I've been buying all the Tulammo steel case in .40S&W & .45ACP that I can get my hands on. The accuracy is very good shooting it with my Gen4 G-21 & G-22 . It's dirty as all get off, but you can't beat the price! I'd rather shoot Fed American Eagles, but it's hard to find, one LGS here is asking close to $30 a box for Fed AE in .45ACP, the Tulammo is almost half that much, so I shoot twice as much, and my G-21 shoots it really well. This is definitely good enough to shoot targets with, and these Glocks are not picky about the ammo you load them with for practice, which is the thing I like best about them.
