It was $385 + shipping, I have $255 in parts.
Total believer in the Tisas
A 2017 Springfield armory range officer elite champion 9mm for the last 6 years.
When the factory Black T finish wore, I had it stripped and deep hot blued.

Ive:
Replaced the ambi safety and plunger assembly, now I have a positive safety.
Replaced and fit the Nighthawk magwell and beavertail.
Had to file. 007 off the frame to make the nighthawk fit.
Polished the sear and disco to get a 3.7# trigger...
