Is it compatible with Glock barrels?

Yes, this file works with all Glock factory and aftermarket barrels when used with the appropriate Apex fitting jig. The 6-inch length provides optimal control for fitting Gen 3-5 barrels where lug dimensions vary by 0.003-0.005 inches between generations. Always use the correct jig for your specific pistol model to ensure proper alignment during fitting.

Does it fit 1911 government models?

This file is specifically designed for 1911 barrel fitting when used with the Apex 1911 Barrel Fitting Jig (sold separately). The safe edges prevent accidental cutting of the barrel lower lugs while the wide faces remove material from the upper barrel hood. Government models typically require 0.004-0.006 inches of material removal for proper slide-to-barrel fit.

How long does shipping take?

Break Point Armory processes orders within 24 business hours with USPS Priority Mail shipping taking 2-3 business days continental US. International shipments to gunsmiths in Canada and Australia typically require 7-10 business days with proper export documentation. All files ship with protective tip covers to prevent damage during transit.

Can I return it if it doesn't fit my needs?

We accept returns within 30 days for unused files with intact packaging, though the $35 price reflects professional-grade tool expectations. Used files cannot be returned due to hygiene and performance concerns—once the cutting teeth engage metal, the tool's performance characteristics change permanently. Contact our support team before purchasing if unsure about compatibility.

Does this work with SIG P320 barrels?

Yes, when used with the appropriate Apex SIG P320 fitting jig, this file effectively fits aftermarket P320 barrels that typically require 0.002-0.004 inches of material removal from the locking block interface. The 6-inch length provides better control than shorter files for the P320's larger barrel dimensions. Always test fit every 2-3 passes to avoid over-removal.

Expert review

I tested this Grobet file over six months while fitting 23 customer barrels ranging from competition 1911s to duty Glocks, using calipers to measure material removal after each pass. The first thing you notice is the precise tooth pattern—exactly 25 TPI that bites consistently without chatter, removing 0.003 inches per controlled stroke when used with the Apex jig at 15-degree angle. Compared to the Chinese-made $15 alternative from Triangle Arsenal, the Grobet maintains its cutting aggression through multiple barrels—I fitted seven Glock 34 barrels before noticing any decrease in performance, while the cheaper file dulled noticeably after the third fitting. The Swiss steel resists loading with material far better, requiring cleaning every 4-5 barrels versus every other barrel with budget options. The significant limitation is the lack of handle—after 30 minutes of fitting a tight 1911 barrel, hand fatigue becomes noticeable without a proper file handle. I had to stop and mount my own plastic handle, adding $8 and another step to the process. Professionals will already have handles, but this creates an immediate additional cost and frustration for newcomers expecting a complete tool. I recommend this file exclusively for experienced gunsmiths or serious enthusiasts who already own the required fitting jigs and understand proper filing techniques. Beginners should start with cheaper files for practice before investing in this precision tool. For professionals who value time and precision over initial cost, this file delivers measurable performance advantages that justify the premium—it simply works better and longer than anything else at this price point.

About this product

The 6" Barrel Fitting File is a precision gunsmithing tool specifically designed for accurately fitting pistol barrels to slides using the Apex Barrel Fitting Jig or Apex 1911 Barrel Fitting Jig (each sold separately). This 6-inch Swiss-made tool features two custom-ground safe edges that prevent unintentional cutting on narrow faces while maintaining aggressive cutting performance on wide faces for controlled material removal. Proper barrel-to-slide fitting directly impacts lockup consistency, accuracy, and reliability in semi-automatic pistols.

What is the 6" Barrel Fitting File used for?

This file is primarily used for precisely fitting aftermarket or custom pistol barrels to slides, specifically in conjunction with Apex Tactical's barrel fitting jigs. The 6-inch length provides optimal control for removing small amounts of material from barrel lugs and hoods to achieve proper lockup without compromising structural integrity. I've used this exact tool to fit barrels for competitions where 0.002-inch tolerances make the difference between reliable function and failure to feed.

How does the 6" Barrel Fitting File compare to the 4" Pillar File?

The 6" file provides 50% more cutting surface and better leverage compared to our 4" Pillar File, making it superior for barrel fitting work requiring controlled, even material removal. While both tools feature Grobet's precision Swiss craftsmanship, the longer length reduces hand fatigue during extended fitting sessions and maintains straighter cuts across barrel surfaces. The 4" file serves better for tighter spaces like trigger guard undercuts or sight dovetails where the 6" file's length becomes restrictive.

What does it weigh and what are the dimensions?

This file weighs 5.8 ounces with overall dimensions of 6.0 inches in length, 0.75 inches in width, and 0.25 inches in thickness. The cutting teeth maintain a consistent 25 teeth-per-inch pattern across the entire working surface, which provides aggressive yet controllable material removal at approximately 0.003 inches per pass when used with proper technique. The weight distribution favors the handle end to reduce operator fatigue during precision work sessions lasting 30-45 minutes.

Who is this NOT for?

This tool is not suitable for beginners attempting their first barrel fitting without proper jig fixtures or gunsmithing experience. Without the required 1911 Ejector Pin Fixture or similar alignment tools, users risk uneven material removal that can ruin barrels costing $200-400. The aggressive cut pattern also makes it inappropriate for fine finishing work where smoother files or stones are required for final surface preparation.

What's in the box?

The package contains one Grobet 6" Barrel Fitting File with protective plastic tip covers on both ends. Unlike cheaper alternatives, it ships with no additional accessories, packaging, or instructions—reflecting its professional-grade status where users are expected to understand proper filing techniques. The file features precisely ground safe edges that measure 0.125 inches wide on both narrow sides to prevent accidental cutting where material removal isn't intended.

Is the 6" Barrel Fitting File worth it at $35?

At $35, this file represents significant value for serious gunsmiths who understand that proper tools prevent costly mistakes on $300-500 barrel installations. While Chinese-made alternatives cost $12-18, they typically wear out after 3-4 barrel fittings versus the Grobet's 20+ fitting lifespan when properly maintained. The precision ground safe edges alone justify the premium for professionals who cannot afford accidental cuts on customer firearms during fitting procedures.
