I've always though we needed a smaller revolver as well...
BTW, my J frame is an Air Weight 6 shot 32 H&R magnum... & yep... it doesn't fit in my jeans front pocket, even after I switched to "relaxed fit"
there are the older guns like pictured above...
my favorite "small guns" are single action top break S&W's the 2 I have pictured here were chopped to snubbies long before I bought them... that just means I was able to buy them very reasonably, because they aren't correct for the S&W collectors...
this little 32 S&W, is how I bought it, sans the NOS 60's Gil Scotti laminate grips I added ( also added the nickel S&W medallions to those grips ) I handload 32 S&W, & have more tame range ammo, & a few "hotter" self defense loads that I try not to put too many through... without the trigger guard, & using the spur trigger, this gun is literally 1/2 the size over all, of a J frame
this little 38 S&W is also how it looked when I bought it, ( it appears to have been carried a lot, & not shot much, as it's really ugly, but in great mechanical condition ) I bought this one dirt cheap, it's bigger than it's little brother pictured above, but still quite a bit smaller than a J frame... I also reload for this cartridge... in fact, I used this gun the last time I re-newed my CCW... instructor was interested, since it was the 1st time someone had used an antique gun, to range qualify... I still was able to out shoot about 1/2 the class of newbies, with their compact 9's... I found a set of original mother of pearl S&W grips for this gun, with brass S&W medaliions, & right now, this gun is at the "spa", getting whats left of the original nickel stripped, & a master re-blue, gold plated trigger & hammer, & since these guns don't have the cartridge designation on them, in easy to read script, gold filled "38 S&W" engraved on the side cover... BTW, the grips pictured are not correct for the gun ( they are either I or J frame grips ) & seem much bigger than the MOP grips I have
I would love to see something modern like either of these guns, maybe in 32 ACP, & 380 ACP, just to keep them short & light...
If I'm happy with the work on the 38 pictured above, the 32 will go in for the same treatment, but with nickel plated hammer & trigger, & nickel filled "32 S&W" on it's side cover...
