My number one suggestion would be to try live fire with your trigger in different spots on your finger.  As with Glocks, often the shooter's hand is not perfectly sized for the standard grip, and it often causes a right handed person to push the trigger (and the muzzle) down and to the left.

I was able to overcome that mostly by attaching the grip backstrap on my Glocks to make the grip deeper, so the knuckle of my trigger finger is more in line with the rear of the trigger. 

I discovered this by sitting very still and very slowly dry firing the Glocks.  As the trigger fired, i saw the muzzle end of the gun move left.  After trying to compensate with different finger/knuckle positions on the trigger, I finally remembered the backstraps.  Viola!

So, first identify the problem.  If your trigger finger is moving the muzzle, you need to then identify why.  Maybe adjusting your weak hand grip will prevent it?  Or use the isometric grip where you press the hands against the sides of the gun but have a more relaxed grip.  Sometimes holding the grip way too tight creates a situation where you're so focused on grip pressure you miss everything else.

Let a friend shoot your gun and see what they can do.  I've shot bad and had a much better shooter use the gun and it worked fine.  Indian, not the arrow.

Start at 3 yards. Until u can put all 10rds inside a golf ball, don't increase the distance. Then go to 5 yards and same. Then 7 and tangerine. Then 10 yards and orange.  Or something like this and do slow fire.

Then increase speed if you can constantly get golf ball grouping or orange groupings.

Was that directed at me? or Begle?

If at me, apples and potatoes comparing 43x/48 and 19/17 etc.  I get that you're saying and yeah, I've tried/experimented and noticed.  But I wasn't referring to forgiveness on trigger pull/manipulations. More generally differences in grip sizes and individual grip/hands. 

The 43x & 48 don't come with backstraps, at least mine didn't.  I believe they have aftermarket.

ETA: And yeah. Dry firing, esp with red dots, you can def see more of when the gun is being "affected" but grip pressures, trigger pulls, etc.

Not at anyone in particular.  Just a suggestion spelling out what helped me identify the problem.

I was interrupted mid-post, so i skipped over one other anecdote:  I had a Glock 42 .380 Auto.  Micro sounds too clinical.  This thing was tiny!!

i let several very good shooters try it at the pistol range.  They were lucky if 1 out of 5 shots landed anywhere on the target.

I was able to get 4-5 on target, and at least half of the total were acceptably close to the bullseye.  Had to manage expectations.  Can't expect quarter size groupings from every pistol you use.

I'd never use the G42 at 25 yds for real, or even 15 yards.  It's designed for up close and personal encounters.

What i'm getting at is it takes practice and a lot of analysis if you're not getting the results you need.  Maybe my experiences are different, but maybe someone else can find something useful from reading about them.

 

Been shooting the 48 MOS more lately, including in a local match.  Was using Shield mags (blocks to 10 of course) and will be going back to OEM mags, at least for now.  At least for now.  I did a bunch of research on the Shield mags prior to trying, and even with the Gen 3s, seems to be hit or miss.  Was willing to try for myself.  I wasn't getting that many malfunctions, but enough to at least take a pause.  I am thinking it might be a matter of springs and/or other things having to work in, but even then, not sure if I'll be going back.  I intend on shooting the 48 a lot more in matches over the next many months here and there.  I will eventually get back to trying/testing the Shield mags, but for now, they are on the bench. 

I've had the 43x for a while and was using OEM mags.  I had recently switched to the Shield mags with that gun and it functioned fine.  I did notice a slight hiccup going into battery when I was testing Gold Dots, but otherwise it functioned fine with both OEM (100%) and Shield mags.  That's one of the guns on my HPD CCW, so will have to be sure before going with Shield mags on that gun moving forward.

Are those mags in stock all the time?  WHen I looked into getting a G43 (6rd gun), the 10rd Shield mags were often out of stock. This was why it fell off my CCW list. Plus they make a G43X.
