TM1 Question

Hello All! I have been shooting a Perazzi TM1 for quite a while now. It had been serviced at Giacomo just prior to me shooting it. To this day, gun locks up tight, and is in great shape. Here is my question. The last thousand or so targets, I am thinking I see the top lever swing right, and back to closed position in an instant when fired. I really think I see this occur using 3 dram Handi loads. Is this a possibility, or am I just seeing things? As stated, gun is rock solid tight, and I do not see any worn parts, or broken parts. Thanks for the help...

 

One of my TM1's did he same thing. Had it serviced years ago and worked fine after ever since. Don't remember who did it.

 

I think it was a locking lug thing.

 

Thanks for the reply...now I don't feel as crazy!!

 

Go ahead and have the locking bar replaced, the next stage will be the gun popping open when fired................

 

Sounds like it might be time for a new locking block and spring. I'm guessing your lever is probably centered or nearly so with the barrel closed?

 

The design is fairly simple. The lever is for releasing the locking block...that's it. IF you are seeing the lever move, it's because the locking block is not properly seating. There is no "play" in the locking block/lever mechanism that would allow the movement you describe. First, dis-assemble the receiver and thoroughly clean it. Then properly grease it and re-assemble. Replace the return springs (inner and outer) while you are at it. Most issues will be resolved doing this. If that doesn't fix it, I concur that a replacement locking block is in order. Not a big deal, but it must be done right or you will have no end of problems. Also, pay attention to the advice provided by mpolans. Do not allow the locking block to wear to the point that it is at or near the "6 o'clock" position with the barrel closed.

May have to much oil on it keep it dry

 

Lever is getting close to pointing true 6 o'clock. I will look into getting it checked at the Grand. Or, if Karl McKnight is at the PITA grand, I could run it over to him...Once again, thanks for the advise!

 

good choice C-Money Karl is one of the best around .

 

Yep. Take the barrel off and see where the lever sits. Then put the barrel on and compare. The lever should be further to the right with the barrel on. If the lever is just as close to center with the barrel on as the barrel off (or nearly so), I wouldn't shoot it as it's very likely you'll need a new locking block and top lever spring. Continuing to shoot it with a worn locking block and spring can result in the top lever shaft snapping in half.

 

A new top lever spring would help a lot...

 

C-money, Have Karl do the annual on your gun. It will come back like new. Roger C.

 

I ended up having Pat Tully look at my TM1. He recently put a Rad Pad on my daughters gun. While visiting with him, I asked him about the problem I was experiencing. He said he would be glad to assess my gun issue. It is fixed, he advised it was two springs needing replaced on the top lever. Glad it was simple! Pat is a great fellow to work with, and I would highly recommend him.

 

So, all it needed was 2 little springs.

Imagine that

 

Yep! Just two springs. I didn't realize how light the tension was getting on the top lever. Lever is tight now!

 

A highly regarded former shotgun gunsmith once told me to put a piece of clay doo (sp?) up against the top lever with the gun cocked. After firing the gun there will be marks in that material showing any movement of the top lever. FWIW this was with a TMX model.

 

Cargodog, that is a pretty good idea! Daughter and I hit a 50/50/25 shoot Saturday. This was the first time shooting my gun since the repair. It was flawless. Defiantly noticed the stiffer springs. Zero top lever movement. I tried out my new shell carrier/pouch that I won in the spring. I really liked it, and was honored to wear it. My little girl shot very well. Her scores are really getting consistent, peeks and valleys are flattening out. We had a great day.

 

Sounds like a great day for both of you, memories made.
