Hello all For those of you that carry a glock 45. I am talking about the glock 21 or the glock 30 only. Which one do you carry and why did you pick it. The size difference really isn't much, the weight difference loaded is only 6 or 7 oz's, the width is pretty much the same. As far as the accuracy they are for me any way the same they both have hardly any recoil for a 45 acp. The most noticeable difference would be the 10 rd mag compared to the 13 rd mag. All things between the two are pretty close so why did you choose the one you carry? Wanna kill these ads? We can help!
