Recently, I purchased a Colt Delta Elite and pretty much love it. However, I've seen Rocks put together with more attention to detail than this high dollar, "quality" can killer. I'm probably going to grab a 45 soon and was wondering if some of you have experience with both. I've popped the top off of a couple of sigs lately and it looks like Sig should be awarded the "quality makes it a ___" label. Smoother with less dings in the slide, apparently. I have not squeezed the trigger on one so I can't say personally. Not sure how I feel about the external extractor, but hey, if it works! I still love colts but it looks like (to me) the name is just keeping them alive. Bash away!
