While the CS45 mags will fit and probably function, I would not use them for serious purpose.
Heres why. The CS45 mags have two detents stamped in either side of the mag. These were placed there to keep the next round up from moving forward under recoil.
I have shot all the S&W 45 mags in my 4513TSW. The 8 round, 7 round and both the OEM 4513TSW 6 round mag and CS45 6 round mag. While my gun has never malfunctioned with any of those mags, when carrying it on or off duty I only used the flush fit OEM mag, with a 7 or 8 round mag as a reload. Regards 18DAI
I picked it up yesterday. I gotta tell you this is one sweet gun. I love it. As a plus, it is in far better shape than I ever expected. Virtually zero finish wear and the internals look almost brand new. I probably will not be able to shoot it till this weekend however. Now I must begin my search for holsters.
“I used to be totally into Steve Vai and Joe Satriani and other shredders, and I tried to emulate what they did and really grow as a guitarist,” Mr. Hanneman said in “Louder Than Hell.” “Then I said, ‘I don’t think I’m that talented, but more important, I don’t care.’ ”
