I shoot once a month at an indoor range that has a 30' max length - handguns only. My other sessions are at various ranges including one I have set up at the farm. One of the counter guys (it doubles as a gun store) is also a .32 aficionado and shoots/owns .32's. It's also one of the few indoor ranges in a 2 state area that you can just walk in, plunk down range fees, and shoot. So it seems to draw "all kinds" especially in the Winter and now that Illinois has CCL.
I have seen several Tomcats and Kel Tec .32's go out the door and they usually have a couple .32 pistols under the glass (and stock .32 for range ammo) so I suspect at least some of the other .32 shooters purchased the guns where they are shooting them. There is a gun store right across the river in Iowa that always has a Tomcat or other .32 pistol under the glass and these move for them on a regular basis 'cause I asked if they sell 'em or if they just "sit there". Apparently there are more .32's and .380's in the "general population" than those of us who frequent gun boards believe. At the local indoor range there are usually 10 - 20 other shooters actively shooting when I am there...who knows who's shooting 9mm and who's shooting .380 or .32 or .40 or .45? Relatively they all sound the same behind hearing protection and the brass all mingles on the floor. I'm still surprised to find .32 mingled with my brass when I'm shooting 9mm and sweep up but almost always it is a mix of .45, 9mm, .380, .40 etc.
I am personally guilty of recruiting .32 shooters myself having worked very hard for almost 2 years to help my recoil sensitive Wife select an alternative pistol for CCL after she had to give up her Colt Officers .45 - it just beats on her and literally hurts her now that she is mid 50ish instead of mid 20ish. She shot a lot of .32 in our Colts and until she settled on her G42 it was her main squeeze. Many other women or less experienced shooters were "converted" at the range we shoot at watching her progress from "incompetent and compromised" to *hammering* targets with .32 and .380 pistols and asked her for direction and help because of similar issues.
My Wife is a cute and perky, kind and helpful and easily approached. People having "problems" at the range ask her questions about what she's shooting and many women who have had .45's and powerful pocket rocket pistols forced upon them as "the minimum viable alternative for SD" by trainers and significant others see her doing what they cannot and will never do with guns they have been "forced" to shoot and start asking her "How come you shoot so well and I suck?" and it goes from there.
And she starts them on .32 pistols and brings them up and into our local group which tries to help folks find better choices and manageable CCL pieces using other members guns as loaners. Some of them progress onto 9mm and even .40 and .45 pistols if they get comfortable. Many stay at .32 and .380 when they get comfortable and accurate as I'm a true believer in shooting the biggest caliber you can handle in rapid fire with fast, accurate follow ups and, truthfully, most casual shooters/normal shooters we encounter reach their practical limit in controlling recoil with small, concealable .380's. Many are converts from subcompact 9mm's that they just never carried because, frankly, they cannot shoot them as well as a comparable sized .380 and the 9mm and .40 caliber guns beat them senseless and physically hurt them/reduce training time.
So we have unfairly seeded the local pistol gene pool with .32 aficionados as well.
I personally had not much use for .380 until the G42 came out and my Wife gravitated to it due to it's soft shooting characteristics even with some down right hot .380 which exceeds my hot .32 hand loads and fills the "biggest/most powerful round you can handle in rapid fire with fast, accurate follow ups" rule. So we now have .380 in the house as well as .32 for me to re load.
