My wife and I are new shooters who recently purchased our first two pistols - a Glock 19 and 26, both new Gen 4's. We have read different opinions concerning the amount of ammo to have on hand but we have not seen recommendations on what percentage of that ammo should be defensive and what percentage range ammo. We presently have about 1600 rounds of range ammo with the intention to purchase a thousand rounds every time we get down between 800-1000. We have a very small supply of defense ammo and will be looking to make a purchase soon. We will probably shoot one magazine of defensive ammo each time we hit the range just to work it in and keep it fresh. Any input on how much defense ammunition is reasonable given it will not be shot often? We would likely be shooting say ... 100 defensive rounds per year. We were thinking 500 defensive rounds on hand at all times. That would give us a ratio of 3 range rounds on hand for every 1 defensive round. Thoughts?
