I just picked up this slide on gunbroker: http://www.gunbroker.com/Auction/ViewItem.aspx?Item=359244254

Will it work on my T9 frame with a new barrel,magazine, guide rod, and recoil spring to convert to 40 S&W? Also, would it be possible to do an extractor swap and use it to shoot 9mm or am I going to run into breech face issues? Perhaps someone who has a T9 and a T40 would be kind enough to see if the slides would interchange. Any info would be appreciated. Thanks in advance.

If it ends up not working, it's still a good deal for spare parts.


Here is the update. Sorry it took so long. Had quite a few issues getting this to work. Short story: Bead blasting would not take. The consensus was that it was plated or hard chromed. The barrel lug had to be ground down in order to not strike and lock up in the T9 frame, and the sights were a HUGE PITA to install. I had to file off several thousandths on the front sight and then use a pusher and then finally a hammer an punch. Luckily I did not shatter the vial.

She may not be pretty, but she is functional. Here are the pics.

I have swapped my mk40 with my mk9 they will slide on but will not operate correctly. The mk40 mag will not go into the mk9.

I was always curious of the same thing so I did test them. I have both Pistols (T9 and T40). The frames and slides (complete assembly) will interchange and function properly. I have not actually fired them this way, but only cycled rounds through ... but the the test function was so perfect I would not be afraid to try it live fire. They will not work as "barrel swap only".

If I had seen this post yesterday I could have tried it for you, as I went to the range yesterday .... sorry about that.

That slide has had some customization done to it. Never seen those fluted grooves in the top ... nor that particular rear sight ??

Thank you very much! I have one more question if you don't mind. Could you please see if a T40 magazine will fit in the T9 frame? This could be the last real hang up.


No worries on the test firing, but thank you again for getting me an answer on the interchangeability.

The flutes are what really caught my eye. I think the rear sight is an adjustable MMC. I am not for sure as I have never seen one in person and the photo quality is less than stellar. Perhaps someone with more experience could chime in.

Well ... it would have to or I wouldn't have been able to cycle through, wouldn't it? LOL

I just tested it again to be sure ... and the answer is, YES

Let us know!
