Are there cartridges that just
don't appeal to you?
Absolutely. Quite a few. There are no cartridges that I "hate". There are some I wonder why on earth they exist at all, but none I hate.
What I do hate is some cartridge/caliber/specific gun fanatic trying to convince me that I don't know what I know, and that his views are the only valid ones, and apply to everyone in the world equally until the end of time.
Those folks, I find tedious.
Having begun my learning curve in handgunning back in the day when factory auto pistol ammo came in two types, duty and match, and the bullets were either FMJ RN or FMJ SWC, I was never a fan of the 9mm Luger. Back then, with the exception of the 13rnd Browning Hi Power, anything the 9mm could do, the .38 Super could do better. Things have really changed.
I have several 9mms in my collection now, but none of them is a gun I would choose for personal defense or street carry today. P.08, P.38, and a Bolo Mauser C96 aren't thought of as good street/duty guns today. No plastic, for one thing!
I have no interest in the various .40s or .41s, either. Nor the .357 Sig. Nor am I interested in calibers above .45. The .475s & 50s don't interest me, primarily as I do not wish to tool up for that caliber, and have even less use for one of them than I do for .44 & .45 magnums, of which I have several.
No real interest in a .380 either, other than if I find a historical pistol in 9mm Kurz for a good price (hoping for that WAa marked ppk for less than the cost of a used car...)
Although recently I found myself with a 1919 Savage and a WWII Mauser HSc, .32ACPs. So now I am going to load some ammo and check out the real capabilites of the round, first hand. I may even look into the .25 auto, after decades of derision.
The East Bloc handgun rounds do not interest me much, either.
I'm sure this overlooks something, but there are more things I AM interested in than not. My world does not revolve around duty/defense class handguns or the most power and firepower in the most concealable package school.
Nor am I all about something because it is cheaper and or more available than something else. I don't pick my guns because of what's cheapest on the shelf or what I can get "worldwide". I don't travel worldwide, so that is of absolutely no concern to me. But for some, I guess its a important thing.
My favorite 9mm pistol for shooting pleasure, is
extremely accurate and feeds absolutely everything, 100% of the time! And it has a 6" barrel and a trigger like glass.
Might be the best 9mm, but if not, its a real Contender!
