buy the G2 contender frame you will like it better.
Go to gunsamerica, gunbroker and auctionarms sites.
do internet search for contender barrels and 4-5 plus sites will come up
I have had the 10", 14" and 21". Go with the 14"
is a good site for T/C info
If you want to use for LR varminting, then the Burris 2-7, 3-9, 4-12x LR pistol scopes are the best pistol scopes.
You can find a good used Nikon, Leupold or T/C fixed powers on ebay reasonable. T/C also has a 2-7 that is decent. The others all have extremely limited field of view IMO except the ones I named.
