Help diagnose my shooting problem

**ryu_sekai** · 03-23-12, 22:24

I kind of at a lose and cant figure out what is wrong with me and or the gun.

Here is a quick break down so I don't have a wall o text.

Up until recently I have shot my Glock 34 17 and 19 very well. I usually start by shooting at 7 yards, and all three guns are literally same hole at that range. (not clover leaf, but same hole.)

So all is good, and one day I shoot my 19 and groups have opened up to about an inch with the 19 and group sort of shifted. I then shot the 34 with the same ammo and its still one hole grouping.

Day 2 I go to my Quals shooting 147gr HST and the 19 is back to being same hole. (messing around, one person fire one round and I shoot his round, 3 rounds in same hole at 5 yards)

Day 3 Glock 19 groups have opened up to about 2-3" at 7 yards. Glock 34 if is still same hole with same ammo. I did not bring any HST with me this time, I did shoot my friends SD rounds and group did not improve. I put my barrel in his glock 19 and its back to same hole.

side note when I shot his stock 19 i was also around 2" grouping and up until that day I have always been extremely accurate with his 19 as well as mine.

Is something wrong with me? What else can it be? I know its not the ammo.

One possibility is that you could have developed a flinch or are anticipating the shot. Since it is happening in two Glock 19s but not the heavier Glock 34, that would be my first guess.

I went through a stage last year (due to illnesses, busy schedule, etc) where I did not make it to the range to practice enough over the course of two or three months and began to shoot my P2000 in .40S&W erratically. I developed a flinch that was so bad I could not even shoot my USP Expert accurately (was pulling my shots about six inches at 25 yards) and the Expert is similar (for the sake of this thread) in accuracy to a Glock 34.

Try using one of these diagnostic targets to see if they help you figure out what you are doing:

If you can't trouble shoot your problem on your own perhaps a talented shooting buddy or a competent handgun instructor could watch you shoot to help figure out your problem.

I forgot to ask if your shots go in any particular direction / zone on the target or are they spread out in all directions? You mention the group shifted. Where did it shift to?

How's your dry firing going?

Also, try some ball and dummy drills at 25 yards on a B8 target.

VERY difficult to analyze shooting problems across the interwebs.

But if it is a possible flinch, have a friend load a couple of magazines and put a couple of dummy rounds in them. Just no dummy rounds for the first or last round in a magazine. Mix the mags with the dummy rounds with mags with no dummy rounds so you won't anticipate the dummy round. When you squeeze the trigger for a dummy round, a flinch will show.

It is centered but the grouping is large. not in one direction

I will do that. I am wondering why i am only doing it with the glock 19 and not the glock 34. The 34 is a blue labe so it has the reg connector not the 3.5/4.5. Is it possible to have a flinch one day and not the next?

How many rounds through the 19?
Very possible that wear has caused loss of solid lockup.
You sound like a competent shooter, try another 19 and see how you shoot it.

The 19 has about 1000 rds though it, my 34 has about 3000.
