If you plan on getting your CCW (concealed weapons permit) I would highly recommend that your first firearm be a pistol. I would also recommend, if you are purchasing this weapon for self-defense to be a revolver because semi-autos often jam. If it is not for self-defense I would recommend one of two guns. If you are looking for a cheaper firearms look for a sig-sauer 9mm. DO NOT BUY A GLOCK. GLOCKS are terrible. The recoil they sustain is absolutely horrendous. It is like putting a .44 caliber hollow point in a .22. Anyway, if you want to purchase a more expensive firearm I would highly recommend a Model 1911 .45. Kimber makes a very nice one known as a Kimber Goldmatch .45. They are difficult to come by but they are beautiful (I have a silver wood gripped one) dead accurate, any have very low recoil for a .45 caliber firearm. I own many guns take it from me...
First, this person has NO IDEA what he/she is talking about here. None.
Second, I own dozens of guns and like all brands, types and calibers. There is NO PERFECT Pistol/handgun and if there is, I haven't seen it or fired it. But, there are many excellent handguns on the market some for $500 and others for over a $1,000.
Third, Glocks are OUTSTANDING guns and in 9mm are extremely low recoil. Glock's 4th generation guns do not have "horrendous recoil" in .40 or .45 caliber either. But, the 9mm is a gentle gun which is one of the finest shooting firearms on the market for under $550.
Glocks are reliable and rarely, if ever malfunction, provided the owner is using good ammo (124 grain 9mm is preferred for the 4th generation) and properly lubricated the weapon.
Despite my comments about Glocks I still prefer a HK, CZ, Sig or Beretta 92 over a Glock 19.
Fourth, I like 1911 style weapons. They are beautiful show guns and very accurate. Kimbers can easily run $2,000 and custom 1911s over $3K. But, these guns are prone to more jams than the modern semi-auto, are only available in single action and are difficult to clean compared to a Glock,HK, Sig, CZ, etc. I do not recommend a 1911 as your first gun but rather as your last gun in a collection (not that there ever is a last gun until death).
Finally, a 9mm is a light recoil round compared to a .45. This makes shooting the round and hitting the target much more likely for the average person. A 9mm round is an excellent self-defense round in hollow point and I recommend that caliber if you want to own a semi-auto.
With a revolver stick with a .357 that shoots the old-fashioned .38 round as that will be the easiest gun to maintain in a state of readiness for non gun types.
The more you shoot a modern .357 the more you will grow to love that wheel gun.
