I'm looking to mod a gun (threaded barrel, silencer, optics, trigger upgrade, stipple, etc). I have a Glock 17 Gen 4 but I'm thinking about selling it for a MP2.0 and mod that or just buy a FNX 45 tactical which is pretty much upgraded stock. Any ideas, advice, suggestions? I already have a G19 so I'm thinking of adding a variety by getting the MP or FNX but some of my friends are saying to keep the 17 and start from there. Thanks!
