I have an older Contender and presently am awaiting a G2 contender carbine in 22 rimfire delivery. What can I expect in the way of trigger adjustment with the G2. Will I be better off putting the G2 barrel on my older frame which has a very good trigger. Is the G2 stronger? Is the grip angle truly an improvement? My early Contender has had many barrels on it and I consider it the best hunting handgun I have ever used. I plan on putting a 10 inch 44 magnum barrel on the frame that shows the least promise as to trigger pull but it is an older barrel and will it work on the G2 frame?
