Hi everyone! I was told there might be some guys on here that can help me with my Witness. I have the Witness .22/.45 and I am looking to get the 10mm and .38 Super longslide conversion kits. I have heard the Witness has problems with the slides and frames cracking so I was looking into Wolff replacement springs. I am not sure if I need them or which ones to buy if I do. Can anyone help me out with this?
