Just picked up my HK45 and my USC 
The first thing I did when I walked in was to try the HK45 in the Safariland 6281 holster made for the P30.
It does NOT fit.
It is not even close, so I did not bother to take and post any pictures. The HK45 does not even slide far enough into the holster, it is sticking out at least an inch AND the decocking lever is in the way. Forget about the retention strap
