So I am really thinking about a 10mm for some reason and really only Glock, SA, and Sig have models I would consider and the Sig is the least favorite there and I shoot like crap with Glock so I am guessing that leaves the SA and I am a fan boy of sorts anyway so, there's that. Anyhow they make a 10mm OSP version but it has suppressor sights and a threaded barrel. I really don't like the look of either. If I just buy the regular version how hard is it for me to get the top milled or what needs to be done to put a Vortex Venom one top?
