In addition to my own research and what my students bring into the Concealed Handgun Carry class every week, this guide was reviewed by Tom Givens of Rangemaster, whose opinion appears below. The method line at the end of the article says exactly how this guide was built.

Quick answer

There is no official standard, but in practice a micro-compact is about 5.8–6.1″ long and 4–4.6″ tall with 10–13 rounds of 9mm (SIG P365, Hellcat); a subcompact is a short-gripped gun around 6.25–6.7″ long (Glock 26, CZ P-10 S, Glock 43X); and a compact is about 6.6–7.5″ long and 4.8–5.4″ tall with 15–17 rounds (Glock 19, P365-XMACRO).

Manufacturers use these labels loosely — Glock calls the Glock 48 a subcompact even though it has a Glock 19-length slide — so it helps to look at real dimensions instead of names. The ranges below come from the manufacturer specs of the 30 carry guns we track.

Expert verdicts

In one line: Compact vs subcompact vs micro-compact pistols differ mainly in grip length, height and capacity; carry the largest size that disappears under your everyday clothes.

Chris Raper — reviewed: Suggested draft — rewrite in your own words Manufacturers use these size names loosely, so look at the dimensions instead of the label. A micro-compact is roughly six inches long with ten to thirteen rounds of 9mm, a subcompact has a short grip, and a compact is longer and taller with fifteen to seventeen rounds. The class you should carry is the largest one that disappears under your normal clothes. Students who buy the smallest gun first often end up shooting it badly.

Tom Givens, Rangemaster — opinion: Suggested draft — rewrite in your own words Size labels matter less than one practical question: can you carry this gun every day and still shoot it well at speed? The compact is easier to shoot and holds more, but it is harder to hide. The micro-compact hides easily but demands more of your technique. There is no wrong answer if the gun is with you and you have trained with it. The wrong answer is a pistol too big to carry consistently, or too small to shoot with confidence. Rent or borrow each size if you can, shoot them on a timer, and pick the largest class you will actually wear in your normal clothes on an ordinary day.

Ranges from manufacturer specifications of the guns we track (October 2026). Individual models fall outside these ranges.

Micro-compact

Micro-compacts are the modern default for everyday carry: thin (about 1–1.1″), light (around 18 oz) and holding 10–13 rounds. Their short grips are what make them easy to hide — and what makes them snappier and harder to shoot fast. Best for IWB and appendix carry in light clothing. See the best micro-compact 9mm pistols.

Subcompact

“Subcompact” covers two different kinds of gun: short double-stacks like the Glock 26 and CZ P-10 S (thicker, around 1.3″, with a stubby grip) and slim guns like the Glock 43X (thin with a longer grip). They usually shoot a little softer than micro-compacts but are slightly bigger in one dimension or another.

Compact

Compacts like the Glock 19 are the all-rounders: big enough for a full grip, 15+ rounds and easy accuracy, small enough to carry with the right holster, belt and clothing. Newer “crossover” guns such as the P365-XMACRO and Hellcat Pro combine compact grips and capacity with micro-compact width.

Which size should you carry?

Light clothing, small frame, or deep concealment: micro-compact (or pocket gun for pockets).
Want the easiest-shooting gun you can hide: compact or crossover (XMACRO, Hellcat Pro, Glock 48).
One gun for carry, home and range: compact.
Struggle with recoil: go bigger and heavier, not smaller.

Specific picks for each class are in our main best concealed carry guns of 2026 guide and the smallest 9mm pistols ranking.

FAQ

What is the difference between compact and subcompact?

A compact (like the Glock 19) has a longer grip and slide and typically holds 15+ rounds; a subcompact (like the Glock 26) shortens the grip — and often the slide — for concealment, typically holding 10–12 rounds.

Is a micro-compact smaller than a subcompact?

Usually, yes. Micro-compacts like the SIG P365 are generally thinner and lighter than traditional double-stack subcompacts like the Glock 26, while holding similar capacity.

Is a compact pistol good for concealed carry?

Yes, with a good holster, gun belt and suitable clothing. Compacts are easier to shoot well than smaller guns, which is why many experienced carriers choose them.
