I'm considering either of these, among others. I've heard both good and bad things about the Glocks in 40 S&W. Do some 24s have an accessory rail? I'd prefer the 24 if it did, otherwise I think the 35 would be the way to go. Both are similarly priced. What about parts interchangeability? Are the mags from the 22/24 usable in the 35, including hi-caps?
