Hello. I am new tonight to this forum and am seeking direction from those more knowledgeable. I have a LW Commander purchased NIB in 1967. After years of hardball, handloads, and some hot Super Vel ammo the aluminum frame developed the usual crack. Colt eventually replaced the frame but the LW went into semi-retirement about 20 years ago. It is time to get it back to active duty and even though it functions well I have been considering replacing the recoil spring and maybe others. Any suggestions/recommendations would be appreciated. Thanks in advance.
