Can anyone tell me if there are any captive spring conversions for the CW9, CW380 and CW45? I am an older shooter and struggle with getting the guide rods/springs back in, a captive spring would be a definite fix. I have a CM9 and it is easy for me to reassemble, why can't the CW series be as such, I do understand that there is a difference in fit , finish, but could Kahr make this available?
