I bought a Tec-9 a couple of weeks ago and have been shooting it with my standard 9mm load, and managed to break the operating handle. That seems like a sign that my loads are too hot for this pistol. The load is 4.2gr Hogdon Titegroup under a 124-125 RN or TC powder coated booliit sized .358". I have been with this load a long time. It does well in my CZ75B, G17, and BHP, but have never had a 9x19 pistol with a blowback action. I realize that this load is heavier than the max 4.1gr charge recommended by Hogdon, but that load gave me only 980fps average in my other 9mm pistols, so I increased it to 4.2grs for just over 1000fps. Brass slings about 5-6 feet form the Tec-9 with this load. Pretty obvious that this load is too much for this pistol, but I thought I would run it by you guys for opinions....DanM
