With my new can (Sparrow .22) I was looking for a threaded 22 pistol. When I spotted the Sig 938-22, I knew I had to try one out. Heck, as long as I was getting the 938-22, why not pick up the Sig 938 in 9mm at the same time. I've put around 300 rounds through each so far with zero problems and I'm really liking the pair. The sights are fully visible above the can and the accuracy is excellent.
