Yes1. Is 9x19 Wolf a better choice than .40S&W Wolf, since kb's and overpressure isn't as much of a concern in 9mm?
It is fine if you keep it clean. Firearms with tighter tolerances will give you more trouble though.2. Does the laquering and steel case directly harm the pistol, or is it a function of improper cleaning?
S&B3. If the Wolf stuff isn't a good choice, what would be another good, inexpensive practice ammunition?
Why try saving a few bucks this way
