"Pretty much a drop in fitting with an Airsoft Masterpiece slide. All I had to do was lube the slide and frame up and slowly rack em back and forth until they loosened up like butter.

"A fair bit of warning if you choose to buy nineball hi capa products. Nine ball created their modern line of hi capa upgrade parts with the intention of the consumer switching out the parts from a stock tm hi capa, so if you're doing a ground up build, I would avoid nine ball. I learned this the hard way

This lower frame, for example, does not come with the side panel, so if you don't have a stock tm, or another hi capa to take the side panel from, then this frame is absolutely useless.

The nineball extended mag release does not come with the internal spring, so again, if you don't have another mag release that you can take the internal spring from, then the nine ball mag release is going to be absolutely useless for you.

The nineball hammer does not come with that hammer bar that connects to the grip mainspring housing, so again, you need another tm or hi capa to take the existing part from.

The list goes on and on.

I'm not trying to bash on nineball, just trying to spread the word out there that nineball hi capa parts don't come as a complete set, and REQUIRES you to have another stock tm on hand to swap out the missing parts for.
