    how many test rounds to verify your new gun's defensive ammo

    I don't want to be $hooting thi$ for practice, but I know that you need to run a number of rounds through to be sure it agrees with your firearm.

    What would be the minimum of the expensive HP rounds you would shoot to verify before carrying for defensive purposes?

    Gun in subject is a Glock 19.

    100 to 200 with zero failures is what I do. Same is recommended in my classes. I'd rather see a failure in expensive ammo on paper instead of real world need.

    Absolute minimum 100, I'd be happier with 200, with no glitches.

    It would depend on the gun and the ammo you are shooting.

    For the G19, I guess a hundred or two would be fine, but if it is a common ammo that you know lots of people have shot through their G19's you might not need to shoot even that many.

    If it is some off the wall ammo that very few people use, you might want more than 1 to 2 hundred rounds down range.
    Just remember that shot placement is much more important with what you carry than how big a bang you get with each trigger pull.

    How many test rounds in the Gun??

    I run 1000 reloads thru all of my guns before running a minimum of 100 test rounds of Carry Ammo thru each and the mags that they ran thru. This is a 100% no fail to fire or eject issue. I have had none fail and have not had to repeat the test. YMMV. I am comfortable with my Milage and I shoot Glocks, Para Ordinance, and Springfield Armorey guns. All have passed the test with no failures.

    50 high buck carry rounds mixed in with 200 target rounds. This test will cover all the bases.

    When breaking in a new pistol, I fire 100-200 target rounds before loading duty/carry rounds.

    Total of 400 rounds

    Clean pistol after each 50 rounds, or what the owners manal asks for.

    Clean the pistol after taking it out of the box.

    carry a revolver, shoot 50 shots... you are good to go.

    I think 50-70 shots in SD ammo is good.... and at least 200 rounds of various other types of ammo to see how gun operates with them. You will find some that seem to work better some times than others.... at least in some guns.

    I usually shoot about 150 or so, it hurts $$-wise, but in a gun you are counting on for your life how can you not. As an aside, I switched from a Glock 17 to Glock 19 a couple of years ago and found the 19 to be much more finicky with carry ammo. I shot much more through the 19 just because of the hiccups. In the end I never got comfortable with the 19 due to the occasional feeding issues, so I went back to the Model 17 which has never had a hiccup of any kind with any ammo.

    Assuming you've already run range ammo thru your G19 with no problems, I'd say one box of SD ammo should prove its reliability. After all, it's a Glock; it will either feed and fire, or it won't. It shouldn't need the "break-in" that some other makes require.

    I ran about 500 rounds of range ammo from varying companies (Speer, Federal, Remington, Magtech, S&B) with my Sig first then ran about 130 rounds of varying Gold Dots through it. 80 124gr, 20 124gr+P and 30 147gr. I did that as a test just because you never know what will be available these days. I'll probably run a few more magazine of 124gr though it next time at the range since thats what I have on hand right now.

    It's eaten up and spit out everything I've fed to it so far.

    i run a box or 2 (50-100) of my carry ammo through depending on the gun but i run em through a dirty gun that has had several hundred rounds through it previous...i'm not counting on my gun being clean when i need it and want a worst case scenario to prove there arent any issues...the real world isnt a clean place and you dont know what you might have to drag your gun through to defend yourself..

    if its gonna cycle the rounds its gonna cycle them...it shouldnt take several hundred to prove theyre gonna run through the gun...

    100 malfunction-free carry rounds *PER MAGAZINE*. Repeat with new mags or change of ammo. Even at todays prices, ammo is cheap, my and my wife's lives ain't.

    With pistols I run 100-150 of FMJ then 50-100 carry ammo. Wheel guns? 20-30, THAT'S why I carry a revolver.

    I agree.

    This is one reason why I don't always carry "the latest and greatest" in ammo. I have to be able to buy enough of it to test, and it's been a long time since I've used less than 200 rounds to test the functioning of my guns.

    With revolvers I'll do 50-100 rounds, but "bottomfeeders" are a different story.
