Please help me in solving a mystery for me. I have searched the internet high and low to find out what the real differences are between these two guns. I want to purchase one of them but cannot decide which one. During my internet searches the only thing that I can find different between these two guns are as follows:
1. MK23 is a much larger gun.
2. Manual hammer release lever on the MK23.
3. Some kind of hexagon barrel.(I am not sure if this is in the USP but I do know that it is in the MK23)
That’s it. That is all I got. Now there has to be more to the MK23 than what I have mentioned above. I say this because the MK23 is physically larger than the USP and cost double. So what am I missing? Is it double the cost simple because the gun is labeled MK23? Does the MK23 actually perform any better then the USP Tactical?
