M&P / Open Minor questions

[Lior]

Hi folks. To date I've cut my teeth on the Gen1+2 M&Ps, and today shoot mostly the M2.0 CORE with an unported barrel (IPSC Production Optics Light Division).

I'm interested in getting a ported M&P for occasional Open Minor use (we're limited to factory ammo and 9X19 115gr. is most common).

My questions:

1. Is there much of a performance difference between the Gen1 and Gen2 ported M&P COREs? (5" bbl)
2. Is there much of a performance difference between the ported Gen1 9L and the unported M2.0 (the latter which I have)?

By performance I mean general shot recovery to sight picture and being able to imitate Jerry.
I'm asking because there's an imported Gen1 9L of 2018 vintage that I can get my hands on, and if I take the M2.0 route, I'll need to import it privately (major hassle). I've shot other Open guns in my time (Bul SAS2, CZ CzechMate) but the M&P just fits my hands much better.

Thanks for any inputs guys.
