Hey all, it's been awhile since I've been on here. I'm contemplating a 10mm for awhile, and while I generally prefer a commander 45 I don't want to have a gun built that won't reliably handle the heavy 10mm hardcast loads and am open to a 5" gun. I've heard (read) reports of erratic speeds due to premature breech opening, and occasional mentions of short-stroking ftf. Some seem to say a heavier spring ensures full burn and fixes it, others not so much. Any of you 10mm commander owners shooting a heavy critter defense load? Chrono'd them thoroughly? Any thoughts? Thanks! And if there's any DW or GI 10mm owners who want to sell, let me know, lol!
