I would get the basic shield 2.0. Inwould then go buy after market sites such as ameriglo or Trijjicon or orher fiber and tritium night sites of your choice. My favorite so far is ameriglo Idot pro.

I habe gen 1 shield with factory tritium and juat got a 2.0 9c in 3.6” barrel. I thiught I would hate the rough 2.0 texture. But so far I love it. If anything, now the 1.0 shield Grip is way to slippery.

If you dont like the original std trigger you can always upgrade. The std 2.0 trigger I think is pretty much the same as the PC trigger. But I could be wrong.

The 3.6” 9c is “only” half inch longer barrel but grip length is the same as the shield with 8 (plus 2 magguts). But being a double stack get 15+1 capacity. If you can stand the extra width and weight. I would go with the 3.6” 9c over the shield. I’m starting to wonder what situations I cannot carry the 9c but I could carry the shield. I’m thinking Not too many.

The 9c also comes with x grip extensions so you can use the std full size 17 round mags as well.
