If I go to the range, 2-3 guns is my max, well, because I only own 3 guns, a CZ 75D PCR, a Lee Enfield, and a CZ Scorpion
. Just bought a Vz 58 tactical and waiting for it to ship
As for that gentlemen's comment on getting used to one gun, I'm feeling mixed about it however I think it's very situational.
Give me a gun and enough time to line up the sights and fire, it's a bulls eye all of the time. On the other hand, I got the chance to practice body armor drills (one shot to the body then another shot to the head within five seconds) with a friend of mine for his qualifications. Five seconds doesn't seem a lot but it definitely adds some pressure, and it's there where I think practicing one gun would be beneficial, but then again, if you got your fundamentals down then you should be good with any gun.
Finally, I heard about a guy from China who practiced with an airsoft blow back pistol for a competition in the US. He ended up going home with a few trophies that day. Don't know for sure about the whole story, but it just goes to show you about getting your fundamentals down.
Cheers
