considering how many simple to use autos are out there I would not be so hung up on glock. Is she does not like the grip she should try something else. There are LOTS of other autos that are just as reliable and have better ergonomics. Off the top of my head the S&W M&P, the SA XDs and lots of good ones from Ruger. Heck, just about every brand now makes something in a nice polymer frame. I prefer 1911 and can’t stand the glock grip. There is a very specific part of the front area that just sticks out funny. Bugs me no matter what grip I use. My XDm fits my hand like a glove and is just as simple, just as reliable, and just as accurate. Telling someone to ‘only’ go with the glock’ is terrible advice considering the variety of polymer framed guns out there.
Note that I personally do not own a Glock, as I stated I’m a 1911 variant guy, old school, and have several versions.
I am also a NRA Range Instructor with significant military experience. Have also taught hundreds of young people, introducing them to shooting.
For my daughter, the correct choice was the Glock for a variety of metrics.
That you pontificate that the Glock was “bad advice” is amusing. Perhaps this is a method of validating your choice of an XD?
Out of the box she put all 50 rounds into a target 30 feet away that could be covered by a dollar bill. Not bad for a “poor grip”. By the time she shot her second box of ammo she not only comfortable with the gun but her groups grew tighter.
For DA reliability, field functionality, accuracy and warranty the Glock was the proper choice for her first weapon.
