I have a P-11 with very high round count. Couple of days ago the slide stop broke. Is this something I should send back to KT for repair or request the part to try and replace myself? I've never had a KT apart other than to replace an extractor on a P-32. Know where there might be instructions to show me how to do this? If I send back to KT could I only send the recv and ship as machined parts to avoid high overnight shipping cost of complete pistol? Any help on this matter would be greatly appreciated.
