Things I liked: This is a great replica of a S&W Sigma pistol. This has a great trigger pull. There are many metal parts, and it field strips like the real thing. The outer barrel and recoil spring/ guide look like a Glock. This would make a great trainer for a Glock owner. It is a good shooting Airsoft Pistol.
Things I would have changed: I wish that it didn't have the Firepower graphic which takes away from the realism of the replica. I wish spare mags were available.
What others should know: I usually only put 10 rounds in the magazine and shoot two 5-shot strings of fire to make the CO2 last longer by preventing cool down.
