Amen, Tamara.
As usual, you distinguish yourself from the herd. Thank you.
Were it only that 99% of the
other gun shop workers could be as knowledgeable, competent
and ethical.
Unfortunately, most gun shop people invariably make the counter-help at McDonald's look like geniuses.
This is especially true where the 10mm Auto is involved, since it - unlike virtually any other modern cartridge I know of - is subjected to scorn, misinformation, and double standards which other calibers seem to escape.
As to the original poster's inquiry, please - have no hesitation in selecting the G-29, if it's size, compactness and concealability is to your liking. Personally, I've only seen one post on GT about a problem with a G-29, and the poster later reported that Glock corrected it under warranty and the turn-around was quick.
My opinion is, you won't have any problems with your G-29. The gun was specifically designed, like its big brother, to handle the punishment inflicted by sustained firing of hot & heavy 10mm ammo (i.e., 200gns @ 1200 fps).
Remember:
any gun maker can, and has, let a lemon slip out of the factory. The issue is: (1) how often does this occur? and (2) once notified, how fast do they correct the problem for the customer w/o attitude? (i.e., customer service. And, trust me, there's a world of difference between Glock's customer service and, say, EAA's).
Go for it.
