Glock fan, what is the best brand ammo for the Glock 23 40 s&w ?
I used car-bon 9mm 124 grain + p for smith wesson
You will be the one who decides what ammo is best for you. Through trial and error, I have found my preferences in ammo. There are several factors in determining what ammo is "best". Consider the following:
What the ammo is being used for (SD, plinking, competition, target shooting, etc.)
Performance in the individual firearm. (Certain cartridges work better than others though they may be the same caliber and bullet type)
Your individual shooting style and skill level. (Depending on your personal abilities, a lighter load may be better for you)
Budget (Many people subscribe to the school of thought that the most expensive ammo is the "best". I personally feel that you will need to spend some decent money for quality ammo, though it doesn't need to be the most expensive.)
My suggestion would be to purchase various loads and see what works best for you for the intended purposes. A very important, and often overlooked step in the ammo selection process is test firing. If you carry a firearm for SD, you should fire a box or two of your SD ammo on a regular basis. This ensures that the rounds function properly in your firearm and builds confidence in the round.
