Mark IV Problem (Self Induced)

Only I could do this. I bought a New Mark IV target today and tried out the push button disassembly. Of course it worked great. Somehow, though, I let the hammer go forward and now I can't get it to cock so it will go back together. Hopefully one of you guys has a suggestion.

Use your thumb to pull back the hammer until it clicks. No harm. No foul. I do that on my Mark IV all the time.

+1 If the barrel is off the frame, you should be able to manually cock the hammer back until you feel it click in the cocked (parellel to the slide) position. You can manually firethe pistol like that with the barrel off if you want to see how everything moves, just put the palm of your hand against the hammer so it doesn't fly up with any resistance.

If that's not your current situation, please elaborate.

Unfortunately, that is not the problem. The hammer is more or less vertical with only a little play forward and backwards. It will not cock - when I try, it feels like the hammer strut is hitting something solid instead of the main spring. It looks like it is sitting on the mainspring though. It has me baffled.

If the magazine is out and the hammer is fully forward it will not allow you to cock the hammer. Insert the magazine and then cock the hammer.

Also if you push the hammer down too far and the trigger doesn't allow you to release the hammer. Push up on the safety and it will move the hammer to a position where it will fire.

Well... I'm not sure what I did, but I think I did what you guys told me to do. Anyway, it went back together, functions, and I've had it apart two more times with no issues.

Thanks for all your help! I truly appreciate it.

Guns are puzzles. The more you work with them, the more intuitive they become. I remember the first time I disassembled my 1911. I started with the slide lock pin and then tried to put it back. OHMYGERD! I couldn't get it back in and then... I scratched it. Arrrrgh! So, then I pulled out the pin and figured out how to put it back in. After I got that down, I pulled the barrel collar off and kept getting progressively deeper. Now I can pull the entire pistol apart and (more importantly) put her back together again.

In cave diving we call that progressive penetration. The fool swims 2000 feet in a cave on the first go. He probably only does that once. The smart cave diver peaks in and then goes home. He does this a bit deeper and deeper until he learns the cave. When he finally gets 2,000 feet (or more) back, he can probably make it back without a line or a light. We feel the eddies as the water flows around obstructions. It's way fun... but you don't do it all at one go. Little steps. Keep it progressive. If you feel the willies, go ahead and bail on the dive. The cave ain't going anywhere.

That's good advice and a good analogy NetDoc. I've had a Mark II Target since they were introduced. It took me a few tries, but now I can take it down and reassemble it in short order. I also have a Mark III .22/45 Target. That one is the worst ever to reassemble. It's down to a bore snake, brush and Q-Tips when I clean it. Otherwise, I have to use a plastic hammer and a brass punch. I put a Volquartsen kit in it a couple of years ago and it has a terrific trigger and is deadly accurate. It's also picky on ammo and the magazines don't always latch. I'm hoping the Mark IV will not only be easy to clean, but be accurate and reliable.

I have to say, that the one button take down appealed to me. Oh, I love the looks of my hunter as well. Just put a holographic sight on it today and tomorrow is range day for me. Can't wait!!!
