First Impressions of PW9 AR Pistol Caliber Firing Pin And Spring
The PW9 AR Pistol Caliber Firing Pin And Spring promises to be a vital component for AR pistol builds chambered in pistol calibers. As someone deeply invested in the AR platform and particularly pistol caliber carbines (PCCs), I was eager to see if this firing pin and spring set would live up to its claims of reliability and durability. My years of experience have taught me that even seemingly small parts can make or break a build, and a robust firing pin assembly is crucial for consistent ignition.
I needed a reliable firing pin and spring for my AR-45 build, which has seen its fair share of action and needed some TLC. After doing some research, the PW9 AR Pistol Caliber Firing Pin And Spring caught my eye due to its reported compatibility with multiple pistol calibers and the PW9 name. I was hoping this would solve some light-striking issues I was occasionally encountering, especially with harder primers.
Upon receiving the PW9 AR Pistol Caliber Firing Pin And Spring, my first impression was positive. The nitride finish looked clean and durable, and the spring felt noticeably stiffer than the one I was replacing. I appreciated the seemingly high-quality 4140 steel construction, which instilled confidence.
I considered other firing pin options, including those from more well-known brands like Brownells or CMMG. Ultimately, the price point of the PW9 AR Pistol Caliber Firing Pin And Spring and the specific claim of compatibility with multiple pistol calibers swayed my decision. The deciding factor was the positive user feedback about the Gen2 extractor tension bend, as reported by another user, which showed promise for increased reliability in my AR-45.
Initially, I was optimistic about this purchase. The PW9 AR Pistol Caliber Firing Pin And Spring seemed like a solid upgrade for my AR pistol. However, the initial user feedback mentioning limitations with Glock-style BCGs gave me pause.
Real-World Testing: Putting PW9 AR Pistol Caliber Firing Pin And Spring to the Test
First Use Experience
I first tested the PW9 AR Pistol Caliber Firing Pin And Spring at my local shooting range during a PCC-focused practice session. I installed it in my AR-45 with a Colt-style bolt carrier group. I ran approximately 200 rounds of various .45 ACP ammunition through it, ranging from standard FMJ to hollow points.
The PW9 AR Pistol Caliber Firing Pin And Spring performed flawlessly. I experienced no light strikes or failures to ignite, which was a significant improvement over my previous firing pin assembly. The increased spring tension seemed to make a difference in consistent primer ignition.
Extended Use & Reliability
After several months of use and approximately 1,000 rounds fired, the PW9 AR Pistol Caliber Firing Pin And Spring continues to perform reliably. I have not observed any noticeable wear or tear on the firing pin or spring. Regular cleaning and lubrication have kept it functioning smoothly.
The nitride finish has held up well against carbon buildup and corrosion. Maintenance involves simply wiping down the firing pin after each range session and applying a light coat of oil. So far, it has definitely outperformed my previous firing pin.

Performance & Functionality
The PW9 AR Pistol Caliber Firing Pin And Spring is designed to ensure reliable ignition in AR pistol builds. Its stronger spring and 4140 steel construction contribute to consistent performance across different pistol calibers. It excels in providing a more positive strike on primers, reducing the chance of failures to fire.
The main weakness is its limited compatibility. It is NOT suitable for Glock-style BCGs, which significantly narrows its application. It largely meets expectations for Colt-style PCCs and AR-45 builds.
Design & Ergonomics
The design is simple and functional. The firing pin is machined to precise specifications, ensuring proper fitment in Colt-style bolt carrier groups. The spring is designed with a specific tension to provide adequate force without causing excessive wear on other components.
The PW9 AR Pistol Caliber Firing Pin And Spring is straightforward to install with basic AR armorer’s tools. There is no real learning curve beyond the standard AR-15 disassembly/reassembly process.
Durability & Maintenance
The use of 4140 steel and a nitride finish suggests good longevity. With proper maintenance (regular cleaning and lubrication), it should last for thousands of rounds. It’s easy to clean using standard gun cleaning solvents and brushes.
Accessories and Customization Options
This particular product doesn’t require additional accessories, as it’s a self-contained firing pin and spring assembly. However, it’s worth noting that if you are upgrading your entire bolt carrier group, you might consider other enhanced BCG components. You may want to add a spare extractor roll pin for maintenance purposes.
