I own two glocks. I have the full size 21 in 45 acp. I also have a baby glock 26 in 9mm. I love them. I have put well over 50,000 rounds throught the 21 without a single problem. I have put 10,000 rounds through the 26, with no problems. They are wonderfully accurate and reliable. I also own two XD's. One is a four inch 357 sig, and the other is a five inch 40 S&W. They are also great guns. Glock or Springfield will both suit you fine. Just my $.02
