We may be talking in circles.
Is the point to achieve a reduced grip? or is the point to make the gun fit the individual?
Lots of people chose the Glock (or any other handgun) for myriad reasons…just like I said at the beginning. Too big a grip is not going to be a disqualifying factor for someone who prefers the Glock.
Would the Glock be improved with an interchangeable backstrap? I’d agree, but then their sales don’t seem to be suffering.
lol, i’m definitely going to get Todd’s M&P when it’s available…
I’m a 1911 guy and i’ve never given the glock a fair shake as it’s felt “slippery” in my sweaty paws and seem to turn in my grip as i squeeze harder. i’m pretty sure i’m going to get one to train with and maybe compete with it. i just wanted to know what the process was if i wasn’t completely happy with the gun and i wanted to mod it (a habit with my 1911’s).
Tinkering with a 1911 is almost a rite of passage. Not for the shooter, but for the gun. A 1911 isn’t a real 1911 until it’s been tweaked or personalized in some way. 
A modern service gun shouldn’t require that. But that doesn’t mean it’s wrong to change grips, sights, etc.
While I’m certainly no Glock cheerleader, if the only problem you’re having is traction I’d recommend getting some skateboard tape as a start. Tacky up the gripping surfaces and see if the gun runs to your satisfaction. If so, you can either leave the tape on or, if you’re going to be carrying it, you might want to have someone stipple the grip frame for you to make it coarser.
I did the grip tape on my 2 rugers and it’s the best thing I’ve found to improve grip on the gun. you can usually find it in the paint section of the hardware store in 1-6" widths
I’ve never seen any of these Glock, hack grip mods that didn’t look like a meth head with a soldering iron went ape shit on the frame.
There’s just too many special needs shooters in this world.
I think the guy that did mine did a decent job. Had him add in a magwell and beavertail. May not be everyones cup of tea but it fits my hand perfect now and grips better. At least it doesn’t look like a gallon of bedliner was poured on it.
Pretty is as pretty does. Heat stippling works. Nothing pretty about the Glock to begin with.

Spoken like a true right-handed, left-brained shooter.
