So tell me about the Delta Elite and the Glock 20. My intended purpose for a 10MM is as a backup while hunting varmints at night. I also want a good shooter for some range time. I have heard some nightmare stories about the Deltas not hlding up to full power 10MM loads. I know there were frame cracking problems with the older Deltas. Have the newer samples with the frame relief solved the problem? The obvious advantage to the G20 is magazine capacity and durability. But now I am concerned with the MIM extractors. Any insight/experience would be greatly appreciated!
