I have owned a Nelson conversion for several years, switching it on and off my Springfield Range Officer. I decided I wanted a dedicated 1911 frame for this "upper". I chose an inexpensive Tisas and found I needed to make a simple and inexpensive modification (changing the mainspring) to make the conversion work reliably with CCI Standard Velocity ammo. You can read about this modification here >>> https://drive.google.com/file/d/0B8b...ew?usp=sharing.
