Consider the 'fluted barrel' to help disipate heat from "rapid" fire,I kinda like the swivel hammer since I've found no hammer extension for the Encore!
Knowing me though,If I had the money,I'd probably buy one!
But yeah,I have to agree with the stock comment.Instead of forking out the $$ for a thumbhole from SIR,maybe I'll just wait for a "Sims/Flex Tech" type stock to come out on the market?
I do love my "Encore " though!!!!
