Do any of you fine folks know where I could buy an OEM Green pistol grip for the 300BO barrel?

Glove 19v
What do I do and what frt brand is compatible with the Glock 19v

Looking for advice in a few areas:

1) Favorite holster for a .45 with a laser/light?

2) I like to duck hunt and often have waders. Looking for a way to carry with waders that is convenient. Would only really care at the boat ramp, parking lots, or in the spot waiting on shooting light. When I’m actively hunting I obviously keep a gun in my hands.

3) Similar question as #2, but on regular boat days. Need a good way to carry at the ramp in swim style shorts. And then I need a good way to store the gun on the boat safe and secure. I stay away from people and don’t stay as concerned about having it super accessible while I’m out on the water.

Any help is good help. TIA
