hi i am new here, i hope i posted this question in the right place. My question is, what is the twist rate on the 4" barrel on the SW40VE. i was at the gun show here in Oregon last week looking for a good hand gun for under $400, my friend wanted me to get the glock 23, but they wanted $599 for those, so i bought the next best thing. I have looked all over the net for the last two days and i cant find any COMPLETE breakdown guides, or a really detailed specs. can any one help, please.
