Carry guns didn’t evolve in a straight line. Every few years, a handgun comes along that shifts what people consider practical, comfortable, or even necessary for everyday carry. Some models set new expectations for capacity. Others changed how people think about concealment, shootability, or reliability in compact sizes.
When you look at today’s market, you can trace a lot of trends back to a handful of pistols that pushed the whole category forward. These handguns didn’t just sell well—they changed how people think about carrying a gun in the first place.
Glock 26
When the Glock 26 arrived, it proved you could carry a double-stack 9mm without sacrificing concealment. Its grip length, thickness, and overall footprint set a new standard for what a compact defensive pistol could be. Shooters appreciated that it still handled like a larger Glock, which built confidence for people who didn’t want to switch platforms between home and carry roles. The 26 also helped normalize high-capacity subcompacts, something the market hadn’t fully embraced before. It showed that a small gun didn’t have to feel compromised or underpowered.
Smith & Wesson Shield
The original Shield changed everything for single-stack carry pistols. It was thin, easy to shoot, and came in at a price point that made concealed carry far more accessible. The Shield stayed controllable despite its slim frame, which gave newer shooters a gun they felt comfortable training with. It also helped large numbers of people transition from larger handguns to something they were willing to carry daily. Its reliability and straightforward ergonomics created a blueprint that the entire market followed for years afterward.
Ruger LCP
The Ruger LCP redefined pocket carry for modern shooters. Before it showed up, truly lightweight .380 pistols were limited and often unreliable. The LCP proved that a sub-10-ounce gun could be dependable and easy to stash in nearly any clothing style. It made deep concealment practical for people who wouldn’t have carried otherwise. The pistol’s success opened the door for a whole class of micro .380s that followed its basic footprint. Whether you love it or not, the LCP influenced the carry landscape more than most guns its size.
SIG Sauer P365
The P365 reshaped the carry world by showing that a gun this small could still hold double-digit rounds. The micro-compact, high-capacity format became the new standard almost overnight. Shooters realized they no longer had to choose between comfort and capacity, which changed buying habits across the entire industry. Despite its size, the P365 stayed accurate and manageable under recoil, something many competitors still struggle to match. Carry guns before the P365 and after it feel like two different eras.
Walther PPS M1
The PPS M1 gave shooters a slim, reliable, striker-fired pistol before the market became crowded with similar designs. Its paddle-style release and overall ergonomics made it stand out, especially for people who wanted something more refined than other early single-stacks. The PPS was accurate, consistent, and comfortable to carry, which helped push the idea that thin guns didn’t have to be snappy or difficult to run. It quietly shaped expectations for what a quality slim pistol should feel like.
Kahr PM9
The PM9 proved that a small 9mm could be smooth, reliable, and easy to conceal long before the micro-compact era. Its trigger system and slim frame made it a favorite for people who wanted something smaller than a compact Glock but more capable than a pocket .380. Kahr’s machining and steel-frame roots gave the PM9 a level of refinement that surprised many shooters. For years, it was the benchmark for deep concealment in a 9mm format, influencing dozens of designs that followed.
Glock 19
The Glock 19 set the standard for what many people consider the ideal carry size. It offered enough grip to shoot well, enough barrel length for solid performance, and a footprint small enough for daily carry. Its reliability and aftermarket support built a reputation that reshaped training programs across the country. You see so many “G19-sized” pistols today because this format works for a wide range of shooters. The 19 didn’t just enter the carry world—it helped define it.
SIG Sauer P938
The P938 showed that a metal-framed, single-action micro 9mm could be both reliable and practical. It gave shooters a familiar 1911-style manual of arms in a far smaller package. Its trigger and ergonomics made the gun shoot better than its size suggests, which helped many people transition from .380 pocket pistols to something with more punch. The P938 helped bring single-action micro-guns into mainstream carry conversations in a way few pistols had before.
Springfield XD-S 9mm
The XD-S entered the market when shooters wanted slimmer guns but still demanded controllability. It delivered a strong combination of grip texture, manageable recoil, and affordability. The XD-S helped normalize the idea that single-stacks should feel solid and shootable, not like stripped-down versions of larger pistols. Its reliability helped it gain popularity with concealed carriers who wanted a straightforward, effective option that didn’t require aftermarket improvements.
HK P2000SK
The P2000SK introduced a level of refinement and durability to the subcompact DA/SA world that previously lived mostly in full-size pistols. Shooters appreciated its controllable recoil, modular backstraps, and long-term reliability. It became a favorite for people who wanted a hammer-fired carry gun with real service-grade performance. The SK proved that subcompacts didn’t have to feel compromised or cheapened versions of their larger counterparts.
