This was sort of my point much earlier on. GLOCK makes 10mm guns, and I think Kimber makes/made one. Other than that, they are limited-production special order items from custom shops.
Look, in current production 9mm guns, I can get a 6" longslide auto, a 5" racegun, a duty sized pistol, a compact duty pistol, a subcompact, a mini-pocket sized gun, a derringer, a revolver, a carbine rifle, a submachine gun, etc.
If I go with 10mm I can get the GLOCK 20 or the GLOCK 29. I know the actual CARTRIDGE may be more versatile, but overall the 10mm is VERY limited. I wish it were more common, but then again, I also wish I could get revolvers in 10mm-rimmed, and carbines in 10mm, etc.
:banghead:
There are over 20 current production 10mm pistols, from compact polymer guns to 6" hunting pistols to competition guns and even the S&W 610 revolver. Prices range from $300 to as much as you want to spend on a custom.
And don't forget the Mechtec and Oly-arms K-10 in the carbine department.
Yeah, you're right. They don't have virtually the same case capacities and operating pressures or anything. Oh, wait..........yes they do
10mm: 24.0 grs. H2O, 37,500 PSI
.357 Magnum: 27.0 grs. H2O, 35,000 PSI
Anyone who's played with both knows darn well they're ballistic twins. Out of pressure barrels, max loads for either mirror each other. When comparing a 5" barreled auto to a 4" revolver (making for a 5.7" chamber & barrel), the 10mm will come out on top, because there is no cylinder gap. That's where the advantage lies. To make .357 mag loads hit the 770 ft/lbs my 10mm loads will in a G-20, I have to go to my behemoth 6" 686.
S&W 586 4", 158 gr. JHP, 13.0 grs. blue dot: 1,440 FPS & 727 ft/lbs
S&W 686 6", 158 gr. JHP, 13.0 grs. blue dot: 1,495 FPS & 783 ft/lbs
Glock 20 4.6", 180 gr. Golden Sabre, 10.8 grs. IMR-800x: 1,390 FPS & 772 ft/lbs
Witness Limited 5.25", 180 gr. Golden Sabre, 10.8 grs. IMR-800x: 1,430 FPS & 817 ft/lbs
Both the .357 Mag and 10mm loads listed here are slightly (0.5 gr.) over max published data.
Furthermore, while ballistic twins they may be, the advantage of the 10mm offering that power in a lighter weight, more compact handgun holding 2-1/2 times as many round is rather obvious.
I love my .357's, but I'm not diluded about what they are or aren't, and if it's my bottom on the line, I'll grab a 10mm every time.
