I'm considering buying a G1 Takara Megatron but have question regarding the two different types I keep seeing. The first version looks like the original chromed P-38 while another version has an orange cap on the end of the barrel that is obviously for safety reasons. While the one without the cap appears to be slightly cheaper, my question is whether the cap is removable on this version. If not, I'm inclined to get the more expensive version without it. Thanks.
