Thanks. I would like a mag well, and I think if I do anything I'll put in a 6.01 barrel with a decent hop rubber. As accuracy is king, I'm more than happy with the rof so don't want to mess around with slides and springs. I'm thinking if it ain't broke don't fix it kind of thing. I must remember this is a back up and room weapon. Money would be better spent upgrading the cm-016 at this time I think.
