Actually they do in a way. Walther istelf does not as the 45acp is and never has been popular accross the pond in Europe or abroad for that matter....only the Chinese played around with it in their military years back. However S&W...who imports and makes some parts for the Walther p99 series makes their carbon copy S&W99 in 45acp. It has a longer barrel at 4.5inches and a 10 round mag. Looks pretty badass really. You can look at them on their website.
