I'm considering one of these for shits and grins. Most of you dont already know that i'm a Sig whore, with 3 Sig Sauer Classics to date (2 P229 .40 and 1 P239 .40). I ran upon a great deal on the Sig Pros... $399 brand new. I'm not a huge fan of polymer frames due to their unusual weight characteristics once the mag starts to go empty, and in the case of my Glock and other ploymer guns i've checked out, they tend to have a slightly looser fit at battery between slide/frame... this i assume due to rail design to prevent metal to plastic chafing. but $399 is $399. i have held them in my hands before, and despite the balance issues, it feels like a Sig. i like the integrated rail, which encourages me to want this for a home gun, outfittable with accessories (i stopped modding my car so i'm suffering mod withdrawls ) the sucky part is it's not a picatinny rail, so i have to buy Sig only accessories. anyone else ever had one or experienced one to give me some first hand knowledge?
