I have a Warthog ,the promlem was a last round nose-diving in both mags.I Changed the mag springs with Wolf springs and gun shoots everything FMJ,hollow points no jams,stalls,missfires.
This is a small powerfull 10+1 .45 gun ,so lock your wrist or hold with both hands it will jump .
After a while I can shoot fast one handed and get good hits from 35-45 feet .I am very happy with this gun but check other gun sites for more info.
The price was $200 lower then other small 1911s.
