1/2 inch impact

I've used the CP 734 as my general gun,, it's light, slender, maneuverable, , and has the power to do 95% of what I need without wearing out my wrist..

If I need more umph,, I bring out the I/R,, it has the grunt,, but not as versatile as the CP,,

PS, My first 734 lasted near 35 yrs, with 2 kits,, I bought my current 734 about
8 yrs ago..
