In the moment, when she was going to save Jaune's life, the form change was slowed down to make it look cooler. It still changed at normal speed In-Universe.

And she does use the Rifle form (Yes, it's a rifle, a semi-automatic rifle. Any real man could see just by looking at it that it's not a shotgun), it's just that she doesn't use it as much as Sword and Spear form.

And considering how she can't really do anything practical with her shield while firing Rifle Miló, while she can use it more practically in the other forms, it's understandable.

And it does transform fast anyway. It switches repeteadly and quickly between spear and sword and at times rifle during the Pyrrha vs CRDL fight, in case you didn't see because of the awesome action.
