Following the video tutorial on tthe sub frame removal, he shows a safety (?) pin and spring that has to come out. My MA-1 does not have this. The lock pin seems to be hanging onto something and I am afraid to force or pry. Is there some other release spring on this newer model? Excuse the lack of official terms, but I do have mechanical abilities to take it apart to clean, not repair. Thanks for any help

Since yours doesn't have the manual safety, then all you have to do is remove the disassembly lever then use the supplied 2 pronged key to push in the key lock far enough to start lifting up the sub frame. Some of the disassembly levers are harder to come out than others and I believe that's mentioned in the tutorial. Is that what's giving you a problem?

See this thread for a parts diagram. http://www.steyrclub.com/vb/threads/2802-Steyr-M-M-A1-S-S-A1-Firing-Pin-Safety

yes the disassembly levers can be a real booger to get out. i have found that rotateing them around a little while pulling gets them the rest of the way out after the initial pop out while lining up the lever with the line. there are vids about it on youtube i think. the steyrs are not quite as simple to disassemble and reassemble as the glocks are, but not overly complicated either.

Thanks Dash and Khoff. Yes, that is my problem--pulling that pin out. I don't know how much force to use before I booger it up.

When you get it apart, you'll see that the lock pin has a groove in it, into which the slide lock fits. What you are trying to do is center the pin in slide lock opening (it's just a circle slightly larger than the pin). Sometimes pushing slightly forward on the slide lock will let you manipulate just enough...

Once you've done it, you'll see a pattern to the feel, then it comes apart easily. Personally, I'd have made it so that when the lock pin is down, there is no groove in the pin.

My CZ 75 B just has you move the slide rearward to align the mark on the slide with the mark on the grip and lightly tap the pin out. The butt of a mag works perfectly. Much easier.

A lot of guys say that lifting up on the slide lock lever helps to get the disassembly lever out. I have personally resorted to a brass punch and a firm tap on a couple of occasions - it definitely doesn't like to be removed.
