Yaasmiene, unfortunately no it won't fit. The TR laser won't fit a gen 3 because it has a picatinny rail. So you need a laser that will fit a compact/subcompact picatinny rail. Here's a link to one that should fit and function just fine if interested. Hope this helps, link here.................. budsgunshop.com/product_info.php/products_id/118887/iprotect+6117+q-series+sc-g+green+laser+5mw+any+railed+handgun+532+nm+wavelength+black

Yaasmiene, not sure what James is looking at, but if you follow his link, it states right on the product page "TR10G GREEN Laser for SCCY CPX-1, CPX-2, CPX-3 & CPX-4, DVG *******(does NOT fit Gen3 with Rail)*******" .....The trigger guard has nothing to do with it, it is the rail. There is no CPX-2 Gen 3 without the rail. I actually own the CPX-2 Gen 3, and the Armalaser TR laser will not fit on my gun.

Hi Yaasmiene, The TR Laser I was referring to is the Armalaser TR Laser. All of our SCCY firearms feature the same trigger guard. Armalaser will fit CPX-1, CPX-2, CPX-3, CPX-4, and DVG-1 (including RD models). https://armalaser.com/tr-series.html

Yaasmiene, no, the TR Series Laser sights will not work with the SCCY CPX-2 Gen 3 model, as the Gen 3 has a pic rail that will interfere with the installation. It will work with Gen 2, but not Gen 3. There are none made specifically for the Gen 3, but you can get a generic laser that will mount on your pic rail, but having less than an inch space, your choices are slim. Here is one that should fit >>> amazon.com/Pinty-Compact-Tactical-Picatinny-Wrenches/dp/B01BPYEAKA/ref=sr_1_15?keywords=rail+mount+laser&qid=1685099660&sr=8-15

Hi Yaasmiene, yes it will fit no issue. Red is fine but Green is best. It a little more $ but worth it. Cheers and stay safe!
