If $G$ is compact, $H \leq G$ open, $V$ an irreducible $H$-rep, is $\text{Ind}_H^G$ semisimple?

Let $G$ be a compact group, $H$ a normal open subgroup, and $K$ a $p$-adic field (so that not all $G$-reps with coefficients in $K$ are semisimple). If $V$ is an irreducible $H$-representation with coefficients in $K$, is the induced representation $\text{Ind}_H^G(V)$ semisimple?

In this specific context, I'm thinking of $G$ as the Galois group of a field, if that's helpful.

Thanks in advance!
