I aquired an early Detonics Combat Master. It looks to me to be in great condition. Very little wear. Finish is excellent. First time at the range though it failed to extract half of the seven rounds.
Back at the work bench I noticed that the extractor seemed to be a bit loose. To compare I checked my Springfield 1911 and this one was tight. Assuming some of the internals might be interchangable I dissasembled both guns to compare the extractors. Where I had to drift out the Springfield's unit, the Detonics all but fell out the back. On closer examination of the Detonic's unit I noticed that some of the bluing was polished off one side. It didn't look like wear but a deliberate polishing.
Why would someone do this? Especially when the results made the mechanics worse.
The Extractors look almost 100% identical. I'm not a gunsmith so I wouldn't try anything creative, but would it be possible to just replace the old Detonics extractor with a generic 1911 unit? I'll certainly take this to a gunsmith if it's any more complicated than this - but if it's as simple as dropping in a new piece I'd like to do this.
Does anyone have any thoughts on all this? I can see why a loose extractor will fail to pick up the case, but could it be possible that the previous owner was trying to solve some other problem? Like the extractor beating up the case?
It's an awesome gun. I'm hoping the problem is easily solved.
