I have 3 Tacs and 2 Mark 23s. Worth the extra money, depends on the shooter. If you plan on taking it into heavy combat then yes, the way the Mark 23 is over built it offers a real since of security. But if just for shooting at the range or light duty use, then the Tac will serve you just as well. Both are more accurate than the shooter and while the Mark 23 has a bit less recoil due to its size and weight, the Tactical is not bad either. If you have the money for the Mark 23 then get one; if you plan on collecting HKs then you MUST get one, but if you don't have near two grand to drop do not feel in the least that you are settling for second best. There is not a darned thing wrong with the Tactical.
