Today was my third range trip with my SW 640 Pro and I gotta tell ya, I really like this fantastic gun. The first trip I had Moon clip issues, but got those resolved and now carry this little beast daily in a Galco Tuck and Go as mentioned by a member on this forum. I settled on Speer 38+p short barrel for SD and against my previous better judgement, installed a set of CTC LG405 lasers on it today. After initial zero, this gun, as a friend of mine says, is bulletproof. Great gun.
