Review on 🔫 M12 Stapler with 3/8 inch Crown by Jerry Delic

This portable stapler was purchased for a job that ran over 5,500 staples. While not perfect, it saved my hand from hand staplers. Of the 5,500 staples, about 500 staples/staples probably failed. I think the stapling failed mainly because the shackle hole got too big or out of spec. In theory, the hole should only be big enough for a staple to fly out, but it should be small enough for the staple blade to hit the staple squarely and knock the staple out in a perfectly straight path. The opening is slightly larger than a staple by design, which I believe is about 1-1/4 (125%) of a staple. The staple holder/tensioner (the part you pull out from the back to add extra staples to your stapler) also acts as a hole adjuster. I've noticed that when the opening becomes 1-1/2 staples, the seam fails. I was able to temporarily fix the problem by resetting the retainer/spanner. Milwaukee needs to be redesigned to allow for a permanent opening or have a mechanism to adjust how far the retainer/spanner goes in. I think an adjustable mechanism is better because the material wears out over time so the hole gets bigger over time rendering the stapler useless. In every way (except the price tag) this stapler outperforms any manual stapler. If you have the money and do a lot of field sewing, I would recommend getting one.
