Hi and welcome. I would contact Langdon Tactical with the UPC/Model # for an answer at PHONE: (571) 385-2979 · EMAIL: contact@langdontactical.com ------ Cheers, stay safe and enjoy!

we have no way of knowing if it will have the gray trigger you would need to Contact Buds customer service (859) 368-0371 available 9AM to 9PM EST Monday through Friday or use the blue chat now button and they will help you . We are not buds employees we are volunteers that answer questions

It may or may not come with the gray guns trigger. You can't go by the photo, it is a stock photo. Unless you order direct from Langdon Tactical ( https://langdontactical.com/beretta-px4-full-size-g-sd-by-ltt/ ), you do not know which options were installed. Perhaps Bud's customer service can answer this at 1-859-368-0371 9am-8pm EST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 8pm Mon
Stay safe & have a great day!
