I don't have any experience with .38 Super, but I've been tempted recently to pick up a Rock Island 1911 and give it a try. I've been a fan of Paul Harrell for years, and he prefers the .38 Super in 1911's. I've also been able to find .38 Super ammo in stock much more often than 9mm recently. The only thing that has stopped me is that .38 Super ammo seems to be selling for about $29 for a box of 50 rounds, which is pretty close to what I could order 9mm ammo for online. I may eventually make the purchase if the ammo drought continues much longer.
