Back when I turned 21, I bought my first handgun. The first step was to decide on caliber. It was going to be a .40 or .45, 9mm was too small and I was a man's man. After talking to many people and many nights of research online, I decided on the .40 for magazine capacity and it was, to me it was the ultimate caliber without a doubt. Then I went to my lgs and handled a glock, xd, and the new px4 (new at the time). The px4 fit me like a glove. It was like King Arthur wielding Excalibur for the first time. It also came with adjustable back straps and the added benefit of a rotating barrel to absorb recoil and claims of excellent accuracy. The pistol has held up over the years to a few thousand rounds and is ridiculously accurate. It's always been reliable too. Let's fast forward to today. From the day I bought my px4, I have been a die hard .40 s&w fan. I preach .40 to everyone and had no use for 45 and 9mm. .40 is that happy medium. The only other caliber I was considering was a 10mm but that was a want and not a need at the moment. In the last several months I was wanting something new and my life and needs have changed. In the last few years I have been wanting a Glock. They are nearly bullet proof, accurate, reliable, they have the best magazines IMHO for quality and capacity, and Glocks are just down right awesome. I've handled a few different models that family and friends own (g17, g21 and g21sf, g20c, and a g22). Never a compact always full size but I still love them, except for in the larger calibers I like the grip on the sf models. Anyway I've been wanting a compact pistol for my ccw and my wife's home defense weapon. The px4 is too big for my wife's hands and not practical for concealment. So the next pistol I was buying was going to be a compact Glock and of course a .40. The Glock 23 gen 4 was coming home first chance I got to go to the lgs. One Saturday my buddy and I went to the range. I was 100% sure I was buying a Glock 23 gen 4 so that day I rented one. I shot great for the first time with it and liked it. Then my buddy leaned over and said try my gen 3 g19. This is when I had the epiphany. The 19 was far more accurate, follow up shots were extremely faster, it still fit my hand the same, the mag holds two additional shots, and for my intended purposes for it it was literally perfect. My wife could handle the g19 far easier than the g23. I really like the g23 but the way it recoils slows you down on follow up shots. On a side note, the recoil of a .40 is nothing to complain about as far as intensity. It's just funky in how it pops up and twists so it takes longer to realign sights for follow up shots. After a lot of research, and realizing that I can buy 9mm ammo equivalent to that of .40 and it's cheaper, higher 9mm availability, and have two extra shots in a ccw, I bought the Glock 19 gen 4 with the fde frame. I also had the lgs add Trijicon hd night sights. The gun fits me well and fits the wife even better. I was never a huge fan of the gen 3 grip but the gen 4 grip is the bees knees. I'm loving the Glock world too. You can customize anything on the gun, accessories are everywhere and easy to order, and you can go to bed at night confident that it will fires hen needed. When I bought the px4 there were basically no accessories anywhere and the few on beretta's site I could never find. One thing the Glock has over the px4 is no thumb safety. The safety on the px4 is terrible. I like the decocker functionality but hate that you have to reach up so damn high to engage/disengage. Well I guess the moral to the story is to get out and shoot different makes, models, and various calibers. You might have needs and wants today that are far different from the future. Don't believe everything you read online either. I hate the hundreds of caliber war threads. This post is not to persuade anyone just to tell my story. I think I'm still in shock that I own and love a 9mm. At the end if the day I feel that I have the right tools to keep my family and myself safe. Hopefully I'll use all of my handguns for range time and hunting purposes and never for defense.
