Three possibilities (there are many more; search the pgf manual for the arrows.meta library); adjust the settings according to your needs:
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,shapes.arrows}
\begin{document}
\begin{frame}
\tikz\draw[->,line width=8pt] (0,0) -- (3,0);
\tikz\draw[-Latex,line width=8pt] (0,0) -- (3,0);
\tikz\node at (2,0) [fill=black,shape=single arrow,text width=2cm,text height=2.5ex] {};
\end{frame}
\end{document}
