So tell me about the Sig Modular System (FCG).

So tell me about the modular system of the fire control group for the Sig.

Are these interchangeable between different models?

The grip is not serialized as others pistols are from what I understand. The modular FCG appears to be. So are these able to be dropped into other frames?

For example, can you drop a FCG from a Macro X into a standard 365 or into an SAS?

Can you change calibers like an AR?

Thanks!

Before the answers confuse things more, there is not one universal Sig handgun FCG.

P365 FCG and P320 FCG are two different systems. P365 is 9mm only. P320 can be different calibers.

The old DAO P250 FCG can go into many of the P320 frames too. Need the P250 slide though.

These are the same FCG for the P365 in different Icarus grip modules. The FCG only works in a 365 module but you can customize them a lot.

Whatever config you want…just buy grip module and slide assembly. You can mix and match.

The P365 FCG works in their 9mm or .380 grip modules

320 has 2 fcgs, .45 and other than .45. And they won't sell you a .45 fcg.
