Get Sigma 100-300/4 and be happy With K3 you have same reach as 150-450 on FF
Btw what is wrong with Sigma 50-500? It is not that bad, but eats light quickly, needs F8+ and fast shutter speeds...

K3 + 50-500/4-6.3

I find F/7.1 to be the sweet spot with the Sigma 50-500 DG OS HSM, but it has no issues with wider apertures and of course not all wildlife requires a fast shiutter speed...
