Yes, this will fit but since your girsan is a compact it'll stick out past the grip a little. This is for full sized 1911s. If you want a compact magazine that won't extend past the grip like item number M19119FR8SWB just type the item number into buds search and it'll pop up. Hope this helps.

Michael, yes, the Girsan 1911 uses standard 1911 mags, so this will fit with no issues. Have a great day!

Michael, it will fit no issue Sir. Mec-Gar is a quality magazine. If you want some extra capacity, I highly recommend the Chip McCormick Power Mag : budsgunshop.com/product_info.php/products_id/31060/chip+mccormick+stainless+power+mag+1911+45acp+10rd+magazine

YES, any standard 1911 9mm magazine will fit this pistol. Ed Brown 8rd mag works too. I hope this helps!
