Commander FTRTB Issues with New Mags

[ColColt]

It is beveled. I got the Weigand Tension gauge today with the tension gauge set and upon checking tension per the instructions, the extractor is way too loose. I think I read it should be about 25 ounces plus or minus a couple and after four different readings to be sure I was reading the scale right, it ran between 8-10 ounces...way too light. I'm going to adjust to 25 ounces and see how well it will hold a round now. Before if you put a round under the extractor with it lined up with the firing pin hole and shook it a bit it would fall out.

I know too loose an extractor will cause extraction/ejector problems but with it that loose maybe it's causing feed/FTRTB issues as well. I didn't really have any extraction or ejection issues just a sporadic feed issue and FTRTB problem.

I set up the tension at 28 ounces. We'll see what happens at the range next time. Neat little gadget this tensioning tool and gauge.

Tuner-I thought I'd bring you an update on the previous measurements I made with the cheap plastic calipers. They were not giving the proper measurement, needless to say. I bought some new calipers(stainless steel) affirmed they were zeroed and remeasured the distance between the guide blocks and turns out they're .487"-well within range.

Friday, after reaffirming that and retensioning the extractor, I'll go to the range and see how things go.
