Purchased this as soon as I saw it ... I looked for this particular gun for 7 month because I own 2 S&W .40 Cal semi-auto, like the caliber and do not want to stock too many different calibers. I have put about 120 rounds through the little gun on 2 separate occasions and never had an issue. Hits the target great at 7 yards which is saying a lot for me since I am not a very good shot. It's a good light carry and you can use and carry the magazines from your .40 semi-auto guns as speed loaders. I also bought fast loading strips that take the caliber (38, 357 & 40) which are lighter that carrying a magazine. Good buy when you can find it...
