Exactly. Firearms can be quite heavy. It doesn't make sense to spend thousands to save a couple hundred grams on wheels or a groupset and then carry a sidearm that's needlessly heavy.

Also I wouldn't phrase it, "wants to kill someone". That's the wrong message to send to people. Probably those bike-jackers parents had this kind of thinking! Responsible firearm use is only for when it's needed to protect yourself or your property. Thank you for your understanding.
