I know there are some Delta Elite experts out there.... Here is my question. I just picked up a used DE today. It has an comp that is connected to the barrel. When you remove the barrel it stays attached. Not screwed on... it looks like the bushing type. but... is held to the gun with a two piece guide rod and recoil spring. The guide rod screws together. I did figgure out how to take the pistol down. Question is.. is this a common comp or what. Can it be converted back to a bushing system without the comp? It looks like there are no locking lugs inside the slide for the bushing to lock into. Thanks in advance.
