While cleaning my SR22 after an recent range visit I noticed some wear/damage starting to appear on the slide. There is a "dimple" forming at the aft end of the area where the slide catch lever rests when the slide is locked open, and evidence of the slide catch rubbing along the bottom (photos below). I did not find any vendors offering a replacement slide for this pistol so I'm assuming my only option is to send it in to Ruger for repair/replacement. However, just looking at the Ruger webpage regarding the cost of repairs it looks like I'd be on the hook for $30 (labor) + price of a new slide + $45 return shipping + initial shipping to return it: roughly $100 plus the cost of the slide which is not given on the Ruger site. Even a conservative estimate of another $100 for the slide itself gets me to roughly half the cost of just buying a brand new SR22. So, has anyone else experienced this kind of wear? Should I "bite the bullet" and send it in or just write this pistol off and start looking for another plinker?
