I've been looking around a lot and reading a lot of forums and discussions on guns and as you can imagine I've seen glock sig and beretta being brought up a lot. I've been leaning towards the sig p226. However I have a few questions about it. I've shot a gun before many times so I have experience. If you could please answer these questions for me it'd be much help! 1) is a sig a good gun to buy if I wanna have it for 50+ years if kept in good condition. 2) is it worth it to but it brand new or better to save money and get it used? 3) If better purchase new, how do I go about getting one from the sig factory new? 4) any other guns you might suggest instead?
