I have a Bui M5 in .38 Super, this is a polymer framed 1911. It has been 100% reliable in the 3000 or so rounds I have put through it and I have achieved my best auto-loader grouping with it, 1.5 inches for 5 shots at 25 meters with winchester silvertips.
I'm planning to offload it though. I don't shoot it very often, as I've gotten older I've become more of a fan of blued steel and walnut and factory ammo is twice the price of 9mm. Here in OZ I can buy 9mm for $21/50, .38 Super is $48.00 for fmj.
Given the above a 9mm Colt 1911 will see more range time than a plastic .38 Super Limited gun.
