Just curious as to how many of you that happen to read this have changed your backstrap? My XDs 9mm 4.0 came with the larger or the two backstraps installed (I'm guessing they all come that way from the factory).
I took a tactical handgun class a number of weeks ago, and did fairly well. I had tight groupings during most of the exercises....but for some reason those groupings were always just slightly low and to the left.
I'm "guessing" this has more to do with trigger control than which backstrap I have on.
But...as I prepared the other night to put some new Talon grips on my XDs....I thought, "I really ought to see what that other, smaller backstrap feels like before I wrap my grip in Talons....
So....OF COURSE....now when I have the smaller backstrap on and dry fire...it feels GREAT. And when I have the larger backstrap on and dry fire.....it FEELS GREAT !?!?!? : \
I'm very average build, height, hand-size..... I know everyone is different....but what have most of you ended up with on your XDs.....Smaller or Larger backstrap???
How you as an unique individual "finishes flat" is just that: how you as an individual must do it.
Your physical build - your anatomy: the size of your hand, the length of your fingers, how your fingers articulate, etc. - will affect how you mate with the gun, and that elusive "ideal" trigger finger placement is something that you need to find, for yourself.
The equation is a simple one:
[ sight package ] + [ trigger path ] = [ hit ]
The ability of you and any other shooter to execute each of the two left side factors towards perfection determines the amount of deviation from perfect you will see on the right side of that equation.
For the vast majority of good shooters, the sight package is easy enough. It's trigger control that gets - or gets away from

- us.
A good shooter, after some familiarization, will be able to adapt him or herself to any weapon's trigger path. With this being your personal weapon, you have the luxury of being able to tailor it to you. See if swapping backstrap sizes can help you achieve that "finishing flat" ideal, and note that there are non-traditional takes to this outlook, too, such as that of Pat McNamara's:

The take home: what works best/better for you as an individual may or may not be what others find to work well for them. Find what works for
you.

Mine are low left also and dead mose 1.5 inch shot group with the xdm. I changed the backstrap to smaller now i am just low. Guy at gun store suggested i not shoot a dbl stack at all and just the xds for about 50 rds. See what happens. Switching backing and forth between the 2 could cause bad aiming. I am getting ready to try it now.
So i went out took my time shot 21 rds at 21 ft. It is 29degrees out in central michigan. My last 6 frnds first 2 dead center next 3 up and down but center last one dead center. So it is the Indian in my case not the bow n arrow. Also need to understand outside 30 or 40ft the xds is not your go to gun. Yes ppl can hit center mass with but not not ideal.
You just said it yourself - it's the shooter behind the gun that's the biggest limitation.
Is 10 or even 20 yards the real limit for the XD-S, or is it actually *_your_* limit, at your current skill level, with this particular gun?

I recently switched to the smaller backstrap just to see if it has any effect on accuracy. So far it feels like my thumb has moved to a spot that feels like a more secure grip with the shorty mag, but i'm not seeing a real change to accuracy or speed for follow up shots.
This brings up a great point.
When you (anyone, not just you

) change to a smaller backstrap, take note of where, if you are right-handed, dominant thumb comes into contact with the gun, particularly in relation to the slide-stop/release button.
You may need to adjust your single-handed grip as well as your double-handed grip (again, both assuming that you are a right-handed shooter) in order to avoid accidentally engaging/(ore more likely)disengaging the slide-stop with your thumb.
