I just turned 21 in June, and my dad gave me his first service pistol, which was a Gen1 Glock 22. I have already shot this gun a lot, and you can tell this gun has been shot a lot prior to my owning it, but the gun still shoots like it is new. I have thought about getting it blued, but I have decided against it because of the sentimental value of the gun (the serial number is his old badge number). I had struggled with which gun to buy for myself and my every day carry. Now that I have received my CCW, I had been going back and forth between a Glock 19 (or 42) and M&P shield. Last weekend, my fiance's dad bought me a M&P shield with a green crimson trace laser, and I have fallen in love with the gun, especially since it is smaller and summer is coming up. But, my question is, should I still buy the Glock 19, even though it is larger and could be great to carry in the winter, or should I just stick with the Shield for a while?
