I made the decision to go with a 45 Super recently, after looking at the 10 mm. JWP was very helpful and advised what was necessary for the conversion and what velocities to expect. It was easy. I'm pleased with the accuracy and reliability of the 45 Super and with the ability to shoot inexpensive 45 acp for practice. At most indoor ranges, you can't help but lose some of your brass and I'd rather lose 45 acp brass than 10 mm brass.
