I'm going to disagree about using grease on 1911's sorry, but I only use Wilson Combat ULTIMA-LUBE Oil it's ideal for temps.rangeing from 150deg.-10deg.it stays slicker than grease.Grease has a tendacy to "gum" up when the weapon starts to get dirty form shooting,I have had this problem in the past and since I swicthed to oil no problems what so ever,as far as your extractor problems you may ned a new one,allso like someone said before go ahead and change the recoil spring out you can go with the 16.5pound-to an 18pound spring,wolfe springs are great I personaly use an 18pound spring in my 1911's,allso make sure you do a complete detail strip,and a complete cleaning of your gun at least every 1500-2000 rounds that way you can inspect it for worn parts and can lubricate the sear,hammer strut and trigger,I recently had to replace a sear spring in my Les Baer that I found broken,and that 1911 is brand new with only 500rnds.ran through it.Get your self a good book that explains in detail how to do all of this,believe me once you do it a few times it's simple plus you get an understanding of how the 1911 works.Here is a good book for info.on the 1911.THE M1911 COMPLETE OWNER'S GUIDE by WALT KULECK,it has all the info. you need about the 1911.Good luck with your's and I have a feeling it won't be your last one you or your husband will buy.
