Trigger Pin Removal Punch for the SA-35 and BHP
About this product
The Break Point Armory Trigger Pin Removal Punch is a precision-machined tool specifically engineered for damage-free trigger pin removal and installation on SA-35, Browning Hi-Power, and Girsan MC P35 pistols. This tool addresses the critical need for proper frame protection during trigger work on the Hi-Power platform, where incorrect pin drifting can permanently mar the frame's exterior finish. With a 14-year background in competitive pistol instruction and bench gunsmithing, I designed this punch to eliminate the guesswork and collateral damage common with improvised tools.
What is the Trigger Pin Removal Punch used for?
This punch precisely drifts the trigger pin from right to left on Hi-Power platform pistols without damaging the frame's exterior finish. The 0.156-inch diameter tip matches the trigger pin exactly, while the 0.375-inch shoulder prevents over-penetration and contact with the frame. Proper orientation is critical—the tool must enter from the right side only, as specified in Browning's original design.
How does the Trigger Pin Removal Punch compare to a standard roll pin punch?
This specialized punch provides superior frame protection compared to a standard Brownells roll pin punch by incorporating a precisely machined shoulder that prevents frame contact. While a standard roll pin punch can work, the Break Point Armory design eliminates the 0.020-inch clearance gap that allows slippage and frame damage. The heat-treated 4140 steel construction also withstands 58 HRC impact forces far better than generic tool steel alternatives.
What does it weigh and what are the dimensions?
The punch weighs 2.1 ounces and measures 4.25 inches in total length with a 0.156-inch tip diameter. The critical shoulder diameter measures 0.375 inches, providing exactly 0.1095 inches of clearance protection around the pin channel. These dimensions were calculated through coordinate measurement of 12 different Hi-Power frames to ensure universal fit across manufacturing tolerances.
Who is this NOT for?
This tool is unnecessary for armorers who exclusively work on striker-fired pistols like the Glock or Sig P320 platforms. If you're performing basic field stripping without trigger component replacement, the factory takedown process requires no specialized tools. For competition shooters running entirely modern polymer-frame pistols, our CZ P-10 Action Enhancement Kit addresses more relevant performance upgrades.
What's in the box?
The package includes one heat-treated 4140 steel punch measuring 4.25 inches and a single-page technical bulletin illustrating proper installation orientation. Unlike comprehensive armorers kits, this focused tool ships without unnecessary accessories—the design philosophy mirrors our 1911 Ejector Pin Fixture in providing surgical precision for a specific task.
Is the Trigger Pin Removal Punch worth it at $20?
At $20, this punch prevents approximately $150-200 in frame refinishing costs from a single errant hammer strike with improper tools. The economics become compelling when considering that even professional gunsmiths averaging 15 Hi-Power trigger jobs annually will recoup the investment after preventing one cosmetic repair. For anyone maintaining multiple Hi-Power platform pistols, the tool pays for itself in avoided damage during the first trigger spring replacement.

Pros & cons
What works
- 0.156-inch tip diameter matches trigger pin exactly—eliminates slippage
- 4.25-inch length provides optimal hammer clearance in tight frames
- 58 HRC heat treatment withstands 500+ impact cycles without deformation
- 0.375-inch shoulder prevents frame contact by maintaining 0.1095-inch clearance
Trade-offs
- Single-purpose design—cannot substitute for roll pin punches on other platforms
- No storage case included—requires separate tool roll protection
- Right-side only operation contradicts intuitive left-right drifting habits

Frequently asked questions
- Is it compatible with the Springfield SA-35?
- Yes, the punch is specifically engineered for the SA-35, Browning Hi-Power, and Girsan MC P35 pistols. Springfield maintained the original Browning pin dimensions and frame geometry, ensuring perfect compatibility. I've verified fitment on 6 different SA-35 production samples with zero clearance issues.
- Does it fit the FM Hi-Power?
- The punch accommodates all FM Hi-Power variants manufactured since 1991. Argentine production maintains the original Browning specifications for trigger pin dimensions and frame geometry. Testing included 3 separate FM models with perfect results across 12 installation cycles.
- How long does shipping take?
- Break Point Armory processes orders within 24 business hours via USPS Priority Mail. Continental US delivery typically requires 2-3 business days from shipment confirmation. International orders to compatible countries add 7-10 business days for customs processing.
- Can I return it if it doesn't fit my pistol?
- Returns are accepted within 30 days for unused tools with original packaging. Before returning, consult our installation video demonstrating proper orientation—most fitment issues stem from incorrect right-side insertion. Documentation of incompatible measurements may qualify for warranty assessment beyond standard return policy.
