Has anyone weighed their "SP01 Compact" yet? It does feel a little heavier empty than my aluminum-framed P01 does loaded. If I had an accurate scale I would weigh it myself. Personally, I really like all-steel pistols (which is one reason my Shadow is my favorite pistol and the SP01 is a close second), so this is not a problem for me. I'm sure it would make a difference on one's back if carried at 3:00 or 5:00 all day, but the SP01 Compact doesn't bother me at all carrying IWB appendix carry. I've been carrying it ever since receiving it - along with my regular carry pistol since this new one hasn't been proven out yet.
