacturer willing to take it on. The answer kept coming back the same way. Nobody wanted the job.
That could have been the end of it. Instead, it changed the direction of the business. If no one wanted to manufacture the firing pin Pete believed the CZ 457 community needed, he would make it himself.
What began as an effort to source a replacement became a part designed, manufactured and finished by Pete's Pillars. The early work led to production batches, and those batches led to the two firing pin profiles we offer today. That history is why we take this part personally. It's not another item we happened to add to the catalog. It's one of the reasons we became a manufacturer.
A Track Record We're Proud Of.
Across all of our manufacturing batches, we can count the number of defective firing pins on two hands. That's our own experience, not a claim that any manufacturer can promise perfection. What it represents is years of making the part, learning from the work and standing behind what leaves our shop. We would rather be judged on that history than on who has the loudest product description.
Choose Your CZ 457 Firing Pin
Both firing pins are manufactured by Pete's Pillars in the USA from hardened, nitrided tool steel. The difference is at the striking tip. Choose the version that fits your caliber and preferred profile, then go directly to the product listing for the details.
CZ 457 OEM-Style Firing Pin
Our factory-style tip profile, built as a finished replacement rather than a part you need to reshape. This is our recommended choice for most CZ 457 applications and for .22 WMR and .17 HMR rifles.
CZ 457 Reshaped-Tip Firing Pin
Our finished alternative tip profile for shooters who specifically want a reshaped striking tip. Developed for .22 LR CZ 457 applications, with no customer reshaping required.
Built Here. Finished Here. Stood Behind Here.
We didn't develop this firing pin to make it sound exotic. We developed it because CZ 457 owners deserved another reliable source for a part they actually use. Our production approach has three things in common across both versions.
Made by Pete's Pillars
We don't rely on a mystery supplier or private-label part. These are Pete's Pillars firing pins, designed and manufactured in the USA.
Hardened, Nitrided Tool Steel
Both versions use the material and surface-treatment approach described on our product listings, chosen for wear and corrosion resistance over the long term.
Two Finished Tip Profiles
Factory-style or reshaped. The option is yours, with clear product identification and a complete replacement part rather than a tip modification project.
Complete the Bolt Refresh
A firing pin is one piece of a larger assembly. If you're refreshing a CZ 457, these are the related Pete's Pillars parts worth knowing about.

CZ 457 Firing Pin Frequently Asked Questions
Open for fitment, tip styles, our production history and comparisons with other makers.
Which Pete's Pillars CZ 457 firing pin should I choose?
Start with the caliber and tip profile. The PP457FP OEM-style is our recommendation for most applications, particularly .22 WMR and .17 HMR. The PP457FP-T reshaped-tip is the alternative we offer for .22 LR shooters who specifically want that profile.
What makes Pete's Pillars different from Position7?
Position7 offers CZ 457 firing pin choices of its own, including competition-oriented and multi-caliber options. Those products deserve to be assessed on their individual specifications. Our distinction is our own development and production history: the search began in 2020, it led us into manufacturing, and we offer two clearly differentiated finished pins made by Pete's Pillars. We carry Position7 products as a dealer, so this isn't a claim that another good manufacturer cannot make a good part.
How does Pete's Pillars compare with Modacam?
Modacam is known for custom rimfire rifle and gunsmith work, including firing-pin modification approaches. A custom-worked component and a production replacement are different propositions; service offerings may also change. Our pins arrive as complete, finished replacement parts, with either the OEM-style or reshaped tip already made. You don't need to send in a factory pin for us to work on it.
What about DPG?
DPG is another name CZ 457 shooters encounter in the custom-rifle world. We don't have a verified, current side-by-side test of a DPG firing pin to cite, so we won't invent one. What we can speak to is our own product: hardened, nitrided tool steel, two finished profiles, in-house manufacturing and a long-running production history.
How do these compare with Whidden firing pins?
Whidden is another name shooters may encounter while researching CZ firing pins and related springs. Compare the exact part number, application, supplied components and manufacturer guidance rather than assuming all aftermarket firing pins are equivalent. Our two CZ 457 models differ by tip profile and are both finished replacements made by Pete's Pillars.
Were Pete's Pillars firing pins available in 2020?
2020 is when we first identified the sourcing problem and began looking for a replacement. It was the start of the work, not a claim that every version sold today was already in production that year. Several design attempts and unsuccessful sourcing efforts came before we decided to manufacture the part ourselves.
How many defective firing pins has Pete's Pillars had?
Across our production batches, we can count the number of defective pins on two hands. That's our own shop experience over time, not a comparison drawn from another maker's production records, and it isn't a guarantee that a defect can never occur. We stand behind the parts we manufacture.
Will a new firing pin guarantee better accuracy or cure light strikes?
No single part can guarantee either result. Ammunition, the condition of the bolt and springs, headspace, and the rifle as a whole can all matter. Our pins are designed as finished replacements with consistent manufacturing, but a specific rifle's performance should be evaluated on its own merits. Have a qualified gunsmith inspect any persistent ignition or safety problem.
Which factory part do these replace?
Our two CZ 457 firing pin listings identify CZ factory part number 5080066001 as the replacement application. Confirm the exact rifle configuration and consult the individual product pages before ordering.
Are these the same as CZ 455 or CZ 452 firing pins?
No. These pages are for the CZ 457 firing pin. Do not assume firing pins interchange simply because the rifles share other parts or have a related history.
