Do more shooters own only 1 contender frame and just convert between the rifle and pistol versions or do most own two frames - each devoted to a particular use? Is there any problems, i.e. accuracy concerns, if you switch between rifle and pistol setups on the same frame? I am rather new to contenders, compared to most on this site, and own several pistol barrels, but I wanted to start into the rifle setups. Any advice would be appreciated. Thanks
