An evolution (sidegrade) to the 1915 model, the 1917 features simplification unlike its previous model. The rear safety notch has been removed as now it has a safety lever only. The heel magazine release still stays and there are no means of slide stop aside from the follower, so removing the magazine will release its slide.
The .32 ACP is measly compare to its predecessor, but an additional round and slightly better sights might make up for it, additionally it is slightly smaller and more compact.
Model from Isonzo. Thanks to Kalamari for the help!
