Maybe because the 9mm requires moonclips and has a narrower range of bullet/weight/velocity options as compared to a .38/.357?
You might want to try telling that to S&W and the many, many Model 547 owners. Oh wait, they don't use moonclips! Reading is fundamental. Therein you'd likely find that I never once compared the 9mm to the .357, but rather the 9mm to the .38, a comparison which drastically favors the 9mm.
Can't remember the last time I loaded a revolver magazine for a .38/.357. Still remember loading moonclips for 9mm though.
Where exactly did I say that revolvers use magazines? The point is that if you want to load quickly, you'll be loading a speedloading device or a magazine no matter which choice you make. I don't remember ever loading a moonclip; the 547 doesn't use em. If someone is going to complain about loading moonclips, they're the type to complain about loading magazines for a semi-auto 9mm. It must be dealt with or discarded as an argument.
Why would anyone want to give up the option of wadcutters? You don't like the option of cheap lead plinking ammo? Maybe that lets you justify jacketed 9mm prices?
When comparing .38 to 9mm, the only benefit of wadcutters is "Hey! Look at those clean holes!" The notion of "cheap wadcutters" in .38 or .357 is a myth, unless you are casting your own lead bullets for reloading. Factory 9mm FMJ has been cheaper than factory .38s for over two decades now.
Until the Sandy Hook shortage started, there were always more options in .38/.357 around here than in 9mm. Both been pretty equal since then, nothing at all of either one.
Again, my arguments are based on the concept that if a 9mm revolver is pointless, than a .38SPL revolver has
even less utility. The 9mm can't be fairly compared to the .357MAG b/c the .357 will almost always outperform it. Comparing 9mm to .38s, the 9mm has the edge across the spectrum when it comes to cost and performance.
On what trailhead, or should I say planet? Never saw factory lead 9mm anywhere, but cheap factory lead .38 (wadcutters) was available all over the place.
I've never found factory lead 9mm anywhere either; there's no need for it when ammo is 12-20 cents/round. On the other hand I haven't seen any factory .38SPL in that price range in the past 15-20 years. We're talking FACTORY loads, right, not Bubba's "remanufactured" loads...
