i lucked out on the practical- the"test " auto happened to be a beretta 92fs- my secondary since about 90 or so- the only diff was the mag release- but i was only upgrading from pol to rpal- wanted some new toys now that i'm retired- the only one i was unfamiliar with was the sks, as i have never had an intrest in the 7.62x39 ctg- however , once i got my hands on it. it became obvious where everything was- after that , it was just standard safe gun handling practice
