Took my new NRA Mark II out for a second range session today. I put 350 rounds through the pistol with 2 malfunction early on. Both were failures to extract of a type that I’ve not experienced before with any other pistol. The spent casing gets caught in the closed bolt with another live round partially in the chamber. I have to drop the magazine and retract the bolt & both the spent casing and the live round drop out through the mag well. I also had this type of malfunction once during my first range session. I’m really not concerned as malfunctions have been infrequent & the pistol seems to be otherwise reliable. I only have about 700 rounds through the gun, but I am curious as to whether this sounds like a extractor issue or a cheap bulk ammo issue. Do other Mark II users experience this type of malfunction? In general I’m very happy with the pistol & would recommend it to anyone considering a Ruger 22.
