    Shooting the Umarex Glock 17 gen 4

    I don't expect miracles from a smooth bore BB gun but would be interested to know if this is typical.

    The range was 7 metres and my aim point was the top left corner of the target:

    I read on another forum that the point of impact can be adjusted using the screw on the barrel assembly:

    This seems a bit unlikely to me. Anyone know better?

    Your second picture shows the hop up chamber. They can make real differences when using 6mm plastic BB's but to the best of my knowledge it will have no effect on steel BB's

    Does look a bit poor.

    I’ve only shot my Glock once at 10 yard cans and was v pleased with its performance.

    Have you tried not aiming

    Impossible to answer. The following may or not not apply:

    1. The gun is bad and should be returned and replaced.
    2. The gun is fine, they all do that. Sorry, that’s what they are like.
    3. The gun is fine but try different ammo.
    4. The gun and ammo are fine but that’s just how you shoot it. Maybe you aren’t a great pistol shot. Maybe you are, but it just doesn’t suit or fit you. That happens, sometimes.
    5. A combination of some of the above.

    Personally, I’d go for 1 or 2. That looks pretty poor. But have you tried careful slow fire from a rest to eliminate number 4? Or different ammo (number 3)?

    I wasn’t joking about not aiming!
    I think resting a bb blowback pistol and trying to get decent groups leads to madness.

    No I haven't tried it from a rest but I will give it a go.

    Shooting from a rest gave the same results initially, then after emptying a couple of magazines the slide started jamming open.

    I stripped the gun and lubricated the slide and there was an instant improvement.

    This target was shot from a rest at 7 metres aiming at the bull:

    Good enough for plinking!

    You failed to mention that the target is six feet in diameter
