Ed is correct, the highest capacity magazine for this model is 18 rounds. Even went to the FN site to check, see for yourself. FN eStore | FN eStore FN 545 Magazines https://share.google/5gMycoUeXAwGkR6EE

Hi Luther and welcome. Unfortunately, no. FN Specialties offers an 18-round factory magazine for the FN 545. https://www.budsgunshop.com/product_info.php/products_id/156708/fn+america+fn+545+45acp+18rd+magazine ------- Cheers and stay safe!
