Well i think i have a change of plans. Originally i was thinking of building a rifle in a saum. But the action came in and looks like its an undesignated action. So im really considering building a rear grip sp! How would i go about doing this? Ive been drooling over some of the pistols here for a while and had no luck finding a cheaper xp to build off of so this may be my best bet! I want to build it for long range hunting and target shooting and really thinking of one of the short mags. Guys got some ideas where to start? Thanks guys!
