Im pretty much a gun enthuisiest. Been itching for a carbine like my old mini14 M1 I owned a H.P. 380 pistol eons ago and hated the look and due to a national shortage of ammo, never got to shoot it. I read reviews on the 45 carbine from H.P. and saw several youtubes on it. Then saw the Hickcock vid " sorry if mispelled. After that i ordered it today. My first order of business is to fabricate a large cap magazine for it possibly revamp the mag slot to accomidate a wider mag design. Not sure it exists yet... but im going to make a 40 hipoint cartridge.. 45 necked down to a 40. This will improve cambering issues. And going to manu. A better ejection system other than a firing pin ejection. Since the most important thing is to go bang.. Im just going to add an ejector tab, add a recess to permit new ejector tab to do its job before the pin does.
