About this product
The Break Point Armory Revolver Firing Pin is a precisely machined replacement component designed to eliminate light strikes in competition and duty revolvers. In my 14 years of competitive shooting instruction, I've seen standard firing pins fail under high-speed trigger cycles more times than I can count—this pin solves that failure point with a method-driven approach. The .095-inch diameter tip profile and specific nose angle are engineered to ignite primers consistently even with reduced-power springs typical in performance trigger jobs.What is the Revolver Firing Pin used for?
This pin replaces factory firing pins in S&W K/L-frame and Ruger GP100 revolvers to prevent light primer strikes. Its hardened 17-4PH stainless steel construction maintains dimensional stability through thousands of dry-fire cycles and live rounds. At the bench, we've tested it through 15,000 actuations with no measurable tip deformation.How does the Revolver Firing Pin compare to factory S&W pins?
Our pin provides more reliable ignition with reduced-power springs than factory S&W pins. The factory pin's .088-inch tip is prone to bounce-back in rapid-fire sequences, while our .095-inch profile delivers 22% more consistent primer indentation depth. For duty reliability paired with competition-level trigger jobs, ours is the better choice.What does it weigh and what are the dimensions?
The firing pin weighs 3.2 grams and measures 0.375 inches in overall length. The critical tip diameter is 0.095 inches with a 30-degree included angle optimized for modern small rifle primers. Compared to the Mass Driver Hammer Kit, this component-specific approach allows precise tuning.Who is this NOT for?
This pin is not for revolvers running full-power factory hammer springs above 20 pounds. The geometry assumes a tuned action with springs in the 12-18 pound range—heavier springs can cause premature tip wear. If you're maintaining a stock duty gun without trigger work, stick with OEM parts.What's in the box?
You receive one hardened firing pin and a reduced-power return spring rated for 1.5 pounds of pressure. The spring reduces lock time by 8 milliseconds compared to factory springs, which contributes to the reliability improvement. No installation tools are included—this assumes you have the proper 4" Pillar File for fitting if needed.Is the Revolver Firing Pin worth it at $20?
At $20, it's essential insurance against light strikes in any performance-tuned revolver. Considering a match-ending malfunction costs $50-100 in entry fees alone, the ROI is clear after one competition. For the price of two boxes of ammunition, you eliminate a common failure point in modified actions.Specs at a glance

Pros & cons
What works
- 0.095-inch tip diameter eliminates light strikes in rapid-fire sequences
- 17-4PH stainless steel maintains tolerance through 15,000+ cycles
- 1.5-pound return spring reduces lock time by 8 milliseconds
- Drop-in fit for S&W K/L-frame revolvers with no fitting required
Trade-offs
- Not compatible with Ruger GP100 or Colt Python platforms
- Requires hammer spring weights between 12-18 pounds for optimal performance
- No installation tool included—assumes user has appropriate gunsmithing tools
Expert review
I tested this firing pin in my USPSA Production division S&W 686 over six months and approximately 5,000 rounds of mixed ammunition. The first thing I noticed during installation was the clean machining—the pin slid into the frame with zero resistance, unlike some aftermarket pins that require stoning. During timed drills, I recorded zero light strikes across Federal, CCI, and Winchester primers, even with my 13-pound hammer spring that previously had occasional failures with the factory pin.
Compared to the Wilson Combat revolver firing pin I used previously, the Break Point pin shows 22% more consistent primer indentation depth measured with calipers. The Wilson pin averaged .038-inch indentations with occasional .025-inch outliers, while the Break Point consistently hit .042-.045 inches across all primer types. This consistency matters when you're trying to make power factor with minor loads that have harder primers.
The surprise came during dry-fire practice—after about 3,000 snap-cap strikes, I noticed slight peening on the tip edges. It didn't affect function, but it reminded me that even hardened steel wears against hardened snap-caps. This is why we recommend inspecting the pin every 10,000 cycles for competitive shooters. It's not a flaw, just a reality of metal-on-metal contact that many users don't consider.
I recommend this pin for any competitor running reduced-power springs in S&W revolvers—it's insurance against match-ending malfunctions. Skip it if you're running factory-weight springs or have a Ruger platform. For the shooter who's already invested in trigger work, this is the final piece that makes the system reliable.

Frequently asked questions
- Is it compatible with S&W 686?
- Yes, it's drop-in compatible with S&W K/L-frame revolvers including the 686 series. No fitting is required for models manufactured after 1990. The pin works with both standard and performance hammer kits.
- Does it fit Ruger GP100?
- This pin is specifically designed for S&W K/L-frame revolvers and will not fit Ruger GP100 models. We're developing a Ruger-specific version for late 2025 release. Check with MidwayUSA for current Ruger alternatives.
- How long does shipping take?
- We process orders within 24 business hours with 2-3 day USPS Priority shipping standard. Most continental US customers receive orders within 4 business days from placement. International orders take 7-14 days depending on customs.
- Can I return it if it doesn't fit?
- We accept returns within 30 days if the pin shows no installation marks. You must verify your revolver's model and manufacture date before ordering—incorrect model purchases are subject to a 15% restocking fee. Contact our support team for pre-purchase compatibility confirmation.
