How reliable are the 8rd magazines for these two types of handguns? Since both guns were originally based on 7rd magazines. As for the Sig. I'm talking about the factory 8rd ones (or replacing the follower/spring of a 7rd magazine with a 8rd one). I know for the 1911 it is kind of a general question for them since there is a lot of makes of 1911's and magazines. The Sig I already have (with 7rd magazines). In the next 2-3 weeks I'll be getting a Kimber Custom Classic Target (if this helps). I don't mind using the 7rd capacity ones for both guns. Just wanting to know of other options.
