About
What it is, and why it matters
The Bauer 25 Automatic is an American-made stainless steel copy of the FN Baby Browning, a .25 ACP vest-pocket pistol. Produced in Fraser, Michigan from 1972 to 1984, it was one of the first semi-automatic pistols manufactured entirely from stainless steel, using precision-machined 416 stainless investment castings with hand-fitted internal parts. The blowback-operated pistol fed from a six-round detachable box magazine and used integral fixed sights machined into the slide.
Founder Robert Bauer had previously worked for DeSantis Holsters before setting up his Michigan plant to build a stainless-steel update of the legendary Baby Browning; after his death in 1984 the line was rebranded the Fraser-25, and the factory burned to the ground in 1986.
The fire position of the thumb safety doubles as the takedown position; the barrel rotates clockwise roughly 45 degrees to disassemble. Grips were offered in synthetic white pearl (most common), walnut, black pearl, and pink pearl.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
