New here!!!! A great forum with people that appear to be very knowledgeable and willing to help. I am trying to make an educated and informed decision before I spend my very limited retirement income on a nice handgun. I have spend time on the Sig Forum and find a situation that keeps coming up on Sig manufactured handguns:the slide is either quite loose when you buy it or it will shortly become loose. I handled a new Sig 239 in a gun shop and the slide rattled on the frame, brand new. It appears that a loose slide does not affect accuracy but adds to reliability, as the lockup that is important is slide to barrel. l have narrowed my choice down to two guns, H&K USP full size 9MM and a Sig 226 9MM, and after handling and shooting both I can't decide because both were superbly accurate and completely reliable and fun to shoot. I would be happy with whichever one would be the most durable and remain the tightest over the years. I will be using the gun for target and plinking etc. So, after this lengthly first post.....will the H&K USP full size or the Sig be the most durable and remain the tighest? Again, I know the looseness of the slide probably doesn't matter but I don't want a gun that rattles!!!
