Does anyone have a copy of Unison Service Letter SL2-93 or know where I can find it? I have sent an e-mail to a Mr Ben Taylor at the literature department at Unison and am waiting for a response. I currently have an O-320-E2G that I am converting for use on my 9A and one of the things I would like to do is install two Slick 4371 mags with impulse couplings and I believe this letter has information specifically relating to this mod. One of the main reasons I am doing this is I have two very low time 4371 mags available to me where as I would need to acquire a slick 4370 with the drive gear if I were to keep it original. Thank you in advance for any assistance you can provide.
