This fixture is a dedicated armorer’s tool for manually fitting replacement barrels into Smith & Wesson M&P and M&P M2.0 pistols using a hand file. It solves the problem of inconsistent barrel-to-slide lockup by holding the barrel in two precise orientations: top-down for hood length trimming, and with the hood against the base for trimming the bottom lockup surface. Intended for gunsmiths and armorers who need repeatable alignment during hand filing.
Compatibility
- Smith & Wesson M&P (classic) barrels
- Smith & Wesson M&P M2.0 barrels
- Does not fit Shield, Shield Plus, or Compact models without barrel profile verification
Key Features
- Two fixed orientations: top-down for hood length, base-against for lockup surface
- Polymer construction – lighter than aluminum versions with equivalent dimensional stability
- Hand-file only – not designed for use with power tools or mill fixtures
- Compact footprint for bench or field use
Install Difficulty: 2/5
Requires a hand file (6″ barrel file recommended). No disassembly of the pistol needed. Suitable for intermediate-level armorers.
FAQ
Are the 3D Poly tools as good as the aluminum versions?
No, the 3D Poly versions of our tools are generally better than our aluminum tools. They provide consistent alignment with less risk of marring the barrel finish.
What file do I need for this fixture?
Use a 6″ barrel fitting file (sold separately). A standard flat file will work but may require more passes to achieve proper fit.
Will this work with M&P 2.0 Compact barrels?
Yes, it works with M&P 2.0 full-size and Compact barrels. Verify barrel profile matches the fixture’s slot dimensions before trimming.
