Is it safe to specialize in automatic weapons from the start?

In Atom RPG, similarly to Fallout 1/2 you have to spend points to advance skills in specific types of weapons. It is not hard to guess, that akin to “energy weapons” (or “big guns”) in Fallout, “automatic weapons” in Atom will be most powerful, but in “Fallout”, those types of weapons weren’t accessible until the mid-late part of the game. So is it safe to start spending points in this skill from the start and ignore all other weapon types?

I am currently barely few hours into the game (just “joined” the bandits in the abandoned factory) and the best weapon that I’ve found is rusty Nagant revolver for which I have barely 5 bullets. Which doesn’t matter, because I couldn’t hit the wide side of the barn from 2 meters, so instead I rely on good old kicks to the face that surprisingly have 99% chance to hit. How soon can I find even entry-level automatic weapon?
