Nice 99 edp, yes they extremely comfortable and solid - right now the P99 is my carry piece, in a CompTac IWB holster. I'm awaiting a IWB from Brommeland Gunleather for the Kimber II, which I'll use primarily in the winter months.
The Nova was kind of an impulse buy - wife said its been so long since "we" had a shotgun, and after holding the stock Moss 500, Rem870 models, she liked the fit and feel of the Nova best. The only thing left I think is that i'm considering the 14" LOP Comfortec (sp?) buttpad. It'll make it about a half inch shorter for her and fine for me either way. As for the recoil reducer, not yet, from what I understand the most noticeable difference was when firing 3-3 1/2" mags. Seeing that she'll be fed a constant diet of 2 3/4's for now, I may decide to eventually pick one up to better handle the heavier loads.
Received the Nova 2 shot extension today, real nice - but the only one I could find under $100 was the RealTree finish. I'm going to Duracoat it in matte black, and have the finished product to show probably in a week or so.
