packard66, I will freely admit that I am a Glock fanboy. However, the .40 Glocks might not be the best choice. They are notorious for poor case head support in the feed ramp area and there are many documented cases of even factory, never-been-fired brass bulging to various degrees when fired in a Glock. Several years ago, I had a Glock 23 that suffered a case head separation with factory Federal ammo. Blew the mag out and the extractor off. I was unharmed but the gun had to go back to Glock for repairs. The ammo, admittedly, was defective but this, in addition to the rest of the .40 Glocks I have read about and seen, turned me off on them forever. I have also personally witnessed bulged cases with several .40 Glocks, both factory and reloaded ammo.
I have also experienced some of the reloading issues. I tried reloading for my G23, since I cannot afford much factory ammo. I had to download the powder charge to where the slide just barely cycled to stop the brass bulging at the feedramp. Admittedly, the gun was laser accurate- whatever I pointed it at, it would hit, out to 25 yds.
In the end, it depends on what you want to use it for. If it will be a range toy and you plan on reloading for it, I'd skip the Glock and look for another brand. If you plan to use it for a defensive weapon and can afford to shoot only new, factory ammo, then it will likely be a good gun for you. Even with the issues, the vast majority of .40 Glocks are fine and have never had a problem. Just stay away from older Federal ammo headstamped "FC". Federal ammo headstamped "Federal", with the whole word spelled out, is OK.
I have absolutely no idea how much they run right now. I have read that prices are up due to the high demand for everything gun related right now, though, so I'd expect to pay a premium. Expect an extra $50 or more for night sights, based on the last time I looked at them.
Good luck with whatever you decide. Myself, I'd go with either a 9mm or .45 Glock and completely skip the .40 in this make, but it is ultimately your decision.
