Cool, I guess. But no grip safety, different recoil spring assembly, SIG magazine (good idea) why not just by a 320 with thumb safeties? No idea what a good 320 hammer/trigger pull is like but my 2.0 M&Ps with the Apex trigger kits are just amazing. Does anyone do similar kits for the 320's? for the difference in price you could get some work done on the 320 if something didn't suit you.
