Plums on dwarf root stock?

I have planted two plum trees (opal and victoria) this year back in April out on the allotment that is on dwarf rootstocks, no fruit on them this year, but they're still alive so that must be a good sign lol.  I did plant a conference pear on dwarf rootstock Nov 2011, and i'm just starting to pick some lovely pears. 

I got mine from GB too, 3 out the 5 trees died in the first year though, hence me planting more trees this year.  Nice to know someone had success with them, gives me hope 

M27 and M9 are apple rootstocks    All the trees we get in at work (garden centre) are either on Pixy rootstock or St. Julian A.  Pixy gives the smaller tree 

I haven't grown one myself, but I have visited our fruit supplier and seem mature trees planted up there.  They were full of fruit but they are quite round headed trees (if that makes sense), so you would need to give them a bit of room

The size of the tree is important, I want to grow them as a cordon or better still a espalier, that's why I was asking about M27, it being just about the most dwarf root stock there is. Pixy is just a little to big for my plans.

There is not the range of rootstocks for plums as there is for apples.
For plums you basically have Brompton, St Julian A and Pixy, Pixy being classed as semi-dwarfing.
There is no equivalent to the apple rootstocks M27 or M9 that is available for plums.

OK, thanks for the info, that's what I wanted to know, IE was M27 a possibility for plums. so I will have to try "pixy". the problem is; the trees have to go next to a wall with 1 meter deep foundations and the wall is only 2 meters above the ground level. Thanks all.
