I want to get an Advantage Arms .22 conversion. I am contemplating which one to get. 1. Get the 17/22 - I have both so I could switch back and forth between two models - also have the 34 and could put it on that frame also. 2. Get the 19/23/32 - I have the 32 with a .40 and 9mm barrel - This would be my multi-purpose/Bug out gun - One frame 4 different calibers. I only have enough fun money for one - so don't say get them both! Thanks.
