OK guys, thanks for all the info, incouragement, & help w/ the problem. (A few chuckles along the line too.) Here is the morning drill report & I think it is all good. Had one premature slide lock w/ the 1st mag tried. after that not a failure. Shot over 200 rounds. Shot slow fire, rapid fire, doubles, & triples. It seemed like the spring just needed a little using. Do recoil springs need breaking in? My other replacements have not. In reading all the fine print on the Wilson Spring package, 2 Q's came to mind. It said these were "heave duty springs" I compared them w/ my other Kimber spring. The spring wire was just noticably larger, looking real close.

Also it said recoil springs should be replaced every 400 orunds. I read it twice. Was this a misprint or a marketing ploy?

If 400 is the recomended change time there is no way most of us could keep enough springs in a wheel barrow to keep a gun loading. Looks good right now. I will still keep an eye on it for a little while. If I need more help you can be sure I will holler. Thanks, Thanks a bunch. Longtooth.
