I've had the Sig TACOPS for 2 months - love the gun, less recoil than the P220 in 10mm, hot loads are very accurate (Blue Dot, Power Pistol, CFE Pistol), and loads around 1100fps with 180gr also work well.  Close to 1000rds so far, 100% reliable.

If you like 1911s, you'll like the Sig.

For the same reason I use a suppressor on a centerfire rifle, I use a Silencerco Octane to lessen the amount of noise while hunting or sometimes for a quick shot or two with the 10mm.  Suppressing a .308 round traveling 2500fps to a level of an unsuppressed hi-velocity .22lr is a good thing.  Ditto for the 10mm.  I don't have any fancy decibel meters to accurately measure the reduction, but the 1200fps 10mm round is significantly quieter using a can vs. without.  As quiet as a 900fps .45acp?  No.  But it is quieter. 

Buy one that can be used for smaller diameter cartridges simply by changing the piston and you've made a good investment.
