I'm thinking my next pistol should be a full-size "Tactical" (whatever that really means) semi-auto with as much capacity as can be crammed into the grip, which can definitely be as fat as the fattest Glock 'cause the Good Lord blessed me with big, skinny hands. When I say "full capacity" I'm thinking at least 15 rounds or more. I realize that leaves .45 ACP out of the running with only 13 rounds max capacity of any semi-auto I know about, but I decided to make an exception for that caliber and leave it in. At present, I have two subcompacts, S&W 9mm and G29 10mm, one compact 357 Sig Steyr and one 9mm Kel-Tec PF-9 pocket pistol, so I'm thinking a full-size SHTF pistol is the next hole to fill in my personal defense outfit. Here's the caliber candidates first, with the hottest rounds I could find on any ballistics table or website: Grains/Type/Mfg./FPS Muzzle/Ft.lbs. Muzzle 357 Sig: 125/JHP/Gold Dot DoubleTap/1450/584 ft. lbs. 9mm: 124/JHP/Gold Dot DoubleTap/1301/473 ft. lbs. 10mm: 135/Nosler JHP/DoubleTap/1600/767 ft. lbs. .45 ACP 165/JHP+P/Cor Bon/1250/573 ft. lbs .38 Super 125/JHP/Winchester/1240/427 ft. lbs. 9x23 124/JHP/Winchester/1460/587 ft. lbs. So to rate the calibers from baddest to least bad (but still pretty bad), 10mm is 1st, 357 Sig is 2nd, .38 Super and 9x23 are combined for 3rd place, .45 ACP is 4th (with the 13+1 handicap) and 9mm is 5th. I combined .38 Super and 9x23 because full-size EAA pistols will hold 18 rounds of each and will shoot each interchangeably without any modification. It's a good twofer because .38 Super is cheaper ammo but that 9x23 Winchester round outperforms everything else on my chart except 10mm, plus ammo is cheaper than 10. So now, let me consider pistols. The Glock 20 and the EAA Witness and Elite Match are, so far as I know, the only 15-shot 10mm pistols available. The EAA Witness and Elite Match are also available in .38 Super/9x23 with a full capacity of 18+1, which in my mind gives it a leg up over the 10mm choices. Choices in 357 Sig are limited to what I can afford, probably a Glock 31. Wish I could afford a genuine Sig. Sigh! Choices in .45 ACP are a bit better: Springfield XD, Glock, S&W M&P, all 13+1 and roughly same price range. Choices in 9mm are even wider, including the above and others, but as noted, 9mm is my last choice. What thinkest thou, fellow Steyroids?
