It has a "firing pin/striker block" and it looks like it has a rebounding hammer. Basically, it comes down to weather you want an Italian (Uberti) copy of an 1873, or a Japanese ("winchester") copy. I have three "miroku-chesters" (1886 short rifle, and two 1895s) and they are fantastic. I love them. But they are just Japanese copies of the original Winchesters. For my money, I will stick with my more historically accurate Uberti 1873. If you just want one that has "WINCHESTER" stamped on the barrel, buy one. It will likely be a well made rifle and you will probably love it, but I wouldn't say it's a "real" Winchester. The barrel will also be stamped "Made in Japan by Miroku".
