Being very pleased so far with my SA 1911-A1 in 9mm, I'd like to get a few more mags for her. CDNN has Chip McCormack 10 rnd .38 Super mags for what I would consider a reasonable price. Will these work without adversely affecting reliabilty? I may someday get a 9x23 conversion barrel and these mags should work for that application. Anyone with direct experience on this matter?
