That being said sub-compact autos, slim-line autos, mouseguns, and J-frame Smith revolvers all have their zealot followers.
Some specific models that will have a large following include but are not limited to:
Glock 26/27, Kahr PM9/PM40, and other subcompact polymer pistols.
Glock 19/23, Springfield XD compact, and other compact polymer pistols.
Compact 1911s from reputable companies such as Kimber, Springfield, etc.
Smith J-frames such as the Model 36, Model 442, Model 340.
Smith K-frames such as the Model 13 & 65 with 3-inch barrel.
Smith X-frames such as the Model 500 (this was to see if you're paying attention)
Kel-Tec P3AT, Ruger LCP, Seecamp, Beretta Jetfire, and other Mouseguns.
