Also the [Delta Elite] 10mm had a reputation for cracking the frame at the slide stop hole. I saw one crack after only firing a 50rd box of Norma ammo.Because bailing the Titanic with a teacup is a hobby of mine, I had to reply.
Just in case anybody stumbles across this thread via search engine in the future who isn't familiar with this issue, early Colt Deltas would crack the frame rail above the slide stop cutout. This was no biggie, since the slide stop cutout effectively stop-drilled the crack, preventing it from propagating, but "zomg Delta Elites crack their frames!" became such a staple of the gun store commando that Colt fixed the problem by removing that section of frame rail.
Despite this fix being applied several years before the letters "www." meant anything other than the "w" key on your IBM Selectric was stuck, it somehow persists with guys like the one I'm quoting.
Oddly, they all talk about the "zomg Delta Elites crack their frames!" thing, and yet none of 'em ever comment on the junky plastic recoil spring guides they came with that disintegrated in short order under a diet of Winchester Silvertips... Makes me wonder how many of them actually had any time with the pistol in question.
