What I really like about the Proto is the handle forward design, its so well balanced and light making it super easy to work with for longer periods.
Proto impact
I bought my 231 in 1989. It's never been apart. With 150psi going to it it can remove lugnuts from 18wheelers.
That's about when I bought mine, never been apart, still in service. The IR 231 has been the bench mark for decades in my opinion. It was the most powerful impact of that time, and I had a 3 year old Snap on impact that would not remove crank harmonic balancer bolts. The IR 231 did! Back in the 80's, Snap on, Bluepoint, Mac, IR air tool were really not that expensive. Infact, nothing was that expensive, now everything cost an arm and a leg!
Back in those days torque numbers were more realistic than today, the 231 on paper was less than half as powerful as today's guns but as you say it still hits harder than many of the new ones.
After about 10 years I put a kit in it with new rotor blades, it really made a difference, a couple of years ago I did the same thing, with new gaskets and seals. Not bad for a gun that has seen service since 82 or 83. Too bad the original leather protective boot let go years ago.
