Today’s lead article by our Senior Product Review Editor, Pat Cascio, is near and dear to my heart. This is because I and all of the adult members of my immediate family carry either Glock 30 or Glock 30S pistols regularly. I personally recommend the .45 ACP Glock 30 pistol for all but the most frail shooters.
But please heed this advice: Learn how to maintain it , buy a practical holster for it (I prefer the BladeTech Kydex holsters ), buy plenty of spare magazines for it (and half of those should be the larger Glock 21 magazines that hold 13 rounds), buy several magazine pouches  for it, and get the very best training that you can afford, at a top notch school like Gunsite . Your life, or the life of your loved ones may depend on it, sooner than you think! – JWR
