Found a 3" fixed sight gp-100 hiding in a plastic tub of loading dies. I think I had originally bought it with the hopes of having dave clement convert it to 10mm or .41 special.

Too big for conventional inside the waist band carry for me but it just disappears into a fat man's overall back pocket.

What would you all recommend for defensive ammo ?

Double tap usually has a promo code like 30% off retail and you can order it direct. I carry My 3" GP and 5" Ns IWB all the time.

This is a customer's 3" GP 100 in .44 Spl. I carry mine in the same holster. Nice gun for around the farm.
