When I bought my first Glock the only model available was the 17. I guess that gun made an impression, because from there on I have alway gone with the 17 sized frame. I generally hunt, camp, and explore in the deserts and the mountains, so I saw a full size as an advantage. I carried my 34 for years and before that my original 17. A while back I bought a Gen 3 Glock 19 on sale and it just sort of languished in the safe. I have pretty big hands and it just never fit right. Then I picked up an Agency Arms Glock 30 and it fit like a glove. That got me thinking about the 19 in the safe and I compared the two guns. I realized that I needed to remove the finger groves and slightly undercut the trigger guard. After just a few minutes of work, the Glock 19 felt like a different gun. When I took the gun shooting I found it shot almost same/same with my 17 but was just a bit easier to carry around. So I added a light, got a Tenicor ARX LUX (Both work equally well on my G45) and ended up loving the package. I just got back from spending a few days in the desert and carried it the whole time. It is easy to conceal under a t-shirt, doesn't bother me or my seat when in the truck, and is easy to draw and shoot from the holster. All in all it is an excellent field pistol that works just as well as a CCW in town. While I realize I am hardly the first person to figure this out, I am surprised it took me so long. I love shooting my Glocks but never gave this frame size a good go. Besides being a long and somewhat rambling post, I hope it is a reminder to go through the safe from time to time and reevaluate those soiled doves in the back corners of the safe. You never know what might come of it.
