First. Get someone else to shoot it.
Second. Try different ammo.
Third. How does it shoot at 4 yards and ten yards? Unless u have a bad bullet, your closer distances will tell u if u or the gun. A bullet doesn't magically go off course at 25 yds

Thoughts?

The latter is a hard reality to face.

Best,

If you do this, save yourself the time and money and get the CZ customs Accu-Shadow, or at least get their trigger job. I have a SP-01...fantastic gun, but the triggers suck. Bad. It's definitely the weak link in the gun. I wish I'd have just got one from CZC and been done with it.

Try several different types of ammo...weights, brands, etc.

Just be glad you aren't having this trouble with .45acp or 10mm...that gets expensive.

AFAIK the KKM barrels don't have the right twist for 147gr bullets.
Concentrate on 115gr loads.

I will give the 6'oclock hold a shot. It looks like that's where the KKM is hitting anyway.
Using a six o'clock hold gives you a specific, repeatable point of aim instead of trying to consistently aim at the 'middle' of that big black spot.

If you're trying to aim at the little red spot in the middle of the black, you are most likely focusing your vision on it (the target) instead of where your focus needs to be....on the front sight.

I'm guessing that would be a very clear statement to me if I lived in California???

I was kinda wondering what kind of groups you were getting with the G17....

That is poor grouping for either a stock or aftermarket barrel/gun.


When you rest the gun on the bench (sand bag?) are you forcing the dust cover up and pushing on the slide? Putting a lot of upward force on either the magazine or dust cover might in return put upward force on the slide. When you bench rest the Glock it is better to rest the trigger guard on the block/bag.

LOL!!!

These are quality pistols. No after-market barrel is going to make any real increase in mechanical accuracy. If anything, as the OP has clearly demonstrated, they will be LESS ACCURATE with an after-market barrel. And the lock-up doesn't matter one bit.

So.

Return you pistole to stock, and continue shooting it. Stop wasting your time and money on after-market crapola, other than quality trigger parts, which a G34 shouldn't need.

Oh, and Glocks aren't target pistols, even the G34. They're service pistols, meant to be reliable and accurate as the shooter can be with them.

First test was with dust cover resting on the bench rest, but I wouldn't say I was putting a lot of pressure on it.

Second test was done with mag supported on a sandbag, and also wrists supported by the sandbag (gun touching nothing).

No one is saying it should shoot 1" groups at 25 yards. Many people with the 34 can get 3" groups. This gun seems to be be getting 5-6" groups with this ammo and two barrels.

OP, I have no problem with hitting 4" diameter clay birds laying on the bank at 30 yards out, two hand hold, standing.

That's with my Glock 17 gen.3 stock with the exception of bomar rear sight and aro tek front sight. That's with win. white box 115gr. ammo.

I would have to say that your 34 is capable of better groups then what you're getting.
Just a suggestion, find a great shooter and let him try your gun. If he gets the same results then you can be eliminated as suspect.

That's the plan, along with trying this out:

I was going to suggest the opposite. Keep replacing Glock parts until there is no Glock left.
It seems to be what makes him happy.

The problem is not "this gun".
