the regular gun works fine, with loads WAY beyond what guys THINK is ok in a 1911. You just have to wake up and use the lighter, 165 gr jhp loads, or the CorBon PowRBall that's all. At 1300 fps they are still quite controlable in a full size and wt 1911, ditto at 1200 fps in a lw Commander. Because they are 60% larger in diameter than a 357, they work just fine at such velocities, while the .36" bullets tend to need another 100-200 fps for reliable, full diameter expansion in flesh. Not, jello, not water, but rather, FLESH and blood, especially with CLOTHING in front of the flesh, to clog up the hp.
