Tec 9s arent so bad. Its like any gun, right mags, and right ammo, and she'll run all day. Non-OEM mag or crappy reloads, plan on spending some time removing jams.Only thing worse than a tec 22 is a tec 9 so I hear. The original ghetto blaster. Thugs love them and so do cops because they know the bad guy is only going to get to shoot once.
Tec22... its a semi auto 22... Its going to jam. I have had a tec 22, 10/22, beretta neos, GSG5, and a few others. Beretta was the only one of them that would reliably fire anything I fed it. 10/22 is for the most part stock but only likes only a few different mags/ammos, tec22 reliability isnt that much different. GSG I have is just worn out, and is less reliable now that I "fixed" all the problems with missing/loose hardware. I keep it to tinker with in hopes that one day it will eat a full mag of mini mags without a hiccup.
My buddy has a sub2k, and I have seen him put thousands of rounds threw with no issues.
