In the end, it boils down to what feels best for you. If reliability is the main reason you would want a Glock, you have a ton of other options out there... most guns from major manufacturers are extremely reliable now (especially if you use the right ammo).
There's many ranges around DFW that have rental guns so you can try before you buy. I highly recommend that you do...
Personally, the feel of the XD series far surpasses the Glocks, but again, personal preference. I'm currently carrying a Beretta 96D in the winter and a small Beretta 948 in the summer (or in light clothing). The 96 is a little heavy though... lots of metal, no plastic
Once you know what you want, hit up a gun show and buy it!![]()
