What Is .25 ACP?
The .25 ACP (Automatic Colt Pistol) was designed by John Moses Browning and introduced in 1905 with the FN Model 1905 pocket pistol. Colt followed with its Model 1908 Vest Pocket, and the cartridge went on to be chambered in a long list of small pistols worldwide. In Europe it is usually labeled 6.35mm Browning (or 6.35×16mmSR); in the United States it is also sold as .25 Auto. All three names describe the same round.
Key dimensions: bullet diameter 0.251 inches, case length 0.615 inches, and an overall length of about 0.910 inches. It is a semi-rimmed, straight-walled case, and SAAMI lists its maximum average pressure at 25,000 psi. Typical factory loads use 35gr–50gr bullets: 50gr FMJ at roughly 760 fps and 35gr–45gr hollow points at roughly 815–900 fps.
The semi-rimmed design is part of why the cartridge was chosen for very small pistols — it feeds reliably from short single-stack magazines and works with simple blowback actions. Many .25 ACP pistols are no larger than a palm.
Firearms Chambered in .25 ACP
- Historic vest-pocket pistols — FN 1905/1906, Colt Model 1908 Vest Pocket, Baby Browning, and the Walther Model 9.
- Later pocket pistols — Beretta 950 and 21A Bobcat, the Bauer .25 Auto, and several small pistols produced by U.S. makers through the late 20th century.
- Current and recent production — fewer new pistols are chambered in .25 ACP than in .380 ACP or .32 ACP, but a substantial number of existing pistols remain in use, which keeps factory ammunition in production.
Handling and Reliability Notes
Small blowback pistols are sensitive to ammunition in ways full-size pistols are not. Rim engagement, overall length, and bullet shape all affect how a short magazine presents the next round, and some older pistols were designed around round-nose FMJ only. Manufacturers' manuals often list the loads a pistol was tested with. Many of these pistols also have no firing-pin block, so carrying with a round chambered depends on the specific design — read the manual for the pistol in hand.
How .25 ACP Is Used
- Shooting existing pocket pistols — the main reason people buy .25 ACP today; many of these pistols are inherited or collected.
- Range practice with 50gr FMJ.
- Defensive carry in very small pistols, using loads such as Hornady Critical Defense or Speer Gold Dot designed to expand at low velocity. The cartridge is low in energy compared with .380 ACP or 9mm, which is why modern micro-compact pistols have largely moved to those calibers.
How .25 ACP Prices Compare
The 30-day summary at the top of this page shows the observed price distribution for .25 ACP — the median, the quartiles, and how many retailers and listings stand behind them. The cartridge uses very little brass, lead, and powder, but it is made in far smaller volumes than mainstream handgun cartridges, so its cost per round does not scale with its size — compare its summary with the 9mm and .380 ACP pages to see the difference in current data. Practice FMJ and defensive JHP are listed together in the summary, with FMJ toward the lower end.
Pack sizes vary (25-, 50-, and larger counts), so compare listings by cost per round — the search button at the top of this page sorts current listings that way. A small box also makes shipping a large share of the delivered cost on single-box orders; see how to buy ammo online and the cheapest handgun calibers for how .25 ACP fits among handgun cartridges.
