+1 to Shooters Connection.
I’ve been using safariland 773 pouches for my x5. I’ve been tempted to try others, but I’d still recommend them for the money.
RHT is a great option for the holster, fits the gun well even with the *thumb rest [generic]*.
If you do try Springer grip tape, save the backing. Mine only lasted a couple matches before tearing at the circle cut out, but the backing gave me a great template to cut more.
