Hello, So first and foremost, I am a firearms noob. I shot a few black powder rifles as child because my father was into them but other than that, no prior experince. That said, my wife and I both have our carry permits. My father in law is an avid hunter and gave her a .38 snub revolver for ccw. I mentioned in passing that I should obtain a gun as well and put my permit to use. Well he was very nice because a few days later he offered me one of his guns. I am not sure of the model but it was a tiny little semi auto. I could easly palm the whole thing. I 380 of some sort if I recall. I politely declined. So I started researching hand guns and almost instantly fell in love with the glock. Most people seem to the thing they are ugly....I think they look like what a pistol should. So I asked my father in law to come with me to a gun store and help my pick one out. He did so and after handling about every glock option, the 21 was for me. It just fit my hand perfect. I was aware that the 9mm was cheaper to shoot and the subcompacts are eaiser to carry but none of them felt right but the 21. I was ready to make a purchase right there but he said to wait, that he had just about every caliber there is (none glock, he prefers 9mm sigs) and then make a purchase. I was sad but I listened. I was honestly worried that the recoil on a 45 would be to much for me (I am not a big guy) but like I said the fatter grip was a perfect fit. So I went to his house and shot a 9mm auto, .38 revolver, .45 SW revolver and 45 auto. After shotting the 45 auto, he said you still like that 45? I said oh yeah, i was afraid of the recoil but turns out, it's not a problem. He said ok, load up a full clip and have at it again. At this point I was doing well to get one round out of a clip on the paper (remember I am a total noob). So I refilled a mag and gave it another go. After I was done I turned around and he said you still like it? I said yup. he said ok try that one. I looked down and there was a brand new glock 21 in it's case. I said that's a glock...he said yup. I said you don't like glocks...he said nope. I said then why do you own one? He said I don't. I said then who's is it? He said yours and tossed me a box of .45 acp....load it up. Turns out he went half in one on with my wife and bought it for me! He also provided a mags worth of hydra-shok for ccw. Now is that awesome or what???? Now I dunno if it was my happiness or that perfect hand fit but the first three rounds out of my glock 21 were on the paper, it was the best I did all day and there are now three loves in my life my wife, my glock and .45 ACP. That said, the 21 is not a small gun, any advice on a ccw holster other than open carry and IWB? Second question, I have not shot it since a few days ago with that first box of ammo, any suggestions on what to get to clean it because I am guessing it needs cleaned. Thanks for listening!
