I will add just this..
...
Not the same gun, but..
When I got my Colt Defender 3" 45, it starting jamming, feed wise only, after some 50 rounds.. It averaged on jam, after the 1st, 2nd, or 3rd shot, each mag, each load there on..
The range officer said: get 2 of those Wilson Combat mags off the wall, and your problem is solved, as the factory mags are not that good..
I did, and the worked for the next 100 rounds, then the same pattern of feed jams..
I sent a PM to 1911Tuner, who told me it was a "timing problem" and to make sure, both the mag interiors were clean and the follower smooth, along with the rails and guides were clean and "WET".. well-lubed.
So, I did this, took her apart, cleaned her good, and the same with both the Wilson mags, and the 2 factory mags, with EEZOX (synthetic drying lubricant for bonding to metal, it's on the directions of the can) Put her back together, and for extra measure, when I went to the range the following week, I added some more oil via the vertical method, just before I packed them up for the drive..
Well, she has shot at 100% since, and "both Wilson mags, and the Factory mags work 100%.
Try giving her and the mags a good cleaning, and see if you can use a Wilson mag, if possible, otherwise, hey, buy 2 of them, they're good mags and you'll have 4 total, can't hurt ya.. I'm real happy having 4 mags for her, that work.
See what happens, then report back..
Best of luck,
