To whom it may concern: I have a lightened .38s commander slide on my combat commander. I understand this is unusual but not rare. I would like to know what the Super shooters are using for recoil springs eather alloy or steel. Also, dose the lightened slide develope more slide speed? I want to replace the original spring. I am not biased about variable power springs over non-variable and I use shock buffs. Is their a CMDR spicific buff? Who uses them and in what combination? I know nothing about .38super except that I really want to shoot this gun and keep it running right. I'll carry 125's and practice with 130's.
