I practice the most with what I carry. Glocks happen to be what I carry these days.... why would you do it with a budget priced firearm?
As far as "enjoyable", any of them are enjoyable, as long as they work.Wouldn't the 70,000 rounds have been more enjoyable with a nicer gun?
I guess "nice" is in the eye of the beholder. Ive had more expensive guns, not work nearly as well, or as long. I also no longer have any of them.
Glocks, while nothing fancy, are just plain old work horses. Accurate, and boringly reliable. I can live with that.
