I'm wondering if a 38 super firing pin is any less durable and/or reliable than a standard 45 firing pin. I ask because I'm thinking of getting a new 1911 and am wondering if that should be part of the criteria I use to decide which one to get. Also, I'm a pretty big fan of slim grips; are they usable with a 1 piece magwell/mainspring housing set up. If they are, will I have a big gap between the grips and the magwell? I'm thinking pretty hard about a fusion 1911 kit, specifically either the combat or riptide.
