Went shooting with my son, who is just back from Kuwait,
We took out a 45 Long Colt (Uberti), Ballester Molina 45 ACP, Mitchel 357, and my 1914 Erfurt Lange. With the Erfurt, the ammo was some of those gun show "Reloads" 125 grain Total Metal Jacket. They were fine, but I'll probably stick with a different load next time, as I really had to hold the grip tight and then it functioned great. I remember this happening with the 1911A1, but I didn't remember this happening with the Erfurt.
BTW, we had a great time!
