That Sir is incorrect, both Glock and Sig (as well as others) offer semi's in the .357 caliber. The Glock models are the 32 (Compact) or the 31 (Full Size). Or the Sig 226 or 229 both you can get in the .357. BTW if you want a DE go for the real deal .50 AE, it has waaaaaayyyyy more stopping power. For my money I would go Glock. Try to stay away from the 10mm, .45 GAP,. 357 Sig, 50 AE as these caliber or ammo are sometime (More than not) hard to get or expensive (especially when you goto the range for practice)...... Also stay away from the cheap brands like Star, Jennings, Hi-Point, Larson, ect most of these FA's are of inferior construction and are prone to FTF. Especially if you live in a FA friendly state goto the range and rent some FA's to see what feels right in your hand.
