I have had a Tac II 45 for about 2.5 years. I put about 1,500 round through it. It has been back to NV twice for several items. But for the most part, it was repaired. The only thing that is still a nagging issue is the case ejection lands forward of the gun. Therefore, I have difficulty at a range retrieving my spent cases.
The gun is dead on accurate, and has just the right features. As far as ammo goes, it does not like flat point bullets or semi-wads very much. I simply love the gun though and do not regret buying it. I bought mine from an LGS that I do not do business with anymore. Most of the people in there are a bunch of jerks. It was my first 1911 and I needed help with field strip and reassembly. The open plug caused me problems. Not anymore.
Long term, I think you will be very pleased with it. Even if you have a little break in issue . I will probably never sell mine. I paid 589.00 for mine. At the time, it was an ok deal. Not fantastic. But, OK.
