Hey fellow Talkers, I've been thinking lately about becoming a Glock owner. Yes, I know that I was a semi auto guy......then a wheel gun only man.........then a combination. Ah, lets face it. I should be a woman as much as I change my mind. But hey, this is America, and I'm free to do so (unless Obama decides other wise). Well , here is where we stand. I have been looking into the 23 mostly because of the 40 cal. The other standpoints that are a persuasion in this is that it's a little more concealable than the 22 and isn't too tiny like the 27. So why am I posting here? Well, there are a few questions I have and would also like some opinions. For starters, I'm pretty sure that with the 40, all I have to do is swap the barrel and I've got a 357sig......right? 40 might not, but I'm sure that 357 is plenty to take down hog as a back up in the woods to my rifle. No I am not going hog hunting with a Glock, but I am NOT going hog huinting without a sidearm that will take one down at <40yrds. And please, let me know if I'm wrong here. No, this will not only be a hunting sidearm. It will serve as night stander, edc cc, hd, sd, and fun in the back yard. So it is going to be as close to an all around handgun as possible. Another is the gen.3 vs. gen.4 thing. Other than the grip texture and mag release, I don't recognize any other external differences. Internally there is a double recoil spring. Have I missed anything? Also, how much does the double spring help? Yes, I know. I'm a Glock rookie. But I don't come lightly with dumping $500 on another mistake. No, I didn't say it was a mistake to buy a Glock. Don't go all Hitler on me. All I'm saying is I want to be sure about my upcoming purchase. Now, am I positive that I want a Glock? or the 23? No. But other than a revolver, I can't think of another pistol that would fill the roll so well. Yes there are others, but not with the rep of Glock, right? So, what I need is opinions, input, answers, insight, and anything else that you think I might need to know. This includes any mistakes that I may be about to make and any wrongs that I may have thrown out there. And don't forget to mention anything that I could have not thought about. Thank you for your thoughts.
