Alignment of custom item symbol in beamer

Question

Consider the following MWE

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
\item a
\item a
\item[$\Rightarrow$] a
\end{itemize}
\end{frame}
\end{document}

I would like the rightarrow has there left side align with the left side of the triangles.

Dirty hack:

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
\item a
\item a
\item[$\Rightarrow$\hskip-0.15cm] a
\end{itemize}
\end{frame}
\end{document}

Not so hacky:

\documentclass{beamer}
\usepackage{calc}

\setbeamertemplate{itemize item}{%
    \makebox[\widthof{$\Rightarrow$}][c]{%
        \scriptsize\raise1.25pt\hbox{\donotcoloroutermaths$\blacktriangleright$}%
        \hfill%
    }%
}

\begin{document}
\begin{frame}
\begin{itemize}
\item a
\item a
\item[$\Rightarrow$] a
\end{itemize}
\end{frame}
\end{document}

think, it is work in a real use, if I do some little modification. – Maïeul Oct 12 '16 at 11:11

What about this solution?

\documentclass{beamer}
\usepackage{amssymb}

\begin{document}
\begin{frame}
\begin{itemize}
\item[\usebeamertemplate{itemize item}\hspace{4.6pt}] a
\item[\usebeamertemplate{itemize item}\hspace{4.6pt}] a
\item[\(\Rightarrow\)] a
\end{itemize}
\end{frame}
\end{document}

The default itemize symbol is in \scriptsize, in case you want to be consistent with other itemizations in the presentation. – samcarter_is_at_topanswers.xyz Oct 12 '16 at 13:02
Thank you @samcarter! I've corrected my answer according to your suggestion and also modified it adding only a little space after the itemize symbol instead of the phantom (it is more precise this way, even if it is similar to your first solution). – CarLaTeX Oct 12 '16 at 13:15
I prefer the first solution, which don't force to modify all \item entry. – Maïeul Oct 12 '16 at 13:42
@Maïeul Don't worry, you have already accepted samcarter's solution, that shows your preference. My answer is only a possible alternative, maybe someone else could find mine useful! :) – CarLaTeX Oct 12 '16 at 14:00
@CarLaTeX Please feel free to roll back the edit in case you don't like it. – samcarter_is_at_topanswers.xyz Oct 12 '16 at 15:00
@samcarter I like it, it is more elegant! – CarLaTeX Oct 12 '16 at 15:08
