Because of the way the 1377 is designed it is not possible to easily attack a laser sight to the pistol underneath. There are a few custom shops that manufacture a custom breech that is longer than the stock breech. Crosman even offers one. You might be able to attach one there. I've attached a scope to one of the 1377's using Crosman part (459MTC) it a Crosman Airgun intermount for scopes. Click on the link below to see the Crosman accessories.
